Want to take the family on a cross-country adventure? Or perhaps you're planning a shorter trip to your favorite campground. Whatever your destination, it's important to have the right equipment, especially when towing a fifth wheel trailer. To ensure proper hookup and safety while towing, you'll need something to attach your fifth wheel hitch in the bed on your truck. Many pickups come equipped with factory-installed rails or puck systems, but if you don't have one of these already installed, don't worry. REESE has an extensive line of mounting rails and bracket kits, custom-made to the exact specifications needed based on your truck's year, make, and model. REESE also offers several Industry Standard designs, as well as fastener kits, spacer kits, and a Power Puck mounting kit, so you can be sure you're covered, no matter what pickup you're using to tow. So make it easy. Make it fun. Make it REESE, so you can make the journey as enjoyable as the destination.

Reese has designed towing equipment since 1952 and remains a benchmark for heavy-duty towing. The line covers fifth wheel hitches such as the modular M5, gooseneck couplers including the Goose Box, air-ride and short-bed pin boxes, weight distribution systems with active sway control, and the accessories that connect them, all built to exceed published industry standards.
Reese has been pioneering towing performance since 1952, when Margaret Reese asked her husband TJ to stop travel trailers rocking every time somebody walked through them. His answer, the first pair of stabilising jacks, was simple and effective enough to change the RV industry. From that starting point Reese grew into a designer and manufacturer of complete towing systems, and today it anchors the heavy-duty end of the Horizon Global towing portfolio.
Fifth wheel towing is where the brand's engineering is most visible. The M5 fifth wheel hitch uses a modular design that breaks into manageable sections for assembly, with a wider stance, tighter tolerances and a shock absorption system aimed at the jolts that travel up through a truck bed. For owners who would rather tow from a gooseneck coupler and keep the bed clear, the Goose Box 20K replaces the trailer's king pin with a gooseneck connection carrying its own air-ride cushioning.
Pin boxes are a Reese speciality. The 5th Airborne uses air-ride technology to dampen road shock and reduce the chucking motion that makes fifth wheel towing tiring, while the Sidewinder was designed for short-bed pickups, pivoting the connection point so the trailer can turn sharply without the front cap meeting the cab.
For conventional towing, Reese weight distribution systems restore load to the tow vehicle's front axle and control sway. The Pro Round Bar distributes weight evenly while damping sway, and the Pro Dual Cam II uses active cam-based sway control that works harder the stronger the sway force becomes. Complete kits pair bars, head and shank to a rated tongue weight, and dedicated sway control kits can be added to existing setups. The products suit RV owners, horse and livestock haulers and anyone towing near the upper end of a vehicle's rating.

Yes, the Reese Fifth Wheel Hitch Mounting System Custom Bracket RE50140 (Part #RE50140) is designed to fit the 2006-2008 Dodge Ram 1500.
The Reese Fifth Wheel Hitch Mounting System Custom Bracket RE50140 (Part #RE50140) fits the following vehicles: 2006-2008 Dodge Ram 1500; 2003-2010 Dodge Ram 2500; 2003-2010 Dodge Ram 3500. Always verify your specific year, make, and model before ordering.
The Reese Fifth Wheel Hitch Mounting System Custom Bracket RE50140 (Part #RE50140) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
Yes, the 50140 kit fits 2010–2012 Dodge Ram 2500 with a gas engine. However, the installation procedure differs from diesel models. For gas engines, you must install brackets (2) and (4) in reverse positions (see Figure 2A), placing the rear left bracket on the outside of the right rear frame rail and the rear right bracket on the outside of the left rear frame rail. Bed drilling locations are shown in Figure 3A for gas models.
The 50140 kit is compatible only with Dodge Ram Megacab 1500 from 2006–2008. It does not fit 1500 models from other years or non-Megacab 1500 trucks.
The manual provides instructions for both rail kits but does not specify which is correct for your application. Contact the manufacturer or your supplier to confirm which kit (58058 or 30124) is appropriate for your vehicle and intended use. The two kits use different fastener sizes and drilling locations.
Yes, the kit is designed for both 6-foot and 8-foot beds. However, the rear rail positioning differs. For an 8-foot bed, measure 28-1/4 in. (58058 kit) or 28-3/8 in. (30124 kit) from the back of the bed to the back of the rear rail. For a 6-foot bed, measure 26-1/4 in. (58058 kit) or 26-3/8 in. (30124 kit). See Figures 3, 3A, 6, and 6A for the correct drilling locations for your bed length and engine type.
The kit includes fasteners from Fastener Kit 116629. For the 58058 rail kit, fasteners include: 4 u-bolts (1/2-13 x 7-3/4 x 4-1/2 in.), 19 hex nuts (1/2-13 in.), 20 conical washers (1/2 in.), 1 carriage bolt (1/2-13 x 1-3/4 in.), 10 lock washers (1/2 in.), 6 carriage bolts (1/2-13 x 2 in.), 8 u-shaped spacers (2 x 1 x 5/16 in.), 4 carriage bolts (1/2-13 x 4-1/2 in.), 2 tube spacers (2.75 in. long), 2 tube spacers (2.06 in. long), and 6 blocks (1-1/2 x 1/4 in.). For the 30124 rail kit, fasteners differ; see the parts list on page 6 for complete details.
You will need: wrenches in 3/4, 7/8, and 15/16 in. sizes; drill bits in 1/8, 9/16, and 11/16 in. sizes; a center punch; a measuring tape; and a 1-1/8 in. hole saw. All fasteners are supplied in Fastener Kit 116629.
The spare tire should be lowered and removed if needed for extra access to the frame. This is not always required but is recommended to make the installation easier, especially for accessing the bottom u-bolt end on the passenger side rear frame bracket.
The exhaust may need to be temporarily lowered to gain access to the bottom u-bolt end on the passenger side rear frame bracket, depending on your vehicle. There may be retainers on the end of exhaust support rods that must be removed before the rubber isolator is removed. The exhaust should be reinstalled after the mounting kit installation is complete.
The manual does not specify that the battery must be disconnected. However, you must detach the wiring harness from the inside of the driver side frame between the fuel tank and the shock absorber mount before beginning installation, and reattach it after the frame brackets are installed.
No. Do not install mounting rails over plastic bed liners. Plastic bed liners must be cut out of the way to provide metal-to-metal contact between the rail and the truck bed. Mounting rails may be installed on spray-in liners.
Yes, drilling is required. You must drill multiple holes in the truck bed and frame. For the 58058 kit, you drill initial 1/8 in. holes, then enlarge three rear holes to 9/16 in., and enlarge two front bed holes to 1-1/8 in. (top layer only) with a hole saw, then drill two additional 9/16 in. holes in the bed support. For the 30124 kit, you drill 1/8 in. holes, enlarge them to 11/16 in., and drill 1-1/8 in. holes in the bed with a hole saw. When drilling, be aware of potential risks to vehicle components and take appropriate safeguards to protect them from damage.
The 1/8 in. pilot holes are drilled first to mark and verify the correct bolt placement. After drilling, you temporarily position the frame brackets to check that the 1/8 in. holes align with the slots of the frame bracket. If they align, you remove the bracket and enlarge the holes to the final size (9/16 in. for 58058, 11/16 in. for 30124). If they do not align, you adjust the 1/8 in. holes so they do align before enlarging them.
Yes. After drilling and before installing the frame brackets, you must paint all bare metal to prevent rust. This is required in both the 58058 and 30124 installation procedures.
Torque all 1/2 in. Grade 5 hardware to 72 ft-lbs (98 N-m). This applies to all bolts, nuts, and washers in the 58058 installation. The fasteners must be tightened in the following sequence: 1) torque the frame brackets to the truck frame, 2) reinstall the unassembled fifth wheel saddles/slider/goose, 3) torque the mounting rails to the frame brackets and bed.
Torque all 5/8 in. Grade 5 hardware to 150 ft-lbs (203 N-m). The fasteners must be tightened in the following sequence: 1) torque the frame brackets to the truck frame, 2) torque the mounting rails to the frame brackets.
For the 58058 kit: pilot holes are 1/8 in.; three rear holes are enlarged to 9/16 in.; two front bed holes are enlarged to 1-1/8 in. (top layer only); and two additional holes in the bed support are drilled to 9/16 in.
For the 30124 kit: pilot holes are 1/8 in.; holes are enlarged to 11/16 in.; and 1-1/8 in. holes are drilled in the bed with a hole saw.
The 58058 kit includes two tube spacers that are 2.75 in. long (installed in the forward holes) and two tube spacers that are 2.06 in. long (installed between the bed and frame bracket).
The 30124 kit includes two tube spacers that are 1-1/4 in. long, two tube spacers that are 4 in. long, and two spacers that are 1-1/2 x 5 x 5/16 in.
For the 58058 kit, the approximate cab-to-king-pin distance is 56 in. for an 8-foot bed and 36 in. for a 6-foot bed. The king pin should be centered over the axle centerline.
For the 30124 kit, the approximate cab-to-king-pin distance is 52 in. for an 8-foot bed and 32 in. for a 6-foot bed. The king pin should be centered over the axle centerline.
Tighten fasteners in this sequence: 1) torque the frame brackets to the truck frame, 2) reinstall the unassembled fifth wheel saddles/slider/goose, 3) torque the mounting rails to the frame brackets and bed. All 1/2 in. Grade 5 hardware should be torqued to 72 ft-lbs (98 N-m).
Tighten fasteners in this sequence: 1) torque the frame brackets to the truck frame, 2) torque the mounting rails to the frame brackets. All 5/8 in. Grade 5 hardware should be torqued to 150 ft-lbs (203 N-m).
Place the rear mounting rail in the bed of the truck. Using a tape measure, center the rail on the truck bed floor and position it the proper distance from the rear edge of the truck box. For an 8-foot bed, measure 28-1/4 in. from the back of the bed to the back of the rear rail. For a 6-foot bed, measure 26-1/4 in. See Figure 3 (diesel) or Figure 3A (gas) for the correct drilling locations.
Place the rear mounting rail in the box of the truck. Using a tape measure, center the rail between the weld seams on the length of the truck box floor and position it the proper distance from the rear edge of the truck box. For an 8-foot bed, measure 28-3/8 in. from the back of the bed to the back of the rear rail. For a 6-foot bed, measure 26-3/8 in. See Figure 6 (diesel) or Figure 6A (gas) for the correct drilling locations.
U-shaped spacers are placed between the rail and the bed (above or below depending on bed corrugation) to prevent the bed from collapsing when the bolts are tightened. They may need to be installed beneath the bed and above the frame bracket if you are drilling into the raised area of the bed corrugation.
Spacers are placed between the rail and the bed to prevent the bed from collapsing when the bolts are tightened. The 1-1/4 in. tube spacer is placed between the rail and the bed, and the 1-1/2 x 5 in. spacer is placed above or below the bed depending on bed corrugation. The spacer may need to be placed under the bed between the support and the bed if the corrugation is in a high position at the bolt junction.
For the 58058 kit: place the rear brackets on the inside of the frame. Install a u-bolt on each bracket; the u-bolt wraps around the outside of the frame, right behind the rear bed support. Loosely install 1/2 in. conical washers and hex nuts onto the ends of the u-bolts. For the 30124 kit: the procedure is the same, but the u-bolt wraps around the outside of the frame behind the rear bed support.
Place the front brackets on the outside of the frame (a portion will be under the bed support). Install a u-bolt on each bracket; the u-bolt wraps around the inside of the frame. Loosely install 1/2 in. conical washers and hex nuts onto the ends of the u-bolts. Important: the u-bolt on the driver side must be placed between the brake line and the frame. Improper placement may result in damage to the vehicle's braking system. Move the electric wiring harness out of the way.
For the driver side rear only, feed a 1-3/4 in. carriage bolt and a 1 x 3 in. block into position in the slot on the underside of the frame using a pull wire. There is a round hole in the inside of the frame that can be used to feed the hardware. Loosely fasten the carriage bolt with a 1/2 in. conical washer, lock washer, and hex nut.
Place the unassembled fifth wheel saddles/slider/goose into the already installed rear mounting rail. Position the second (front) mounting rail with the saddles/slider/goose by inserting the tabs into the mounting rail and pushing the mounting rail tight towards the other mounting rail. Ensure that the mounting rail is centered between the weld seams on the length of the truck box floor. This will position the mounting rail in the correct location and ensure that the fifth wheel will have a snug fit to the truck. If more than one hitch product will be used with the rails, both should be used at the same time to align the second rail.

Position the second (front) mounting rail with the saddles/slider/goose by inserting the tabs into the mounting rail and pushing the mounting rail tight towards the other mounting rail. Ensure that the mounting rail is centered between the weld seams on the length of the truck box floor. If more than one hitch product will be used with the rails, both should be used at the same time to align the second rail to ensure that one product does not compromise the fit of the other.
The front frame brackets should be positioned just rearward (58058 kit) or just rear (30124 kit) of the next bed support. For the 58058 kit, a portion of the frame brackets will be under the bed support.
Under no circumstances do we recommend exceeding the towing vehicle manufacturer's recommended vehicle towing capacity. Always measure the truck and trailer before installing the hitch to be sure that there is clearance at the cab and at the bumper to allow for turns.
When drilling holes, be aware of potential risks to vehicle components and make appropriate safeguards to protect them from damage. This is especially important because drilling may encounter fuel lines, brake lines, wiring, or other critical components beneath the truck bed and frame.
The u-bolt on the driver side must be placed between the brake line and the frame. Improper placement of the driver side u-bolt may result in damage to the vehicle's braking system. This is a critical safety issue that must be verified during installation.
After tightening all fasteners to the specified torque: 1) reinstall the wiring harness to the inside of the driver side frame (use a cable tie if necessary), 2) reinstall the spare tire, 3) reinstall the exhaust if it was lowered during installation. Verify that all fasteners are properly tightened and that the mounting rails are securely attached to the frame and bed.
Yes, the 50140 fits Dodge Ram 2500 diesel models from 2003–2012 (Standard, Quad, and Megacab). You must choose between the 58058 or 30124 rail kit; contact your supplier to confirm which is correct for your application.
You need wrenches (3/4, 7/8, 15/16 in.), drill bits (1/8, 9/56, 11/16 in.), a center punch, measuring tape, and a 1-1/8 in. hole saw. All fasteners are supplied in Kit 116629.
Yes, drilling is required. You must drill pilot holes, then enlarge them to final sizes (9/16 in. or 11/16 in. depending on kit) and drill 1-1/8 in. holes in the bed with a hole saw. When drilling, protect vehicle components from damage.
