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.

The 50054 is a custom mounting bracket kit designed to attach fifth wheel hitch rails to a RAM 2500 truck bed. It provides the frame brackets and fasteners needed to secure either 10-bolt rails (58058 or 30035) or 4-bolt rails (30124 or 30095) to the truck frame. The kit does not include the rails themselves; those are purchased separately.
The 50054 is designed for RAM 2500 trucks. The manual covers two configurations: 10-bolt kits for use with 58058 or 30035 rails, and 4-bolt kits for use with 30124 or 30095 rails. The manual notes possible variations in bed location and sills, so you should verify your specific truck configuration and rail type before purchasing. Always measure your truck and trailer before installation to ensure clearance at the cab and bumper for turns.
No. The manual explicitly states: "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." Mounting rails may be installed on spray-in liners, but plastic drop-in liners must be removed or cut away in the mounting areas to allow direct metal-to-metal contact between the brackets and the truck bed.
For the 10-bolt kit, you will need: wrenches in 3/4", 7/8", and 18mm sizes; drill bits in 1/8", 9/16", and a 1-1/8" hole saw; a center punch; and a measuring tape. For the 4-bolt kit, you will need: wrenches in 3/4", 7/8", and 18mm sizes; drill bits in 5/8" and 1-1/8" hole saw; a center punch; and a measuring tape. A torque wrench is also required for final tightening.
The 50054 kit includes fasteners to attach the custom brackets to the truck frame. However, the manual states: "All of the fasteners listed are supplied with this kit, all other mentioned fasteners are supplied with rail kit 58058" (for 10-bolt) or "rail kit 30124" (for 4-bolt). This means the carriage bolts and other fasteners that attach the mounting rails to the brackets come with the separate rail kit, not the 50054 kit.
The manual states: "Lower and remove spare tire if extra room is needed." This is optional, not required. However, removing the spare tire may make installation easier by providing better access to the frame. The manual also recommends removing the inner plastic wheel well liner to allow access to the frame.
The manual does not mention disconnecting the battery. However, the manual does require detaching the electrical wire loom and brake lines from the inside driver side of the frame before installation. No battery disconnection is specified.
Yes, drilling is required. For the 10-bolt kit, you must drill holes using a 1/8" bit initially, then enlarge them to 9/16" (in row 1) and 1-1/8" (in row 2, bed corrugations only). For the 4-bolt kit, you drill 1/8" holes and enlarge them to 1-1/8". The drilling goes through the truck bed and bed sill. The manual warns to protect the fuel tank, filler tubes, brake lines, and wire harness during drilling by placing metal between the box floor and components at risk.
Yes. The installation requires drilling through the truck bed and bed sill. These holes are permanent modifications to the vehicle. The manual states that all bare metal must be painted after drilling to prevent rust.
For the 10-bolt kit: Torque all 1/2" hardware to 75 ft-lbs (102 N·M) and all M12 hardware to 92 ft-lbs (125 N·M). For the 4-bolt kit: Torque all 5/8" hardware to 150 ft-lbs (204 N·M) and all M12 hardware to 92 ft-lbs (125 N·M). First torque the mounting rails to the frame brackets, then torque the frame brackets to the truck frame.
The 10-bolt kit includes: 8× M12-40MM-1.5" CL 10.9 bolts (for frame brackets); 2× 1/2"-13 X 4.5" carriage bolts (supplied with this kit); 2× 1/2"-13 X 2" Grade 5 hex head bolts (supplied with this kit); 8× 1/2" conical washers; 4× 0.25" X 1" X 3" block spacers; and 2× tube spacers. Additional 1/2"-13 X 2" carriage bolts come with the rail kit (58058 or 30035).
The 4-bolt kit includes: 8× M12-40MM-1.5" CL 10.9 bolts (for frame brackets); 2× 5/8"-11 X 3.5" hex head bolts (supplied with this kit); 2× 5/8"-11 X 2.5" carriage bolts (supplied with rail kit); 8× 1/2" conical washers; and 5/8" conical washers and nuts (supplied with rail kit). The kit also includes a 0.657" X 1.271" tube spacer and block spacers.
Place the rear mounting rail in the truck bed and use a tape measure to center it between the weld seams on the length of the truck box floor. Position it at the proper distance from the rear edge of the truck box as shown in Figure 2 (for 10-bolt with 58058/30035 rails) or Figure 4 (for 4-bolt with 30124/30095 rails). It is critical that the rail is centered side to side on the truck bed. The manual provides specific distances: 28-3/16" from the rear edge for 10-bolt kits and 25-11/16" for 4-bolt kits.
Block spacers (0.25" X 1" X 3") are placed in the corrugation between the truck box and the mounting rail or between the box and frame brackets. Their purpose is to eliminate crushing of the bed corrugation and to ensure metal-to-metal contact. The manual states: "Note the block spacer is to eliminate crushing bed corrugation."
The manual specifies a two-stage tightening process. First, install fasteners "snug" (hand-tight) to keep the mounting rail from moving while you position and align the other components. After fully installing all custom mounting brackets, tighten the fasteners in sequence: first torque the mounting rails to the frame brackets, then torque the frame brackets to the truck frame. Use the specified torque values for 1/2" hardware (75 ft-lbs for 10-bolt) or 5/8" hardware (150 ft-lbs for 4-bolt), and M12 hardware (92 ft-lbs for both).
After installing the rear mounting rail, place the unassembled fifth wheel saddles/slider/goose into the rear rail. Then position the front mounting rail by inserting the tabs into the mounting rail and pushing it tight towards the rear rail. Ensure the front rail is centered between the weld seams on the truck bed floor. The manual states: "This will position the mounting rail in the correct location and ensure that the 5th 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.
After fully installing and torquing all fasteners, reinstall the electrical wire loom and brake lines that were detached from the driver side of the frame. Replace the inner plastic wheel well liner if it was removed. Reinstall the spare tire if it was removed. The manual also recommends checking mounting system bolt tightness once per year.
The manual states: "Under no circumstances do we recommend exceeding the towing vehicle manufacturers recommended vehicle towing capacity." You must refer to your RAM 2500's owner manual or manufacturer specifications for the maximum towing capacity and ensure your trailer weight does not exceed that limit.
Yes. The manual states: "Always measure truck and trailer before installing hitch to be sure that there is clearance at the cab and at the bumper to allow for turns." This is important to ensure the hitch and fifth wheel do not interfere with the truck cab or bumper during turning.
The manual recommends checking mounting system bolt tightness once per year. This helps ensure the fasteners remain secure and the installation remains safe.
The 50054 is designed for RAM 2500 trucks and comes in two versions: 10-bolt (for 58058/30035 rails) and 4-bolt (for 30124/30095 rails). Verify your truck configuration and rail type before purchasing. Always measure your truck and trailer to ensure clearance at the cab and bumper.
The 50054 includes fasteners to attach brackets to the frame (M12 bolts, conical washers, block spacers, and tube spacers). Carriage bolts and other fasteners that attach the rails to the brackets come with the separate rail kit (58058, 30035, 30124, or 30095), not the 50054.
Yes. You must drill holes through the truck bed and bed sill. For 10-bolt kits, drill 1/8" holes and enlarge to 9/16" and 1-1/8". For 4-bolt kits, drill 1/8" holes and enlarge to 1-1/8". Protect fuel tank, filler tubes, brake lines, and wiring during drilling.
For 10-bolt kits: 1/2" hardware to 75 ft-lbs (102 N·M), M12 hardware to 92 ft-lbs (125 N·M). For 4-bolt kits: 5/8" hardware to 150 ft-lbs (204 N·M), M12 hardware to 92 ft-lbs (125 N·M). Torque mounting rails to frame brackets first, then frame brackets to truck frame.
No. Plastic bed liners must be cut away to provide metal-to-metal contact. Spray-in liners are acceptable. Always measure truck and trailer before installation to verify clearance at cab and bumper.
Check mounting system bolt tightness once per year to ensure the installation remains secure.
