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 Reese Fifth Wheel Hitch Mounting System Custom Bracket, Outboard RE56015 (Part #RE56015) fits 2019-2024 Chevrolet Silverado 1500 models. The 2024 model year is the last year covered by this part number. For newer models, check for an updated version.
The Reese Fifth Wheel Hitch Mounting System Custom Bracket, Outboard RE56015 (Part #RE56015) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The 56015 is designed for GMC/Chevy 1500 Pickup trucks, but specific years and models are listed on the manufacturer's website. Contact REESE® at 1-800-632-3290 or check their website to confirm your truck model is supported before purchasing.
No. The manual states: 'Do not install this product on or attempt to tow with a truck with a 5-1/2' bed unless a sidewinder pinbox coupler has been installed on the trailer.' If your truck has a 5-1/2' bed, you must have a sidewinder pinbox coupler on the trailer to use this kit.
No. The manual 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.' Spray-in bed liners are acceptable, but plastic liners must be removed or cut away in the installation area to ensure metal-to-metal contact between the mounting rails and truck bed.
The 56015 Custom Quick Install Mounting Kit is designed exclusively for use with the 30153 REESE® Rails. It cannot be used with other rail systems.
You will need: 3/4" wrenches, 1/8" and 9/16" drill bits, a center punch, a measuring tape, and a torque wrench with a 3/4" crows foot attachment. The fastener kit 56015F is also required.
The kit includes: 1 driver side frame bracket, 1 passenger side frame bracket, 4 half-inch U-bolts (Grade 5), 10 half-inch Grade 8 nuts, 10 half-inch conical washers, 2 carriage bolts (1/2"-13x1.75", Grade 8), 2 one-inch by 3-inch blocks, 2 one-inch by 2-inch blocks, 2 one-and-a-half-inch by 2-inch blocks, 2 three-and-a-half-inch by 1.5-inch blocks, and 1 pull wire. Additional hardware is supplied with the 30153 rail kit.
Yes. Step 3 of the installation instructions requires you to raise the rear of the vehicle and remove both rear tires before positioning the frame brackets.
The manual does not specify that the battery must be disconnected for this installation.
Yes. You must drill holes through the truck bed floor. First, use a center punch to mark hole locations based on the illustration on page 3, then drill each position with a 1/8" drill bit. After verifying alignment with the frame brackets, enlarge these holes to 9/16". The manual advises: 'When drilling holes through the bed be sure what is below the truck bed in those locations.'
According to the diagram on page 3, the bolt locations are 24-13/16" from the back edge of the truck bed and 46-3/4" apart (typical of both sides). These measurements apply to both 5.5' and 6.5' truck beds. Use a measuring tape and center punch to mark these positions before drilling.
Temporarily position the frame brackets on the sides of the frame, aligning the center hole in the bracket with the existing slot in the truck frame. The brackets must be tilted in at a 45° angle to clear the leading edge of the bed hem seam, then laid flat against the frame rail. Verify that the 1/8" drilled holes align with the slots in the frame brackets before proceeding.
Use the 3.5" x 1.5" block (Item 7) as a spacer behind the bracket. The U-bolt passes through the bottom hole, and the block sits between the bracket and the frame rail to ensure proper spacing and metal-to-metal contact.
Thread the supplied pull wire onto the supplied carriage bolt (Item 8), followed by the 1" x 3" block (Item 9). Pull both components through the center slot on the frame, ensuring the 1.5" x 2" block is placed between the frame and the frame bracket. Place the conical washer (Item 5) on the bolt and secure with a nut (Item 4). The pull wire must be used on both sides. Hand tighten initially; final torque specification is not provided in the manual.
Use U-shaped blocks between the frame bracket or mounting rails and the truck bed to ensure metal-to-metal contact. When installing the center bolt, use the 1" x 2" block (Item 10) on the bottom side of the bed floor.
Place the unassembled 5th wheel support arches/slider/goose into the already installed mounting rail. Position the rearward mounting rail 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 on the bed of the vehicle. If more than one hitch product will be used with the mounting rails, both types should be used at the same time to align the mounting rails properly.
Torque the 1/2" Grade 8 bolts to 110 ft-lbs (149 N·m).
Torque the 1/2" U-bolts to 75 ft-lbs (101 N·m).
Yes. The manual states: 'Be sure to tighten U-Bolts evenly!' Deflection in the bracket below the vehicle frame is expected and acceptable, but even tightening is required.
If the holes do not align properly, restart the installation at step 1 by adjusting the 1/8" holes on the truck bed. Do not enlarge the holes to 9/16" until all holes align correctly. Remove the frame brackets before enlarging any holes.
Yes. After drilling the 1/8" holes and verifying alignment, paint all bare metal before enlarging the holes to 9/16".
The manual states: 'Under no circumstances do we recommend exceeding the towing vehicle manufacturers recommended vehicle towing capacity, or the lowest rated component of your system.' You must not exceed either your vehicle manufacturer's recommended towing capacity or the lowest rated component in your towing system, whichever is lower.
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.' Verify clearance at both the cab and bumper to ensure the trailer can turn without interference.
The harness clip may need to be temporarily removed from the frame to install the U-bolt and bracket. The U-bolt must be routed between the frame and harness as shown in the diagrams on pages 4 and 5.
The 56015 is designed for GMC/Chevy 1500 Pickup trucks. Specific years and models are listed on the manufacturer's website. Not compatible with 5-1/2' beds unless a sidewinder pinbox coupler is installed on the trailer. Plastic bed liners must be cut away.
Required tools: 3/4" wrenches, 1/8" and 9/16" drill bits, center punch, measuring tape, and torque wrench with 3/4" crows foot. Required fastener kit: 56015F. All bolts and nuts are Grade 8 unless otherwise specified.
Yes. You must drill 1/8" holes through the truck bed floor at marked locations (24-13/16" from the back edge, 46-3/4" apart), then enlarge them to 9/16" after verifying alignment. Check what is below the bed before drilling.
Torque 1/2" Grade 8 bolts to 110 ft-lbs (149 N·m) and 1/2" U-bolts to 75 ft-lbs (101 N·m). Tighten U-bolts evenly. Center bolt torque is not specified in the manual.
Do not exceed your vehicle manufacturer's recommended towing capacity or the lowest rated component in your system. Always verify clearance at the cab and bumper before installation to allow for turns.
