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 56001 is designed for 2011 and later Chevrolet and GMC 2500/3500 pickup trucks with 6'6" or 8' bed lengths. Confirm your bed length before ordering, as the mounting rail positioning differs between the two.
You need Fastener Kit 56001F (supplied separately), ¾" and 15/16" wrenches, 1/8" and 9/16" drill bits, a center punch, and a measuring tape. The kit includes frame brackets, carriage bolts, washers, nuts, and pull wires. Mounting rail kit 30153 is sold separately.
No. Plastic bed liners must be cut away to provide metal-to-metal contact between the mounting rails and the truck bed. Spray-in bed liners are acceptable and do not need to be removed.
Yes. You must drill 1/8" pilot holes through the truck bed and frame, then enlarge them to 9/16". The manual warns that the fuel tank is located below the driver's side bed; take care not to damage it when drilling.
Torque all ½" nuts to 110 ft-lbs and all 5/8" nuts to 212 ft-lbs. All bolts and nuts are Grade 8 unless otherwise specified.
Do not exceed the towing vehicle manufacturer's recommended towing capacity. The mounting kit itself does not increase or change your vehicle's capacity.
The 56001 is a frame-mounted bracket system designed to support fifth-wheel hitches on 2011 and later Chevrolet and GMC 2500/3500 pickup trucks. It includes left and right frame brackets, carriage bolts, washers, nuts, and pull wires. The mounting rails (kit 30153) are sold separately. The kit provides the connection points between the truck frame and the fifth-wheel hitch assembly.
The 56001 is designed for both 6'6" and 8' bed pickup trucks. The mounting rail positioning differs between bed lengths: for a 6'6" bed, measure 24-1/4" from the rear edge of the truck box; for an 8' bed, measure 29" from the rear edge. Always measure your specific truck before installation.
No. The 56001 includes only the frame brackets and fasteners to attach them to the truck frame. The mounting rail kit 30153 must be purchased separately. The fasteners marked with an asterisk (*) in the parts list are supplied with kit 30153.
Always measure your truck and trailer before installation to ensure there is adequate clearance at the cab and bumper to allow for turns. This is especially important for short-bed trucks (between 6' and 8'), which may require an extended pin box, Reese® Sidewinder, or slider for additional clearance. Do not use a Sidewinder and slider together on the same installation.
Reese® recommends that the trailer be equipped with an extended pin box or Reese® Sidewinder to gain additional clearance. Alternatively, you can use one of the Reese® sliders for increased turning clearance during low-speed, non-highway maneuvering. Do not use a Sidewinder and slider together on the same installation. Consult the trailer manufacturer for available options.
1. Position the rear mounting rail in the truck bed, centered and at the correct distance from the rear edge (24-1/4" for 6'6" bed, 29" for 8' bed). 2. Mark and drill 1/8" pilot holes through the bed using the rail as a guide. 3. Temporarily position the frame brackets on the frame sides and check alignment. 4. Enlarge the 1/8" holes to 9/16". 5. Install the frame brackets using the pull-wire method: thread a 5/8" pull wire over a 5/8" x 2" carriage bolt, place a square hole spacer over the wire, insert the free end through the frame's access hole, pull the threaded bolt end through the mounting hole, position the bracket, remove the wire, and install the washer and nut. 6. Finger-tighten all nuts. 7. Repeat for the front rail. 8. Torque all ½" nuts to 110 ft-lbs and all 5/8" nuts to 212 ft-lbs.
The pull-wire method allows you to install carriage bolts through the truck frame's access hole without removing the frame brackets. Thread a 5/8" pull wire over a 5/8" x 2" carriage bolt, place a square hole spacer over the wire, insert the free end of the wire into the large access hole on the inside of the frame, and pull the threaded end of the bolt out through one of the mounting holes. Ensure the square hole plate is over the bolt and the square shank is in the square hole. Position the bracket over the bolt, remove the wire, install the washer and nut, and finger-tighten. Repeat for the other three bolts.
You need a 1/8" drill bit for pilot holes and a 9/16" drill bit for final holes. First, mark hole locations with a center punch and drill 1/8" pilot holes. After checking alignment with the frame brackets, enlarge the 1/8" holes to 9/16". For center bolt holes in the bed, drill directly to 9/16".
The fuel tank is located below the driver's side of the truck bed. When drilling holes through the bed, especially on the driver's side, take care not to damage the fuel tank. Use a center punch to mark hole locations precisely before drilling, and be aware of the tank's location relative to your drilling points.
The 56001 includes: 1 left frame bracket, 1 right frame bracket, 4 square hole plates, 4 5/8" serrated washers, 4 5/8-11 hex nuts, and 4 5/8-11 pull wires. Additional fasteners marked with an asterisk (½" x 2" carriage bolts, 5/16" spacers, ½" serrated washers, and ½" nuts) are supplied with the separate rail kit 30153.
The kit uses two sizes of carriage bolts: 5/8-11 x 2" bolts (4 supplied with the 56001 for frame bracket attachment) and ½" x 2" bolts (supplied with rail kit 30153 for rail-to-bracket attachment). All bolts and nuts are Grade 8 unless otherwise specified.
All ½" nuts must be torqued to 110 ft-lbs. This applies to the fasteners connecting the mounting rails to the frame brackets and the center bolt holes in the truck bed.
All 5/8" nuts must be torqued to 212 ft-lbs. This applies to the fasteners connecting the frame brackets to the truck frame.
Finger-tighten all nuts during the initial assembly steps. Only after all brackets and rails are positioned and aligned should you apply final torque: 110 ft-lbs for ½" nuts and 212 ft-lbs for 5/8" nuts.
Metal-to-metal contact is critical for proper installation. Use the supplied 5/16" thick U-shaped blocks between the frame bracket and the bottom of the bed, or between the mounting rails and the truck bed. These spacers ensure that the fasteners clamp metal directly to metal, not through any gap or liner material.
Center the rear mounting rail on the floor of the truck bed. Measure from the rail to the rear edge of the truck box: 24-1/4" for a 6'6" bed or 29" for an 8' bed. Use the first hole from the outside as shown in Figure 2. After installing the rear rail, position the front rail by inserting the tabs of the fifth-wheel support arches/slider/goose into the mounting rail and pushing the rail tight toward the rear rail. Ensure the front rail is centered on the bed.
If more than one hitch product will be used with the mounting rails, assemble both types at the same time to align the rear mounting rail. This ensures that one product does not compromise the fit of the other.
Do not exceed your vehicle manufacturer's recommended towing capacity. Always measure your truck and trailer before installation to ensure adequate clearance at the cab and bumper for turns. Be careful not to damage the fuel tank (located below the driver's side bed) when drilling. Use only the supplied Grade 8 bolts, nuts, and washers. Follow all torque specifications exactly. These instructions are guidelines; the installer and owner are responsible for proper installation.
After installation, verify that all fasteners are torqued to specification (110 ft-lbs for ½" nuts, 212 ft-lbs for 5/8" nuts), that the mounting rails are centered on the truck bed, and that the fifth-wheel hitch has a snug fit to the truck. Confirm that there is adequate clearance at the cab and bumper for turns with your trailer.
Reposition the 1/8" holes before enlarging them to 9/16". The manual explicitly states: "If not, re-position the 1/8" holes." Do not enlarge misaligned holes, as this will result in an improper fit. Drill new 1/8" holes in the correct location and verify alignment again before enlarging to 9/16".
Ensure that the 5/16" thick U-shaped blocks are properly positioned between the frame bracket and the truck bed to provide metal-to-metal contact. If the bed has contours or the liner has not been fully removed, the spacers may not bridge the gap. Verify that all fasteners are finger-tightened before final torquing, and that the square hole plates are correctly positioned over the carriage bolts.
Stop immediately and do not operate the vehicle. Contact a qualified fuel system technician or your vehicle dealer. Fuel tank damage is a serious safety hazard and requires professional repair. The manual warns: "On the driver's side of the vehicle the gas tank is located below the bed of the vehicle. When drilling holes through the bed be sure not to damage the fuel tank."
Loosen the fasteners (do not fully remove them) and reposition the rails so they are centered on the bed. Ensure that the rear rail is at the correct distance from the rear edge of the truck box (24-1/4" for 6'6" bed, 29" for 8' bed). For the front rail, push it tight toward the rear rail while keeping both centered. Once properly positioned, re-tighten all fasteners to the specified torque values.
Verify that the mounting rails are centered on the truck bed and that the front and rear rails are properly aligned and tightened. The manual states: "Ensure that the mounting rail is centered on the bed of the vehicle. This will position the rail in the correct location and ensure that the fifth wheel will have a snug fit to the truck." If the rails are properly positioned and torqued but the fit is still loose, the hitch product itself may be defective.
Ensure that the access hole is clear of obstructions and that you are inserting the free end of the pull wire (not the threaded end attached to the carriage bolt) into the hole. The wire should slide through smoothly. If the hole is blocked or the wire is kinked, straighten it and try again. If the hole is damaged or blocked, you may need to access the frame from a different angle or consult a qualified installer.
