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 Install Kit RE50087-58 (Part #RE50087-58) fits the following vehicles: 2015-2020 Ford F-150. Always verify your specific year, make, and model before ordering.
The Reese Fifth Wheel Hitch Mounting System Custom Install Kit RE50087-58 (Part #RE50087-58) fits 2015-2020 Ford F-150 models. The 2020 model year is the last year covered by this part number. For newer models, check for an updated version.
Yes, the Reese Fifth Wheel Hitch Mounting System Custom Install Kit RE50087-58 (Part #RE50087-58) is designed to fit the 2015-2020 Ford F-150.
The Reese Fifth Wheel Hitch Mounting System Custom Install Kit RE50087-58 (Part #RE50087-58) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The kit is designed for Ford F-150 trucks with 5.5', 6.5', and 8' beds. However, do not install this product on a truck with a 5.5' bed unless a sidewinder pin box coupler has been installed on the trailer. The kit is not recommended for 5.5' beds without this specific trailer equipment.
No. Plastic bed liners must be cut out of the way 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. 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. Mounting rails may be installed on spray in liners.'
You need fastener kit 50087F, which is required and must be ordered separately if not included. All fasteners listed in the kit are supplied with the 50087. Other fasteners mentioned in the instructions are supplied with rail kit 58058 or 30035.
Required tools are: wrenches in 3/4", 7/8", and 18mm sizes; drill bits in 1/8" and 9/16" sizes; a center punch; and a measuring tape. These are the minimum tools needed to complete the installation.
The spare tire should be lowered and removed if extra room is needed for installation. If your truck is equipped with an inner plastic wheel well liner, you must remove it to allow access to the frame. Whether you remove the spare tire depends on your working space and comfort level.
Using a measuring tape, center the rear mounting rail between the weld seams on the length of the truck bed floor and position it at the proper distance from the rear edge of the truck bed, as shown in Figure 2. The hitch centerline should be positioned approximately 1" forward of the axle centerline, and the rail should be located 28-3/4" from the bed edge for 5.5', 6.5', and 8' boxes.
Yes, drilling is required. You must drill two sets of holes: first with a 1/8" drill bit to mark positions, then enlarge those holes to 9/16". When drilling, be aware of potential risks to vehicle components and take appropriate safeguards to protect them from damage. After drilling through the bed, paint all bare metal to prevent corrosion.
All 1/2" hardware must be torqued to 75 ft-lbs. Torque the mounting rails to the frame brackets first, then torque the frame brackets to the truck frame. This two-stage torquing sequence is important for proper installation.
Do not exceed the towing vehicle manufacturer's recommended vehicle towing capacity. The kit is designed to work within the truck's factory specifications, and exceeding those limits can result in unsafe operation and potential damage.
Galvanic isolators prevent corrosion between steel components (frame brackets, U-shaped spacers, mounting rails) and the aluminum truck bed. Contact between these dissimilar metals without isolation causes corrosion. The kit includes galvanic isolator strips (9) for the bottom of the rails and galvanic isolator squares (10) for mounting points. These must be placed on surfaces that will contact the truck bed, and any bare metal created by drilling must be repainted.
After installation, measure your truck and trailer to verify there is adequate clearance at the cab and at the bumper to allow for turns. This is critical for safe operation and must be done before towing. Additionally, ensure all 1/2" hardware has been torqued to 75 ft-lbs and that the mounting rails are centered between the weld seams on the truck bed floor.
The kit includes: 1 driver bracket, 1 passenger bracket, 2 blocks (0.50" × 1.5" × 2"), 2 blocks (0.25" × 1.5" × 3"), 8 hex bolts (1/2"-13 × 2" Grade 5), 4 carriage bolts (1/2"-13 × 2" Grade 5), 4 conical washers (1/2"), 4 Grade 5 nuts (1/2"), 4 galvanic isolator strips, 18 galvanic isolator squares, 2 circle blocks, 4 pull wires (1/2"-13), and 20 U-shaped spacers (0.1875" × 1" × 2"). The fastener kit 50087F is required separately.
The pull wire (part 12) is used to guide hardware through the truck frame to the mounting brackets. You insert the coiled end of the pull wire through the frame's mounting hole, attach a block and carriage bolt to it, push the hardware up into the frame, then use the other end of the pull wire to thread through the block and frame bracket. By gently pulling on the pull wire, you guide the hardware through the frame and into position on the bracket.
The rear mounting hole uses a block (part 4, 0.50" × 1.5" × 2") with the pull wire and carriage bolt. The front mounting hole uses a circle block (part 11) instead. The circle block has a square hole that must sit at the bottom of the mounting hole on the frame and fit inside the embossment in the truck frame. Both use the same pull wire technique but with different block components.
Place the unassembled fifth wheel legs/slider/goose into the already-installed first mounting rail. Position the second mounting rail by inserting its tabs into the first rail and pushing it tight toward the other rail. Ensure the second rail is centered between the weld seams on the truck bed floor. If more than one hitch product will be used with the rails, install both at the same time to align the second rail correctly and ensure one product does not compromise the fit of the other.
U-shaped spacers (part 13) are positioned in the corrugation between the truck bed and the mounting rail, or between the bed and frame bracket. They prevent crushing the bed corrugation when the carriage bolts are tightened. Each U-shaped spacer must have a 2" × 2" galvanic isolator square (part 10) placed on the side that makes contact with the truck bed to prevent corrosion.
Yes, but only in specific situations. The 1/2"-13 × 2" hex head bolts (part 5) may be used in place of carriage bolts on the outer rail attachment if it is difficult to install carriage bolts. However, carriage bolts are the standard fastener and should be used whenever possible.
The kit fits Ford F-150 trucks with 5.5', 6.5', and 8' beds. On 5.5' beds, a sidewinder pin box coupler must be installed on the trailer. Plastic bed liners must be cut away; spray-in liners are acceptable.
You need fastener kit 50087F. Tools required: 3/4", 7/8", and 18mm wrenches; 1/8" and 9/16" drill bits; center punch; measuring tape. Drilling is required.
Yes. You must drill with a 1/8" bit, then enlarge holes to 9/16". Paint all bare metal after drilling to prevent corrosion.
All 1/2" hardware must be torqued to 75 ft-lbs. Torque the mounting rails to the frame brackets first, then the frame brackets to the truck frame.
Do not exceed the vehicle manufacturer's recommended towing capacity. Measure truck and trailer before installation to verify clearance at cab and bumper for turns.
Galvanic isolators prevent corrosion between steel components and the aluminum truck bed. They must be installed on all surfaces that contact the bed. Paint all bare metal created by drilling.
Verify clearance at the cab and bumper for turns with your truck and trailer. Confirm all 1/2" hardware is torqued to 75 ft-lbs. Ensure mounting rails are centered between bed weld seams.
Stop and recheck your work. In Step 6, you must verify that the 1/8" drilled holes align with the slots of the frame brackets (1) and (2) before enlarging them to 9/16". If they do not align, the rail positioning is incorrect. Reposition the rail and re-mark the holes using the center punch, then drill new 1/8" holes in the correct locations. Do not enlarge misaligned holes.
The square hole in the circle block (11) must sit at the bottom of the mounting hole on the frame, and the circle block must fit inside the embossment in the truck frame. If it does not fit, verify that the hole is drilled in the correct location and that the circle block is oriented correctly with the square hole facing downward into the frame embossment. Ensure the pull wire is positioned correctly to guide the block into place.
Corrosion occurs when steel components contact the aluminum truck bed without galvanic isolation. This happens if: (1) galvanic isolator strips (9) were not placed on the bottom surface of the rails, (2) galvanic isolator squares (10) were not placed at mounting points where U-shaped spacers contact the bed, (3) paint was damaged on the brackets, or (4) bare metal created by drilling was not repainted. To prevent further corrosion, remove the affected components, clean the area, apply galvanic isolators and paint, then reinstall.
In Step 9, the carriage bolts with U-shaped spacers must be tightened snug to keep the mounting rail from moving before final torquing. If the rail is still moving after snug tightening, verify that: (1) all bolts are present and properly seated, (2) the U-shaped spacers are correctly positioned in the bed corrugation, (3) the rail is centered between the weld seams on the truck bed floor. Then torque all 1/2" hardware to 75 ft-lbs in the correct sequence (rails to brackets first, then brackets to frame).
