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 RE50087 (Part #RE50087) is designed to fit the 2015-2020 Ford F-150.
The Reese Fifth Wheel Hitch Mounting System Custom Bracket RE50087 (Part #RE50087) 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 Bracket RE50087 (Part #RE50087) 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.
The Reese Fifth Wheel Hitch Mounting System Custom Bracket RE50087 (Part #RE50087) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The 50087 is a frame-mounted bracket kit designed to support a fifth wheel hitch on Ford F-150 trucks. It includes driver and passenger side frame brackets, spacer blocks, galvanic isolators, fasteners, and pull wires. The kit must be used with a separate rail kit (58058 or 30035) to complete the fifth wheel installation.
The 50087 is designed for Ford F-150 trucks with 5.5', 6.5', and 8' truck beds. The manual does not confirm compatibility with other F-150 model years or bed lengths. Before purchasing, visit www.ReeseProducts.com to verify your specific vehicle application and ensure you have the most recent installation instructions.
No. The manual explicitly states: "Do not install this product on or attempt to tow with a truck with a 5-1/2' bed unless a sidewinder pin box coupler has been installed on the trailer." If your trailer does not have a sidewinder pin box coupler, you cannot use this kit on a 5-1/2' bed truck.
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. Mounting rails may be installed on spray in liners." You must remove or cut away any drop-in plastic bed liner to expose the aluminum truck bed for proper installation.
Fastener Kit 50087F is required and contains all bolts, nuts, and washers for this kit. 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. All fasteners listed in the parts diagram are supplied with the 50087 kit. Additional fasteners for the rail kit (58058 or 30035) are supplied separately with that kit.
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 nuts (1/2" Grade 5), 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"). All other fasteners are supplied with the rail kit.
The manual states: "Lower and remove spare tire if extra room is needed." Removal is optional and depends on whether you need extra working space. If your truck has an inner plastic wheel well liner, you must remove it to access the frame.
Galvanic isolators prevent corrosion caused by contact between steel components (frame brackets, spacers, mounting rails) and the aluminum truck bed. Isolator strips (item 9) are placed on the bottom surface of each rail. Isolator squares (item 10) are placed on U-shaped spacers and at frame bracket mounting holes where they contact the truck bed. The manual emphasizes: "It is important that the galvanic isolator strips are installed correctly to avoid corrosion."
Using a measuring tape, center the rear mounting rail between the weld seams on the length of the truck box floor and position it at the proper distance from the rear edge of the truck bed (see Figure 2 for visual reference). The hitch centerline should be positioned approximately 1" forward of the axle centerline, and the rear mounting rail should be 28-3/4" from the rear edge of the bed for 5.5', 6.5', and 8' boxes.
First, drill pilot holes with a 1/8" drill bit at marked positions. After checking alignment with the frame brackets, enlarge these holes to 9/16". The manual warns: "When drilling holes be aware of potential risks to vehicle components and make appropriate safe guards to protect them from damage." After drilling through the bed, paint all bare metal to prevent corrosion.
Yes. You must drill pilot holes with a 1/8" bit, then enlarge them to 9/16" to mount the frame brackets to the truck frame. The manual requires you to mark positions with a center punch before drilling and to 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 torque the frame brackets to the truck frame. The manual specifies that all bolts and nuts are Grade 8 unless otherwise specified in the parts list.
Pull wires (item 12) are used to route fasteners through the truck frame to the mounting brackets. For the rear mounting hole, you insert the coiled end of the pull wire through the 1-1/2" diameter mounting hole on the frame side, attach a carriage bolt and block to it, push the hardware up into the frame through the large oval access hole, then use the other end of the pull wire to thread through the block and frame bracket. You gently pull on the pull wire to move the hardware into position in the frame bracket, then install the conical washer and nut.
Both use pull wires, but the rear mounting hole uses a 0.50" × 1.5" × 2" block (item 4), while the front mounting hole uses a circle block (item 11). For the front mounting hole, the square hole in the circle block must sit at the bottom of the mounting hole on the frame, and the circle block should fit inside the embossment in the truck frame. Both procedures end with installing a 1/2" conical washer and 1/2" nut and hand-tightening.
Install the 1/2" × 2" carriage bolts with U-shaped spacers (x2) positioned in the corrugation between the truck bed and the mounting rail, or between the bed and frame bracket. The 1/2"-13 × 2" hex head bolts may be used instead of carriage bolts on the outer rail attachment if carriage bolts are difficult to install. Each U-shaped spacer must have a 2" × 2" galvanic isolator square (item 10) placed on the side making contact with the truck bed. Attach washers and hex nuts on the bottom side of the frame bracket and tighten snug to keep the mounting rail from moving.
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 first rail. Ensure the second rail is centered between the weld seams on the truck box floor. If more than one hitch product will be used with the rails, install both at the same time to align the second rail and ensure one product does not compromise the fit of the other.
The manual states: "Under no circumstances do we recommend exceeding the towing vehicle manufacturers recommended vehicle towing capacity." You must verify your truck's towing capacity and never exceed it when using this hitch. Additionally, always measure the truck and trailer before installing the hitch to ensure clearance at the cab and bumper for turns.
After installation, verify that the 1/8" drilled holes align with the slots of the frame brackets before enlarging them to 9/16". Ensure all 1/2" hardware is torqued to 75 ft-lbs (mounting rails to frame brackets first, then frame brackets to truck frame). Check that the mounting rails are centered between the weld seams on the truck box floor. Verify clearance at the cab and bumper for turns. Replace the inner plastic wheel well liner and spare tire if removed. Paint any bare metal where holes were drilled through the bed.
The 50087 is a mounting kit only. You must purchase a separate rail kit (part number 58058 or 30035) which contains the actual fifth wheel mounting rails and additional fasteners. The 50087 provides the frame brackets and hardware to attach the rails to your truck frame.
The 50087 fits Ford F-150 trucks with 5.5', 6.5', and 8' beds. Do not use on 5-1/2' beds unless a sidewinder pin box coupler is installed on the trailer. Verify your specific application at www.ReeseProducts.com before purchasing.
You need Fastener Kit 50087F (included), wrenches (3/4", 7/8", 18mm), drill bits (1/8" and 9/16"), a center punch, and a measuring tape. All fasteners for the 50087 are supplied; additional fasteners for the rail kit come separately.
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 your vehicle manufacturer's recommended towing capacity. Always measure the truck and trailer before installation to ensure clearance at the cab and bumper for turns.
Stop and recheck the positioning of the mounting rail. The manual requires you to verify alignment in Step 6: "Check that the 1/8" drilled holes from step 4 align with the slots of the frame bracket (1) & (2)." If they do not align, reposition the rail and re-drill the pilot holes before enlarging them to 9/16". Do not proceed to enlarge misaligned holes.
The manual states: "The 1/2"-13 x 2" hex head bolts (5), may be used in place of the carriage bolts on the outer rail attachment if it is difficult to install carriage bolts." Use the hex head bolts (item 5) instead. Both fastener types must still be torqued to 75 ft-lbs.
The manual states: "It is important that the square hole in the circle block (11) sits at the bottom of the mounting hole on the frame as shown in Figure 1. The circle block (11) should fit inside embossment in truck frame." Verify that the square hole is positioned at the bottom of the mounting hole and that the block is fully inserted into the embossment. If it still does not fit, check that you are using the correct circle block (item 11) and not another block type.
The manual warns: "Contact between any steel components (frame mounting brackets, U-shaped spacers, mounting rails, etc.) and aluminum bed may cause corrosion." This occurs when galvanic isolators are missing or improperly installed. Ensure galvanic isolator strips (item 9) are on the bottom surface of each rail and galvanic isolator squares (item 10) are on U-shaped spacers and frame bracket mounting holes where they contact the bed. Repaint any areas where holes were drilled through the bed.
The manual requires that U-shaped spacers be tightened snug in Step 9 "to keep the mounting rail from moving." If the rail is still moving after installation, verify that all fasteners are properly tightened snug and then torqued to 75 ft-lbs in Step 11. Check that all U-shaped spacers are in place in the corrugations between the bed and rail, and that all washers and nuts are secure on the bottom side of the frame brackets.
