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 RE50081 (Part #RE50081) fits 2004-2014 Ford F-150 models. The 2014 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 Bracket RE50081 (Part #RE50081) is designed to fit the 2004-2014 Ford F-150.
The Reese Fifth Wheel Hitch Mounting System Custom Bracket RE50081 (Part #RE50081) fits the following vehicles: 2004-2014 Ford F-150. Always verify your specific year, make, and model before ordering.
The Reese Fifth Wheel Hitch Mounting System Custom Bracket RE50081 (Part #RE50081) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The 50081 kit is designed for Ford F-150 models from 2004 to 2014. Verify your truck year falls within this range. The manual does not specify compatibility by cab style, drivetrain, or bed length beyond the restriction on 5-1/2' beds.
No. 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.
Yes. Plastic bed liners must be cut out of the way to provide metal-to-metal contact. Spray-in liners are acceptable and do not need to be removed.
Required tools: wrenches (3/4" and 15/16"), drill bits (1/8" and 9/16"), 3/4" socket, center punch, measuring tape, ratchet, and torque wrench.
Yes. You must drill holes using a 1/8" bit first, then enlarge them to 9/16" for 58058 rails or 11/16" for 30124 rails. When drilling, be aware of potential risks to vehicle components above and below the truck bed and take appropriate safeguards to protect them from damage.
Torque all 1/2" hardware to 72 ft-lbs. First torque the mounting rails to the frame brackets, then torque the frame brackets to the truck frame.
The 50081 kit includes: driver and passenger side brackets, hex nuts (1/2-13 Grade 5), conical washers (1/2"), spacers (1/4" x 1-1/2" x 2.00" and 1/4" x 1.00" x 2.00"), carriage bolts (1/2-13 x 1.50"), and washers (.835" OD and .970" OD). U-shaped spacers, carriage bolts, hex nuts, and conical tooth washers for the mounting rails are supplied separately with the 58058 or 30035 rail kit.
Yes. Lower and remove the spare tire before beginning installation. Reinstall it after the kit is fully installed.
Yes. Remove the axle bumper bolt (F), axle bumper (E), and multi-thread U-nut (D) from the underside of the frame on both driver and passenger sides. Keep these parts and reinstall them after the mounting brackets are installed.
The 50081 is a custom quick install mounting kit that attaches fifth wheel mounting rails (specifically the 58058 REESE® fifth wheel mounting rails) to the frame and bed of a Ford F-150 truck (2004-2014). It provides the structural connection between the truck and the fifth wheel hitch system.
The 50081 kit is designed for the 58058 REESE® fifth wheel mounting rails. The manual also mentions that 30124 rails can be installed, requiring 11/16" holes instead of 9/16". 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 and ensure proper fit.
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. This ensures that one product does not compromise the fit of the other.
Place the mounting rail in the truck bed and use a measuring tape 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 illustrated in the manual (approximately 2-1/4" from the rear edge, with the rear edge of the rear rail at 28-11/16" from the rear edge of the truck bed for all bed lengths). Repeat for the second rail, ensuring both rails are centered between the weld seams.
After fully installing the custom attachment brackets, tighten fasteners in this sequence: (1) torque all 1/2" hardware to 72 ft-lbs; (2) first torque the mounting rails to the frame brackets; (3) then torque the frame brackets to the truck frame.
Starting with the front mounting hole: (1) insert the head of the bolt leader through the 1-inch diameter mounting hole on the side of the truck frame and out through the 1-inch square access hole in the bottom of the frame; (2) slide the 1-inch washer (item 7) over the head of the bolt leader; (3) slide the spacer (item 6) over the head of the bolt leader and attach the 1/2 x 1-1/2" bolt (item 2); (4) push the hardware up into the frame through the 1-inch square hole; (5) with the other end of the bolt leader, thread it through the back side of the frame bracket and gently pull on the end so the hardware moves through the frame and into position; (6) rotate the frame bracket away from the frame slightly and verify the 1-inch bushing has engaged the frame properly; (7) install the 1/2-inch lock washer (item 4) and 1/2-inch nut (item 3), hand tighten only. Repeat for the rear hole using the 7/8-inch washer (item 8).
After enlarging the drilled holes to 9/16" (for 58058 rails) or 11/16" (for 30124 rails), reposition the mounting rail over the holes. Install 1/2" x 2-inch carriage bolts with the U-shaped spacer located in the corrugation between the box and the mounting rail to ensure metal-to-metal contact. Attach with spacers (item 5), washers (item 4), and hex nuts (item 3) as illustrated, and tighten snug to keep the mounting rail from moving.
First, drill 1/8" pilot holes. Then enlarge them to 9/16" if installing 58058 rails, or 11/16" if installing 30124 rails. The frame brackets use 1-inch diameter mounting holes on the side of the truck frame and 1-inch square access holes in the bottom of the frame.
After drilling the 1/8" pilot holes, check that they align with the slots of the frame bracket before enlarging them. This ensures proper positioning before the final hole size is drilled.
All bolts and nuts are Grade 8 unless otherwise specified. The hex nuts (item 3) are specifically Grade 5.
Yes. Always measure the truck and trailer before installing the hitch to ensure there is clearance at the cab and at the bumper to allow for turns. This is the responsibility of the installer and owner.
Do not exceed the towing vehicle manufacturer's recommended vehicle towing capacity. Refer to the mounting bracket rating label for the correct towing capacity of your specific installation.
Check mounting system bolt tightness once per year.
When installing the frame brackets in step 5, the 1/2-inch lock washer and 1/2-inch nut should be tightened by hand only, not with tools. Final torquing to 72 ft-lbs occurs later in step 13 after all brackets and rails are positioned.
The U-shaped spacer is located in the corrugation between the truck box and the mounting rail. It ensures metal-to-metal contact between the rail and the truck bed, which is critical for proper load distribution and structural integrity.
Place the unassembled fifth wheel saddles/slider/goose into the already-installed first mounting rail. Position the second mounting rail with the saddles/slider/goose by inserting the tabs into the mounting rail and pushing the mounting rail tight towards the other mounting rail. Ensure the second rail is centered between the weld seams on the length of the truck box floor. This positions the rail correctly and ensures the fifth wheel has a snug fit to the truck.
The manual references the 50081F fastener kit but does not provide a separate detailed list of its contents. The fasteners included in the 50081 kit itself are listed in the parts table on pages 4-5.
Yes. Mounting rails may be installed on spray-in liners. However, plastic bed liners must be cut out of the way to provide metal-to-metal contact.
When installing the 1/2" x 2-inch carriage bolts in step 9, tighten them snug to keep the mounting rail from moving. This is a preliminary tightening before the final torque specification of 72 ft-lbs is applied in step 13.
The kit includes: conical washers (1/2"), a 1-inch washer (item 7, .970" OD x .531" ID x .105" thick), a 7/8-inch washer (item 8, .835" OD x .531" ID x .105" thick), and conical tooth washers (supplied with the 58058 or 30035 rail kit).
The kit includes two types of spacers: (1) 1/4" x 1-1/2" x 2.00" spacers (item 5, qty 8) and (2) 1/4" x 1.00" x 2.00" spacers (item 6, qty 4). Additionally, U-shaped spacers are supplied with the 58058 or 30035 rail kit.
The bolt leader is a tool used to guide the fasteners through the frame bracket mounting holes. It is inserted through the 1-inch diameter mounting hole on the side of the truck frame and out through the 1-inch square access hole in the bottom of the frame, allowing the hardware to be positioned correctly inside the frame before final assembly.
After threading the bolt leader through the back side of the frame bracket and pulling the hardware into position, rotate the frame bracket away from the frame slightly and look to ensure the 1-inch bushing has engaged the frame properly before installing the lock washer and nut.
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. This ensures that one product does not compromise the fit of the other.
