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 50085 kit is designed for RAM 3500 trucks. However, the kit is available in two configurations depending on which rail kit you use: one for 58058 or 30035 rails, and another for 30124 or 30095 rails. Verify which rail kit your truck requires before purchasing.
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. However, the mounting rails may be installed on spray-in liners, which do not need to be removed.
You will need: wrenches in ¾" and 15/16" sizes; drill bits in 1/8" and 9/16"; a 1-1/8" hole saw (for 10-bolt configuration) or 1/8", 11/16", and 1-1/8" hole saws (for 4-bolt configuration); a center punch; and a measuring tape. All fasteners are supplied with the kit.
The fastener kit 50085F includes: U-bolts (½-13 x 4-3/8" Grade 5), carriage bolts (½-13 x 4-½" or 5/8-11 x 6" depending on configuration), hex bolts (½-13 x 5" Grade 5), conical washers (½" or 5/8"), hex nuts (½-13 or 5/8-11 Grade 5), tube spacers, and block spacers (.25" x 1.5" x 2" or .313" x 2" x 1" depending on configuration). All bolts and nuts are Grade 5 unless otherwise specified. Use only the supplied fasteners for installation.
Not necessarily. However, the manual recommends lowering and removing the spare tire if extra room is needed for installation. If required, you may also need to remove the inner plastic wheel well liner and detach the exhaust hangers to allow access to the frame.
Before installation, detach the clips that fasten the electrical wire loom and brake lines to the inboard driver side of the frame. This prevents wires and brake lines from being trapped between the brackets and frame during installation. After installation, these will be reattached. If a plastic bed liner is present, it must be cut away to expose metal. Lower and remove the spare tire if extra room is needed.
Place the rear mounting rail in the truck bed and use a measuring tape to center it between the weld seams on the length of the truck bed floor. Position it at the proper distance from the rear edge of the truck bed as shown in Figure 2 (for 58058/30035 rails) or Figure 4 (for 30124/30095 rails). It is critical that the rail is centered side to side on the truck bed. The specific distances are 28-½" and 26-½" for 58058/30035 rails, or 28-¼" and 26-¼" for 30124/30095 rails.
Yes, drilling is required. First, mark and center punch hole locations as shown in the figures, then drill each position with a 1/8" drill bit. After temporarily positioning the frame brackets to verify alignment, enlarge the 1/8" holes: to 9/16" where no tube spacers are used (for 58058/30035 rails), or to 1-1/8" in two places for tube spacers and 11/16" for other holes (for 30124/30095 rails). Use a 1-1/8" hole saw to enlarge bed holes for tube spacers in rows 2 and 3. Important: use the hole saw only to cut through the bed, not the bed support. Paint all bare metal after drilling.
Torque specifications depend on the fastener size and rail configuration. For 58058/30035 rails: torque all ½" hardware to 75 ft-lbs (102 N·m). For 30124/30095 rails: torque all 5/8" hardware to 150 ft-lbs (204 N·m) and all ½" hardware to 75 ft-lbs (102 N·m). First torque the mounting rails to the frame brackets, then torque the frame brackets to the truck frame.
After fully installing the 50085 custom mounting brackets, tighten fasteners in this sequence: first torque the mounting rails to the frame brackets, then torque the frame brackets to the truck frame. Use the torque specifications for your rail configuration (75 ft-lbs for ½" hardware on 58058/30035 rails; 150 ft-lbs for 5/8" and 75 ft-lbs for ½" hardware on 30124/30095 rails).
Block spacers (.25" x 1.5" x 2" for 58058/30035 rails or .313" x 2" x 1" for 30124/30095 rails) are positioned in the corrugation between the truck bed and the mounting rail or between the bed and rear brackets. Their purpose is to eliminate crushing of the bed corrugation when fasteners are tightened.
Place the unassembled 5th wheel saddles/slider/goose into the already-installed rear mounting rail. Position the front mounting rail by inserting the tabs into the mounting rail and pushing the mounting rail tight towards the rear mounting rail. Ensure the front mounting rail is centered between the weld seams on the truck bed floor. This positions the rail correctly and ensures the 5th wheel has a snug fit. If using multiple hitch products with the rails, use both at the same time to align the rear rail and ensure one product does not compromise the fit of the other.
For 58058/30035 rails: use ½-13 x 2" carriage bolts (supplied with the rails) with .25" x 1.5" x 2" block spacers, ½" conical washers, and ½-13 hex nuts. For 30124/30095 rails: use 5/8-11 x 3" carriage bolts (supplied with the tube spacer) with block spacers, 5/8" conical washers, and 5/8" hex nuts. Block spacers are positioned in the corrugation between the bed and rail or between the bed and brackets.
For 58058/30035 rails: use ½-13 x 2" carriage bolts with .25" x 1.5" x 2" block spacers, ½" conical washers, and ½-13 hex nuts. For 30124/30095 rails: use 5/8-11 x 6" carriage bolts (item 8) with 4" tube spacers, 5/8" conical washers, and 5/8" hex nuts. Block spacers are positioned in the corrugation between the bed and rail or between the bed and front brackets.
Frame brackets (front and rear, driver and passenger sides) are attached to the truck frame using U-bolts (½-13 x 4-3/8" Grade 5), conical washers (½"), and hex nuts (½-13 Grade 5). Install these loosely first to allow for rail positioning. Ensure that electrical wires and brake lines are not trapped between the brackets/U-bolt and frame. Tighten to the specified torque (75 ft-lbs for ½" hardware) after the mounting rails are positioned and secured.
Under no circumstances should you exceed the towing vehicle manufacturer's recommended vehicle towing capacity. The 50085 kit is designed to work within the truck's factory specifications, not to increase towing capacity beyond what the manufacturer allows.
You should always measure the truck and trailer before installing the hitch to ensure there is adequate clearance at the cab and at the bumper to allow for turns. This prevents interference with the truck body during trailer operation and ensures safe towing.
After fully installing the 50085 custom mounting brackets and tightening all fasteners to the specified torque, reattach the electrical wire loom and brake lines to the frame (use the supplied cable tie if necessary). Reattach the exhaust hangers. If you removed the spare tire and inner plastic wheel well liner during installation, reinstall them.
Yes, the Reese 50085 Custom Quick Install Mounting Kit is designed for RAM 3500 trucks. It is available in two configurations: one for 58058/30035 rails and another for 30124/30095 rails. Verify your truck's rail kit before purchasing.
No, plastic bed liners must be cut away to provide metal-to-metal contact. Spray-in liners are acceptable and do not need to be removed.
You will need wrenches (¾" and 15/16"), drill bits (1/8" and 9/16"), a 1-1/8" hole saw (or 1/8", 11/16", and 1-1/8" for 4-bolt configuration), a center punch, and a measuring tape. All fasteners are supplied.
Yes. You must drill 1/8" pilot holes, then enlarge them to 9/16" or 11/16" depending on configuration. Use a 1-1/8" hole saw for tube spacer locations. Drill only through the bed, not the bed support.
For 58058/30035 rails: 75 ft-lbs (102 N·m) for all ½" hardware. For 30124/30095 rails: 150 ft-lbs (204 N·m) for 5/8" hardware and 75 ft-lbs (102 N·m) for ½" hardware. Torque mounting rails to frame brackets first, then frame brackets to truck frame.
Not necessarily, but it may be needed for extra room. You may also need to remove the inner plastic wheel well liner and detach exhaust hangers to access the frame.
Yes, always measure to ensure adequate clearance at the cab and bumper for turns. This prevents interference during trailer operation.
Ensure that the carriage bolts with block spacers and fasteners are tightened snug (not to final torque) to keep the mounting rail from moving. If the rail continues to move, verify that the block spacers are properly positioned in the corrugation between the bed and the mounting rail or between the bed and brackets. Block spacers are designed to eliminate crushing of bed corrugation and provide stability. Tighten the fasteners snug before proceeding to the next step.
After drilling 1/8" pilot holes, temporarily position the frame brackets on the frame and verify that the 1/8" drilled holes align with the slots of the frame bracket. If they do not align, remove the frame brackets and recheck your hole locations against the positioning figures (Figure 2 for 58058/30035 rails or Figure 4 for 30124/30095 rails). Ensure the mounting rail is centered between the weld seams on the truck bed floor. Re-mark and re-drill the holes as needed before enlarging them to final size.
The manual specifies that you must use the hole saw only to cut through the bed, not the bed support. If you have drilled through the bed support, you may have compromised the structural integrity of the mounting point. Do not proceed with installation. Contact the manufacturer or an authorized installer for guidance on whether the truck bed can be safely used or if repair is needed.
Verify that the mounting rails are properly centered between the weld seams on the truck bed floor. The manual states that it is critical that each rail is centered side to side on the truck bed. If the rails are not centered, the 5th wheel will not have a snug fit. Loosen the fasteners, reposition the rails to ensure they are centered, and retighten. If using multiple hitch products with the rails, ensure both are used at the same time to align the rails and prevent one product from compromising the fit of the other.
Block spacers are designed to prevent crushing of bed corrugation. Ensure that the block spacers (.25" x 1.5" x 2" for 58058/30035 rails or .313" x 2" x 1" for 30124/30095 rails) are properly positioned in the corrugation between the bed and the mounting rail or between the bed and the brackets before tightening fasteners. The block spacer should be located in the corrugation, not on flat surfaces. If corrugation is already crushed, loosen the fasteners, reposition the block spacers correctly, and retighten.
