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, Outboard RE56011 (Part #RE56011) fits 2003-2010 Dodge Ram 2500 models. The 2010 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, Outboard RE56011 (Part #RE56011) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
Yes, part 56011 is designed for 2003–2013 Dodge Ram 2500 trucks. However, it is compatible only with the 30153 REESE® Rails. The kit does not work with other rail systems. Confirm that your truck has the 30153 rails installed before purchasing.
Yes, the kit is compatible with both long-bed and short-bed configurations. The installation dimensions differ: long-bed mounting rails are positioned 30 1/8" from the rear edge of the truck box, while short-bed rails are positioned 28 1/8" from the rear edge. The manual provides separate hole-drilling positions for each bed length in Figure 3.
No, not without modification. Plastic bed liners must be cut away completely to expose the metal truck bed. The mounting rails require metal-to-metal contact with the truck frame and bed. Spray-in bed liners may be used, but you should consult the installer about the recommended curing time before installation.
Yes. On 6.5-foot truck boxes only, you must use a reciprocating saw to cut off an extension attached to the truck box support beams that straddles the frame. This extension is not a structural part of the truck box and is used only by the manufacturer during assembly. Cutting it away allows the frame brackets to mount properly to the outside of the truck frame. This step is not required for other bed lengths.
You will need: wrenches (3/4" and 10 mm), drill bits (1/8", 9/16", and 1 1/4" hole saw), a center punch, a measuring tape, and a reciprocating saw (for 6-foot bed trucks only). All fasteners are supplied with the kit; no additional bolts, nuts, or washers should be used.
The kit includes: 2 front straps (1.500" wide), 1 driver-side bracket, 1 passenger-side bracket, 8 lock washers (1/2" plated), 10 carriage bolts (1/2"-13×4.500" Grade 8), 8 hex nuts (1/2"-13 Grade 8), 1 cable tie (8.500"), 4 bushings (2.937"), 4 rear bushings (2.60" black), 2 rear straps (2.000" wide), and 2 bushings (2.773"). All other fasteners needed for the 30153 rails are supplied separately with that part number.
You may need to lower and remove the spare tire if extra room is needed to access the frame. You must also remove the inner plastic wheel well liner to allow access to the frame. After installation, reinstall the wheel well liner and spare tire.
You must: (1) remove the parking brake cable hanger from the driver-side frame and keep the hanger and bolts for reinstallation; (2) detach the two electrical harness hanger plugs from the inside driver-side frame just behind the fuel tank. These components are reinstalled later in the process.
The installation sequence is: (1) prepare the truck by removing the spare tire, wheel well liner, parking brake cable hanger, and electrical harness plugs; (2) for 6.5-foot beds, cut the box support extension; (3) position and mark the rear mounting rail holes; (4) drill pilot holes (1/8"), then enlarge to 9/16"; (5) loosely install the rear frame brackets with straps, bushings, bolts, and nuts; (6) install the rear mounting rail with U-shaped spacers and tighten snug; (7) position the front mounting rail with the hitch saddle/slider/goose; (8) repeat drilling steps for the front rail; (9) enlarge row 2 holes to 1 1/4"; (10) install front bushings and bolts; (11) torque all 1/2" fasteners to 110 ft-lbs in the specified sequence (rails to frame brackets first, then brackets to truck frame); (12) reinstall the parking brake cable hanger, ground wire, and electrical harness; (13) reinstall the wheel well liner and spare tire.
You drill three different hole sizes: (1) 1/8" pilot holes at all marked positions; (2) 9/16" holes for the rear mounting rail attachment points (rows 1, 3, and 4); (3) 1 1/4" holes in row 2 of the truck bed only (not the frame). The 1/8" holes are enlarged to 9/16" before the frame brackets are installed. The 1 1/4" holes are drilled only after the rear rail is secured.
All 1/2" hardware (bolts, nuts, and washers) must be torqued to 110 ft-lbs. The torque sequence is: (1) first torque the mounting rails to the frame brackets; (2) then torque the frame brackets to the truck frame. All bolts and nuts supplied with the kit are Grade 8 unless otherwise specified.
For long-bed trucks, the rear mounting rail is positioned 30 1/8" from the rear edge of the truck box. The rail should be centered between the weld seams on the truck box floor. The front mounting rail is positioned approximately 1 9/16" from the rear mounting rail. Refer to Figure 3 for the exact hole positions in rows 1–4.
For short-bed trucks, the rear mounting rail is positioned 28 1/8" from the rear edge of the truck box. The rail should be centered between the weld seams on the truck box floor. The front mounting rail is positioned approximately 1 7/16" from the rear mounting rail. Refer to Figure 3 for the exact hole positions in rows 1–4.
Leave fasteners loose during the initial assembly steps. Specifically: (1) loosely install the frame brackets in step 9; (2) tighten the mounting rail fasteners snug (not fully tight) in steps 12 and 16 to keep the rails from moving; (3) only after the front and rear rails are fully positioned and aligned, torque all 1/2" fasteners to 110 ft-lbs in the specified sequence in step 17.
The U-shaped spacers are positioned in the corrugation between the truck box and the mounting rail, or between the truck box and the side bracket. They prevent the truck bed corrugation from being crushed when the mounting rail fasteners are tightened. The spacers are used when installing the 1/2"-13 × 2 ½" carriage bolts for the rear rail.
Center the mounting rail between the weld seams on the length of the truck box floor. Use a measuring tape to verify the distance from the rear edge of the truck box matches the specification for your bed length (30 1/8" for long-bed, 28 1/8" for short-bed). When positioning the front rail with the hitch saddle/slider/goose, push the rail firmly toward the rear rail and verify it remains centered between the weld seams.
Yes, but both hitch products must be used at the same time during alignment to ensure proper fit. If more than one hitch product will be used with the rails, position both the front and rear mounting rails together during installation (step 13). This ensures that one product does not compromise the fit of the other.
Route the ground wire through the holes in the driver-side bracket (part 2). The wire is loosely installed in step 11 and then reinstalled and tightened in step 19 after all other fasteners are torqued.
After detaching the two electrical harness hanger plugs in step 3, secure the harness with the cable tie (part 7) supplied with the kit in step 20. This prevents the harness from moving or becoming damaged during operation.
Do not exceed the towing vehicle manufacturer's recommended towing capacity. Always measure the truck and trailer before installing the hitch to ensure there is adequate clearance at the cab and bumper to allow for turns. Installation and use of the product must be in accordance with the product instructions.
Check the mounting system bolt tightness once per year. Refer to the vehicle tow rating and the mounting bracket rating label for correct weight capacity. Save the warranty sheet and receipt for any future support.
Yes, the kit is covered by a Limited Lifetime Warranty. The warranty covers material defects in both material and workmanship, excluding ordinary wear and tear, provided that installation and use are in accordance with product instructions. The warranty is not transferable and applies only to the original consumer purchaser. For warranty claims, contact Cequent Performance Products, Inc. at 47912 Halyard Dr. Suite 100, Plymouth, MI 48170, or call 1-888-521-0510. Retain your purchase receipt and warranty sheet.
Yes, part 56011 is designed for 2003–2013 Dodge Ram 2500 trucks with 30153 REESE® Rails only. It fits both long-bed and short-bed configurations.
No. Plastic bed liners must be cut away to expose metal. Spray-in liners may be used with consultation on curing time.
Yes, on 6.5-foot beds only, use a reciprocating saw to cut off an extension attached to the truck box support beams. This is not required for other bed lengths.
You need: 3/4" and 10 mm wrenches, 1/8", 9/16", and 1 1/4" hole saw drill bits, a center punch, measuring tape, and a reciprocating saw (for 6-foot beds only).
Torque all 1/2" hardware to 110 ft-lbs. Torque the mounting rails to the frame brackets first, then torque the frame brackets to the truck frame.
No. Loosely install the frame brackets and snug the rail fasteners to keep them from moving. Only torque all 1/2" fasteners to 110 ft-lbs after the front and rear rails are fully positioned.
Do not exceed the towing vehicle manufacturer's recommended towing capacity. Always measure the truck and trailer before installing to ensure adequate clearance at the cab and bumper for turns.
Check mounting system bolt tightness once per year. Refer to the vehicle tow rating and mounting bracket rating label for weight capacity.
