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 M5 ISR 20K LEGS (part number 30926) are support legs for a 5th wheel hitch system rated for 20,000 lbs towing capacity with a maximum pin weight of 5,000 lbs. The legs attach to the M5 Center Section and provide vertical support for the hitch assembly when mounted on a truck. They must be used together with the M5 Head (part 30892) and M5 Center Section (part 30884).
The M5 ISR 20K LEGS are designed for installation on trucks with existing above-bed rails. The legs attach to the M5 Center Section, which then mounts to these rails using provided pins and spring clips. The manual does not specify which truck models or years are compatible. Contact the manufacturer at 1-800-632-3290 or consult a fitment database to confirm compatibility with your specific vehicle.
No. The M5 ISR 20K LEGS are designed specifically for installation with the M5 Head (part 30892) and M5 Center Section (part 30884). The legs attach to the center section structure and cannot function as a standalone product.
You will need an M24 wrench and a torque wrench. The M24 wrench is used to tighten the handle assembly on the head unit. The torque wrench is required to tighten the M16 hex-head bolts to the specified 220 ft-lb torque value.
The M5 ISR 20K LEGS (part 30926) include: 2 M5 ISR Legs, 4 M16 x 2 x 40mm CL10.9 hex-head bolts, 4 5/8-inch conical washers, 4 half-inch pins, and 4 spring clips. The legs also have 4 holes for anti-rattle accessories, which are sold separately.
Yes. The M5 ISR 20K LEGS come ready to install. No pre-assembly or preparation of the legs themselves is required before attachment to the center section.
A minimum of 6 inches of clearance is required between the truck bed rail and the bottom of the trailer. The legs must be attached at the same height on both sides of the unit. The M5 ISR 20K LEGS provide 4 inches of vertical adjustment to help achieve this clearance. For detailed guidance on matching the hitch, truck, and trailer, refer to the guidelines in the M5 Head and Center Section instruction sheet.
Using the 4 M16 x 2 x 40mm hex-head bolts, attach the legs to the center section structure by threading the bolts from the inside of the center section into the threaded portion of the legs. Finger-tighten the bolts initially until final adjustments are made. Make sure the collars on each leg are completely seated in the corresponding holes in the center section before final tightening.
Once the legs are attached to the center section and the unit is placed in the existing above-bed rails, use the provided half-inch pins to secure the assembly to the rails. Insert the pins through the alignment holes and secure each pin with a spring clip to prevent the pin from coming out. The spring clip must be used on all pins.
Each M16 hex-head bolt that connects the legs to the center section must be tightened to 220 ft-lb of torque. The bolts should be finger-tightened initially until final adjustments are made, then torqued to the final specification once the legs are pinned and securely held in the above-bed rails.
After tightening each M16 hex-head bolt to 220 ft-lb of torque, verify that the hitch is tight to the truck by lifting each side of the hitch. You must also verify that other components of your towing system do not reduce the overall tow rating of the hitch. Once these checks are complete, assemble the head to the center section per the instructions included with the M5 Center Section and Head.
The hitch system is rated for 20,000 lbs towing capacity with a maximum pin weight of 5,000 lbs. However, you must not exceed the towing vehicle manufacturer's recommended towing capacity or the lowest rated component of your system, whichever is lower.
Before any trip, verify that the pins and spring clips are undamaged and secure. Every 1,000 miles, check the M16 hex bolts that connect the center section to the legs to ensure they are still torqued to 220 ft-lb. For general maintenance of the entire 5th wheel hitch assembly, refer to the M5 Head and Center Section instruction sheet.
After tightening the M16 hex-head bolts to 220 ft-lb of torque, lift each side of the hitch to verify it is tight to the truck. The pins and spring clips must be secure and undamaged. Verify that other components of your towing system do not reduce the overall tow rating of the hitch.
The M5 ISR 20K LEGS provide 4 inches of vertical adjustment. This allows you to position the hitch at the correct height to maintain a minimum of 6 inches of clearance between the truck bed rail and the bottom of the trailer.
The M5 ISR 20K LEGS are designed for trucks with existing above-bed rails. The manual does not specify compatible vehicle models. Contact the manufacturer at 1-800-632-3290 or consult a fitment database for your specific truck.
You need an M24 wrench and a torque wrench. The torque wrench must be capable of measuring 220 ft-lb.
No drilling is required. The legs attach to the center section using existing threaded holes and are secured to the truck's above-bed rails using provided pins.
Tighten each M16 hex-head bolt to 220 ft-lb of torque. Check this torque every 1,000 miles during maintenance.
