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 hitch is rated for 32,000 lbs towing capacity with a maximum pin weight of 6,400 lbs. You must not exceed your towing vehicle manufacturer's recommended towing capacity, whichever is lower.
The M5 Head & Center Section is designed for use with M5 mounting legs, which are sold separately. Leg assembly instructions are included with the leg units. The center section has 3 possible attachment locations providing 4" of overall height adjustment.
A minimum of 6" clearance must be maintained between the truck bed rail and the bottom of the trailer. The center section has 3 possible attachment locations with 4" of overall adjustment to achieve this clearance.
Fastener kit 30892F is required for installation. The kit includes bolts, nuts and washers for the center section attachment. Additional fasteners for leg assembly are supplied separately with the leg units.
Required tools include: M13 and M24 sockets and wrenches, a torque wrench, and a grease needle (typically available at auto parts stores). A 7/16" socket is needed if adjusting head springs for added cab clearance.
The package includes: 1 assembly head unit, 1 handle, 2 pull pins (½"), 2 spring clips, 2 M8 carriage bolts, 2 M8 lock washers, 2 M8 nuts, and 1 center section (30932). Leg assembly fasteners are supplied separately with leg units.
Slide the tube over the bar and securely tighten using M8 carriage bolts, lock washers and nuts with an M13 wrench. The handle should be snug when properly assembled.
1. Apply grease to the pivot area (see maintenance section, figure 9). 2. Place the head unit on top of the center section, avoiding pinch points. 3. Insert the pull pin as shown in figure 6 and secure with spring clips on both sides. 4. Inspect through the sight holes on top of the head pan to confirm clips are assembled correctly.
Every use: Apply grease to the skid plate surface and to the 5th wheel jaw and/or kingpin on the trailer. Annually or as required: Apply grease via the grease fitting on top of the unit using a grease needle, apply spray white lithium grease to internal mechanisms and rotate the handle to distribute, and grease pivot assemblies with a grease gun with needle adapter. The unit comes pre-greased from the factory.
Yes, plastic lube plates can be used to avoid messy grease. The plate must not exceed 3/16" in thickness to ensure the hitch works properly. REESE 5th Wheel Lube Plate #83001 is recommended.
The pivot assembly resistance is preset at the factory. If the head pivots and makes noise when the trailer is not attached, tighten the pivot bolt 1/2 turn at a time, with a maximum of 2 full turns. Access the pivot bolt and nut through the logo/load rating slot using an open-end wrench (see figure 9B).
Ready-to-Receive Position: Used when delivered, when hitch is not in use, when coupling to trailer, and after uncoupling. Handle is pulled out so holes do not align for bail pin, and indicator shows RED. Locked Position: Used when coupled to trailer. Handle holes align for bail pin insertion and indicator shows GREEN. Unhitching Position: Used when unhitching the trailer. Handle is pulled out and rotated toward the cab, and indicator shows RED.
1. Ensure 5th wheel height is correct per leg installation instructions. 2. Verify truck and trailer are in position: 5th wheel secured, tailgate lowered if necessary, blocks firmly against trailer wheels, pin box at correct height (bottom of pin box aligned with top of skid plate ramp ±1 inch), and head in Ready-to-Receive position. 3. Back truck slowly into trailer so kingpin and 5th wheel funnel align; hitch latches automatically when fully backed in and indicator shows 100% green. 4. Perform pull test: with trailer wheels blocked, landing gears on ground, and trailer brake on, try to pull trailer forward slowly. If properly hitched, proceed; if not, repeat steps 1-3. 5. Insert bail pin into lock hole or use lock for added security. 6. Connect electrical and breakaway switch cables. 7. Remove chocks/blocks and lift trailer jacks.
If the jaw does not close when fully backed into the trailer, pull the truck slowly forward to remove load on the jaw. The handle will then fully latch.
1. Ensure trailer is secure: blocks firmly against trailer wheels and landing gears lowered and firmly on ground. 2. Prepare truck: lower tailgate as necessary and disconnect electrical and breakaway switch cables. 3. Ensure no person or vehicle is in the vicinity of truck or trailer, as they may shift during unhitching. 4. Remove bail pin from locking hole and move handle to unhitching position by pulling out and rotating toward the cab. 5. Drive truck slowly away from trailer. Note: If there is tension between truck and trailer, the handle may start to return to ready-to-receive position, but the trailer will still uncouple.
The bail pin lock hole accepts a pin with diameter of 5/16" or less. The lock opening dimensions are 1-1/2" or greater in length and 3/4" or greater in height.
Yes, the center section can be rotated 180 degrees to increase the gap between the trailer front and truck cab by 1-1/2". This requires removing the head unit, removing the bolts holding the legs to the center section, rotating the center section, and reconnecting. The location of the kingpin should remain ahead of the truck rear axle with proper truck cab clearance. Note: This rotation is not possible with RAM vehicles; instead, disconnect the feet from the bed, rotate the center section and leg assembly, and reconnect per leg installation instructions.
When rotating the center section for added cab clearance, remove the head springs by removing the 1/4" bolt (7/16" socket) and flip them from right to left. When installed properly, the springs should point up toward the truck cab and be tightened to 7-8 ft-lbs. The springs will flex freely when properly installed.
During hitching: Ensure blocks/chocks are firmly against trailer wheels, landing gears are on the ground supporting trailer weight, and the trailer brake is on. Make sure no one is between the truck and trailer during the pull test. During unhitching: Ensure no person or vehicle is in the vicinity of the truck or trailer, as they may shift when the handle is pulled. Blocks must be firmly against trailer wheels and landing gears must be lowered and firmly on the ground.
Pinch points exist at the head unit when installing and removing it from the center section. Avoid putting any body parts in pinch points when placing the head unit on the center section. When removing the head by pulling spring clips, a slight push down on the head will help, but avoid getting fingers pinched. When rotating the center section for added cab clearance, pinch points exist at the head springs and pivot interface; place hands or fingers on either side of the pivot interface to prevent pinching.
The M5 Head & Center Section is designed for use with M5 mounting legs (sold separately). Compatibility depends on your truck model and the M5 leg assembly you select. Refer to the leg installation instructions for specific vehicle fitment information.
You need fastener kit 30892F, M13 and M24 sockets and wrenches, a torque wrench, and a grease needle. Additional fasteners are supplied with the M5 mounting legs (sold separately).
The manual does not specify drilling requirements for the head and center section installation. Drilling requirements depend on the M5 mounting legs used; refer to the leg installation instructions.
Head spring bolts (1/4" bolts) should be tightened to 7-8 ft-lbs when the center section is rotated for added cab clearance.
Apply grease to the skid plate and trailer kingpin every use. Apply grease via the grease fitting on top of the unit and to internal mechanisms annually or as required using a grease needle and spray white lithium grease.
The hitch is rated for 32,000 lbs towing capacity with a maximum pin weight of 6,400 lbs. You must not exceed your vehicle manufacturer's recommended towing capacity.
The bottom of the pin box should be aligned with the top of the skid plate ramp ±1 inch for proper hitching. Refer to the leg installation instructions for height adjustment details.
If the jaw does not close when fully backed into the trailer, pull the truck slowly forward to remove load on the jaw. The handle will then fully latch. This occurs because the jaw may not close if under compression.
The pivot assembly resistance is preset at the factory. If the head pivots and makes noise when the trailer is not attached, tighten the pivot bolt 1/2 turn at a time, with a maximum of 2 full turns. Access the pivot bolt and nut through the logo/load rating slot using an open-end wrench (see figure 9B).
If the trailer separates from the hitch during the pull test and the truck moves forward, the trailer is not properly hitched. Repeat the hitching procedure (steps 1-3): reposition the truck and trailer, ensure the head is in Ready-to-Receive position, and back the truck slowly into the trailer so the kingpin and 5th wheel funnel align. The hitch should latch automatically when fully backed in, and the indicator should show 100% green.
