The CURT weight distribution hitch is a specialized towing system that provides improved vehicle and trailer control by leveling the trailer and more evenly distributing its tongue weight across the trailer's and vehicle's axles. Weight distribution hitches are commonly used on travel trailers and campers but can also be applied to other large loads. CURT WD hitches come with a 2" x 2" shank and are compatible with class 3, 4 and most 5 trailer hitches, including Xtra Duty and Commercial Duty (2-1/2" replacement WD shank may be required), as well as some RV trailer hitches. While a weight distribution hitch will increase the gross trailer weight capacity of most trailer hitches, the vehicle's weight carrying capacity must be taken into consideration before towing a heavier trailer (NOTE: Never exceed the lowest weight capacity of any towing component).This trunnion bar weight distribution hitch features a heavy-duty formed head and square spring bars constructed from forged steel. It offers a gross trailer weight capacity up to 10,000 lbs. and a tongue weight capacity of 1,000 lbs. It also includes hook-up brackets, spring bar safety chains and a pin and clip. To protect this hitch from scratching, chipping, rust and UV damage, it also comes with a durable black powder coat finish. A trailer ball must be purchased separately.

The CURT 17302 is a weight distributing hitch designed to distribute trailer tongue weight across the towing vehicle's axles, improving stability and handling when towing. It uses spring bars and lift brackets to level the vehicle when a trailer is coupled. The 17302 model is rated for a gross trailer weight not to exceed 10,000 lbs. and a tongue weight not to exceed 1,000 lbs. when used without spring bars. With spring bars installed, it handles 8,000–10,000 lbs. gross trailer weight and 800–1,000 lbs. tongue weight.
The CURT 17302 is designed for trailers with A-frame tongues and a 1 1/4" threaded-shank hitch ball coupler. If your trailer has a straight (pole) tongue instead, you will need to order a pole tongue adapter separately. The hitch is rated for trailers with a gross weight of 8,000–10,000 lbs. and tongue weight of 800–1,000 lbs. when spring bars are used. Check your trailer's specifications against these ratings and confirm your coupler type before purchasing.
No, the CURT 17302 is designed for a 1 1/4" threaded-shank hitch ball. If you require a 1" shank, you must order a CURT reducer bushing #21101 separately and use it with the hitch head assembly.
Yes, but you must deflate air springs and air shocks to their minimum recommended pressure before assembling and adjusting the weight distributing hitch. Consult your vehicle's owner's manual or the air suspension manufacturer's instructions for the correct minimum pressure. This step is essential for proper hitch setup and weight distribution.
You will need a wrench and a torque wrench. The manual specifies torque values of 200 ft. lbs. for the 3/4" bolts, 75 ft. lbs. for the 1/2" head attachment bolts, and 50 ft. lbs. for the set-screw. A tape measure is also needed to measure coupler height, vehicle bumper heights, and ball height during setup. A trailer tongue jack is required to level the trailer and raise it during installation.
The kit includes: hitch head, adjustable shank bar, 2 spring trunnion bars, 2 snap-up brackets, pipe handle, 2 lift chains (8mm x 400mm), 1 bolt (5/8" - 11 x 1 1/2"), 2 hex bolts (3/4" - 10 x 5"), 4 conical washers (3/4"), 2 nylock nuts (3/4" - 10), 1 hitch pin (5/8" x 3"), 1 clip, 2 U-bolts (3/8" - 16), 4 nylock nuts (3/8" - 16), 2 bolts (1/2" - 13 x 2"), 2 bolts (1/2" - 13 x 4"), 2 clips for snap-up brackets, 1 short adjustment rod, 1 long adjustment rod, and 2 flat washers (1/2"). You must supply the hitch ball separately.
The uncoupled ball height is determined by measuring your trailer's coupler socket height from the pavement, then adding an allowance for vehicle squat when the trailer is coupled. For passenger cars, add 1/8" for each 100 lbs. of tongue weight to the coupler height. For example, if your coupler is 18" high and your tongue weight is 800 lbs., add 1" (8 × 1/8"), making your target uncoupled ball height 19". The hitch head is then positioned on the shank at the nearest bolt hole that matches this target height. This ensures the ball will be at the correct height once the trailer is coupled and the vehicle settles.
The adjustable shank bar can be inverted to obtain proper ball height on high ground clearance vehicles, as shown in Figure 3 of the manual. However, if you invert the shank, you must check for adequate ground clearance to ensure the inverted shank does not contact the pavement or other obstacles during normal driving and turning.
Attach each lift chain (8mm x 400mm) to the tapered end of each spring bar using a 3/8" U-bolt and 3/8" nylock nut. Position the U-bolt so that 2 to 3 threads extend through the bottom of the locknut. The chain must be free to move within the U-bolt. Before installation, apply heavy fibrous grease to the top section of each spring bar.
Hold each spring bar perpendicular to the shank with the trunnion ribbed side facing up. Insert the bottom knob of the trunnion into the lower pocket of the head assembly. Then rotate the spring bar upward so the top knob of the trunnion passes through the entrance slot in the upper pocket of the head assembly. Apply heavy fibrous grease to the top section of each spring bar before installation.
After raising the front of the trailer and back of the tow vehicle approximately 3" with the tongue jack, position the lift bracket on the trailer tongue so that the lift chain is centered between the bracket. The chain must be vertical and not angled fore or aft, or it may catch on the bracket when turning and cause damage. If your trailer has an obstruction on one side of the frame, order an offset lift bracket kit from your dealer and follow its installation instructions.
Install the 1/2" - 13 bolt (either #15 or #16, depending on frame width) into the threaded hole in the lift bracket. Turn the bolt in until it contacts the trailer tongue, then tighten an additional 1/4 turn with a wrench. Do not overtighten. This bolt is not meant to be fully torqued; it is a light attachment to hold the bracket in position.
Install the 3/4" - 10 x 5" hex bolts through the conical washers and through the head channel holes. Rotate the head forward as far as it will go; the ball should be vertical or tilted slightly back. If the ball is not in the correct position, remove the short adjustment rod and replace it with the long adjustment rod, or change the number of washers on the rod and reassemble. You can also adjust head tilt by changing the number of chain links between the lift bracket and spring bar.
1. Slip the marked chain link over the hook on the lift bracket. 2. Insert the lift handle onto the heavier rod above the chain attachment. 3. Using the handle, raise the lift bracket up and over center so it is fully seated against the mounting bracket. 4. Secure by inserting the clip through the lift bracket and mounting bracket. Ensure the chain is not twisted and the hook extends through the link. Before raising, raise the front of the trailer to reduce chain tension and make operation easier and safer.
1. Remove the locking pin from the lift bracket. 2. Insert the lift handle onto the rod above the chain attachment. 3. Carefully lower the bracket with the handle. It will require effort to bring the bracket over center and then to resist the chain tension as the bracket rotates downward. Before lowering, raise the front of the trailer to reduce chain tension and make operation easier and safer.
There must be at least 5 links between the lift bracket and the spring bar to allow movement when turning. If fewer than 5 links are used, the chain and snap-up bracket will bind. The number of links should be the same on both spring bars. After installation, mark the spring bar chain at the hooked position with paint for future reference. If your trailer has surge brakes, you may need to increase the number of chain links to allow the brake actuator to function correctly.
Tighten the 3/4" - 10 x 5" hex bolts and their corresponding 3/4" - 10 nylock nuts to 200 ft. lbs. torque. Failure to tighten these bolts to the correct specification may result in fastener loss or failure. The top bolt should be tightened just enough to hold the head tight against the pin in the head channel before final tightening.
Tighten the 1/2" - 13 head attachment bolts to 75 ft. lbs. torque. Failure to tighten these bolts to the correct specification may result in fastener loss or failure.
Tighten the set-screw to 50 ft. lbs. torque. Failure to tighten the set-screw to the correct specification may result in fastener loss or failure.
The loaded ball height (when the trailer is coupled) must never be greater than the uncoupled ball height. If the loaded ball height is higher than the uncoupled height, it causes front wheel overload and loss of rear wheel traction, leading to unstable handling, reduced braking ability, and a tendency to jackknife when turning or braking. If you observe this condition, reduce the take-up on the spring bar chains, re-measure, and adjust until the proper height is obtained.
Before towing, check the following: pin and clip securing shank to receiver; head to shank fasteners; trailer ball nut; coupler latch; snap-up bracket bolt; safety chains; lights and turn signals; and braking system, including breakaway switch. At the beginning of every tow day, check all trailer to towing vehicle connections for security and operation.
Tongue weight should be 10–15% of the gross trailer weight for most trailers. Too low a tongue weight often produces a tendency to sway. Ensure your trailer's tongue weight does not exceed the CURT 17302 rating of 1,000 lbs. (or 800–1,000 lbs. when spring bars are used). Consult your trailer manufacturer's specifications and your towing vehicle's owner's manual for specific recommendations.
A sway control device is recommended, as it can help minimize the effects of sudden maneuvers, wind gusts, and buffeting caused by passing vehicles. Use of a sway control device is especially recommended for trailers with a large surface area, such as travel trailers. The CURT 17302 head assembly will accept two sway control attachment balls.
No. Trailers should not be occupied while being towed. Most states enforce this regulation. Always ensure all passengers remain in the towing vehicle during towing.
Always hook up all of the trailer lights, electric brakes, and break-away switch connections whenever the trailer is being towed. Failure to make these connections is unsafe and may violate state regulations.
If any part of your towing system bottoms out or if you suspect damage may have occurred in any way, pull over and make a thorough inspection. Correct any problems before resuming travel. Severe bumps and badly undulating roads can damage your towing vehicle, hitch, and trailer, and should be negotiated at a slow, steady speed.
Keep the socket-mounted ends of the spring bars and the lock pins in the head assembly free from dirt and well lubricated. Excessive wear in this area may indicate an overload or inadequate lubrication. Keep the head assembly exterior clean and do not allow dirt or stones to lodge between the spring bars and the head. Keep lift brackets clean and lubricated to ensure ease of operation. Keep hitch parts painted to prevent rust and maintain good appearance, but do not paint over labels. Coat the clevis pins in the head assembly with fibrous grease. Clean the ball and coupler socket and coat the ball lightly with grease.
Check spring bar chains and U-bolts for wear and security regularly. Replace them if they become worn. The manual does not specify a particular interval, but recommends checking them at the beginning of every tow day and periodically throughout the towing season.
Yes. Remove the weight distribution hitch from the trailer hitch on the towing vehicle when not towing a trailer. This reduces the chances of striking the weight distribution hitch on the driveway or other objects and reduces the chance of parts being stolen. Some states also require a clear view of license plates; if the trailer ball restricts the view, remove it when not in use.
After adjusting the spring bars, re-measure the front and rear bumper reference points that you marked before installation. The vehicle should settle evenly, within 1/2". If the front has settled much more than the rear, increase the number of chain links between the lift bracket and the spring bar. The spring bars should be nearly horizontal when correct height is achieved. Once even settling and correct spring bar position have been achieved, mark the spring bar chain at the hooked position with paint for future hook-up reference.
Yes, if your vehicle has air springs, air shocks, or automatic leveling systems, deflate them to their minimum recommended pressure before assembly. Consult your vehicle's owner's manual for the correct minimum pressure.
Tighten 3/4" bolts to 200 ft. lbs., 1/2" head attachment bolts to 75 ft. lbs., and the set-screw to 50 ft. lbs. Failure to tighten correctly may result in fastener loss or failure.
The maximum tongue weight is 1,000 lbs. without spring bars and 800–1,000 lbs. with spring bars. Never exceed your vehicle manufacturer's recommended towing capacity.
Check the hitch pin and clip, head fasteners, trailer ball nut, coupler latch, snap-up bracket bolt, safety chains, lights and turn signals, and braking system including the breakaway switch.
Keep spring bars and lock pins lubricated and free from dirt. Keep lift brackets clean and lubricated. Coat the ball lightly with grease. Check spring bar chains and U-bolts for wear regularly. Keep hitch parts painted to prevent rust, but do not paint over labels.
This condition causes front wheel overload, loss of rear wheel traction, unstable handling, reduced braking ability, and a tendency to jackknife. Reduce the take-up on the spring bar chains, re-measure the ball height, and adjust until the proper height is obtained. The loaded ball height must never exceed the uncoupled ball height.
If the lift chain is angled fore or aft at the top within the lift bracket, it may catch on the bracket when the trailer turns, which could damage the lift bracket or pry it open. Reposition the lift bracket on the trailer tongue so that the chain is centered between the bracket and runs vertically. If your trailer has an obstruction on one side of the frame, order an offset lift bracket kit from your dealer.
If the front has settled much more than the rear (more than 1/2" difference), increase the number of chain links between the lift bracket and the spring bar. The spring bars should be nearly horizontal when correct height is achieved. Ensure the number of links is the same on both spring bars.
There are fewer than 5 links between the lift bracket and the spring bar. The minimum of 5 links is required to allow movement when turning. Increase the number of chain links to at least 5 on both spring bars.
Surge brakes require a small amount of fore and aft movement for their actuating mechanism to function correctly. To avoid restricting movement, increase the number of chain links between the lift brackets and spring bars by tilting the head down. Some surge brake actuators not designed for use with a weight distributing hitch may bind. Check your surge brake operating instructions for specific requirements regarding their use with weight distributing hitches.
