The CURT QuickPin trailer coupler is a revolutionary coupler design, doing away with the traditional latch mechanism for simple, stress-free trailer hookup. Most couplers use a complicated hinging latch that's prone to wear out and become corroded, leading to difficulties and frustration. Instead of a latch, QuickPin uses a simple hitch pin to create a safe, reliable, hassle-free towing connection. It's as easy as dropping the trailer tongue onto the hitch ball, inserting the QuickPin hitch pin, and that's it! No more wrestling with a rusty latch, and no adjustment or tightening needed. This trailer hitch coupler is fully tested according to SAE J684 specifications. It is rated for 3,500 pounds and fits any standard 2-inch diameter trailer ball. The coupler channel can be mounted on a 2-1/2-inch wide trailer tongue beam, featuring standard mounting holes to fit most existing bolt patterns (mounting hardware not included). It is also finished in a durable black powder coating for lasting rust resistance. NOTE: This coupler comes with a 1/2-inch pin that must be used when connecting the trailer. It may not be replaced with a different 1/2-inch pin.

Call 888-634-9494The CURT 25471 has a gross trailer weight (GTW) capacity of 3,500 lbs. and a tongue weight (TW) capacity of 350 lbs. Never exceed your vehicle manufacturer's recommended towing capacity.
The CURT 25471 is designed for trailers with a 2-1/2" channel tongue. CURT also offers the 25470 for 2" channel tongues and the 25472 for 3" channel tongues. Verify your trailer's tongue channel size before purchasing.
The coupler itself is included. The 1/2" grade 5 bolts and nylock nuts required for installation are not included and must be purchased separately. You will need 4 bolts and 4 nylock nuts.
You will need a ratchet, torque wrench, socket set, socket extension, and box end wrench set. For a full tools reference guide, visit curtmfg.com/trailer-hitch-installation.
The installation is rated as "Easy" based on time and effort involved. However, difficulty may vary depending on installer expertise, vehicle condition, and proper tools and equipment. Ensure you have all required tools before beginning.
Bolt the coupler to the front of the trailer tongue using 1/2" grade 5 bolts and nylock nuts. Use all available side mounting holes. Note: the pin guide hole is not a mounting hole. Torque all hardware to 55 ft.-lbs. Read all instructions thoroughly before beginning.
All 1/2" bolts must be torqued to 55 ft.-lbs. Use a torque wrench to ensure proper tightening and prevent damage to the product or vehicle.
Remove the pin & clip from the pin guide hole. Lower the coupler over the trailer ball until the ball is fully seated in the ball pocket. Insert the provided pin through the pin guide hole and fasten the clip through the end of the pin. If the pin does not pass through the coupler completely when the ball is fully seated, DO NOT TOW.
Block the trailer's wheels. Remove the pin & clip from the pin guide hole and raise the trailer off the trailer ball. Place the pin & clip back into the pin guide hole.
No. Only use the pin & clip provided with the coupler. Using an alternate pin & clip could result in property damage, serious bodily injury, and/or death.
Periodic inspection of your coupler should be performed to ensure all hardware and components remain secure. Check that bolts remain tight and that the coupler is rigidly attached to the trailer tongue.
The coupler has a gross trailer weight capacity of 3,500 lbs. and tongue weight capacity of 350 lbs. However, you must never exceed your vehicle manufacturer's recommended towing capacity, which may be lower than the coupler's rating.
The 25471 fits 2-1/2" channel tongues. The 25470 fits 2" channel and the 25472 fits 3" channel.
No. You must purchase 4 x 1/2" grade 5 bolts and 4 x 1/2" grade 5 nylock nuts separately.
No drilling is mentioned in the manual. The coupler bolts to the front of the trailer tongue using all available side mounting holes.
Torque all 1/2" bolts to 55 ft.-lbs. using a torque wrench.
The tongue weight capacity is 350 lbs. with a gross trailer weight capacity of 3,500 lbs.
DO NOT TOW. If the pin does not pass through the coupler completely when the ball is fully seated, there is a problem with the coupling that must be resolved before towing.
