Features to know about

Keeps Trailers Level and Stable: 3-3/4" Drop or 3-1/2" Rise

When you’re hauling with different trailers, keeping things level is key for smooth, safe towing. This adjustable mount gives you a maximum 3-3/4" drop or 3-1/2" rise so you can dial in the perfect height match. The channel design adjusts in 1" increments, giving you precise control to line up your trailer without guesswork.

Tows Heavy Loads with Confidence: Up to 10,000 lbs GTW

Built for serious hauling, this steel mount handles up to 8,000 lbs with the 2" ball and 10,000 lbs with the 2-5/16" ball. The heavy-duty construction gives you peace of mind when towing large campers, boats, or equipment trailers. With tongue weight ratings of 800 lbs and 1,000 lbs depending on ball size, it’s a dependable setup that stands up to demanding loads.

Reduces Rattle and Vibration: Anti-Rattle Shank Design

No one likes noisy gear clanking down the road. The anti-rattle design helps cut down on movement inside the receiver so your tow feels smoother and quieter. It keeps everything snug and stable without added play in the hitch.

Adjusts Fast for Different Trailers: Dual-Ball Platform

Switching between trailers with different couplers is simple here. The dual-ball setup includes both a 2" and 2-5/16" ball that can be rotated by removing the pins and flipping the platform. You can change height or ball size quickly without tools, making it practical for folks who tow more than one type of trailer.

Built to Last: Durable Powder Coat and Zinc-Plated Balls

Road grime and weather can eat through lesser finishes fast. This mount’s black powder-coated steel shank and zinc-coated balls stand up to corrosion from rain, salt, and dirt. It stays looking good and working right over time, even when it lives on your truck full-time.

Excellent quality



by:

Great product, it is exactly as described, fit and finish is nice, making adjustments is simple. I have had several people ask me where to get this insert because of how well it works and what it costs. No complaints here.



by:

Thought it was made in America. Still seems a solid hitch.



by:

Good quality and fits nicely.



by:

Long time customer all etrailer products are first class!!



by:

Just wish the actual hitch box was in a shipping box.



by:

Shipping was fast,the Curt adjustable mount is sturdy and everything worked easily,fits my Chevy Colorado Zr2 perfectly



by:

Terrri was great. She was able to hunt down the very specific items I needed for my business and did it while being pleasant and professional. I was looking for these items for a few days before I contacted etrailer. I had my item in time for the event I needed it for and I wouldn't go anywhere else if the need for anything to do with my trailer arises again. Thank you Terri, great job!!



by:

The hitch arrived on time and was packed well. The hitch itself is well built and appears very sturdy. It will fit easily under my rear seat and was easy to install and change the height to level my trailer.
Curt makes great products, and this no no different



by:

It is exactly as described. It weighs about 15 pounds which makes it a little easier to handle and is easily adjusted from one setting to another. It also extends a little further from my vehicle and allows for more clearance between my rear bumper and the hitch. It is a good adjustable mount for the money.



by:

Hitch works great for my Pathfinder. I needed just a little extra lift to get the boat trailer level and keep the front nose down a bit. We take a 16 foot deep v aluminum boat fishing and loaded to brim on vacation. This hitch did what I needed it to do. Plus with 2 5/16 ball if I have move some trailer around I can use this versus getting the big truck around to just swing empty trailers around.



by:

Ric from customer service was awesome to work with. My order came a day early and was packaged that prevented any damage to the 4 individual products that I purchased. Best customer service, ordering process and product quality. Highly recommend etrailer!!!



by:

Fits securely and smoothly, am excited to finally have a sturdy hitch that is adjustable for many farm trailers, implements, etc.
