Features to know about

Keeps Every Trailer Level: Adjustable Drop up to 9-1/2"

Different trailers rarely line up at the same height. This adjustable aluminum mount makes it easy to level out each one. Slide the dual-ball platform along the shank and lock it in place with the included pins and clips to fine-tune your setup in 1" increments. With a maximum drop of 9-1/2", it helps you keep everything level and steady on the road.

Handles Heavy Loads with Confidence: 10,000 lbs GTW Rating

When you’re pulling serious weight, strength matters. This mount tows up to 8,000 lbs with the 2" ball or 10,000 lbs with the 2-5/16" ball, and tongue weights of 800 lbs and 1,000 lbs respectively. The solid aluminum shank keeps things rigid without adding unnecessary bulk, giving you dependable performance for long hauls or weekend towing.

Simplifies Trailer Swaps: Dual Polished-Steel Hitch Balls

Switching between trailers doesn’t have to mean swapping hitches. The dual-ball platform gives you both a 2" and a 2-5/16" polished-steel ball in one setup. Just pull the pins, rotate to the ball size you need, and reinsert—no tools required. It’s a quick way to move between different coupler sizes without slowing down your day.

Fights Corrosion While Cutting Weight: Lightweight Aluminum Build

A combination of strength and corrosion resistance keeps this mount looking good and working right. The billet-aluminum construction is tough yet light, making it easier to handle while resisting rust from salt or road grime. It’s built for everyday towing without the extra maintenance that comes with steel setups.

Stays Quiet and Secure: Vibration-Resistant Hardware

No one likes rattle or slop when towing. The included vibration-resistant clips hold the adjustment pins tight so everything stays solid on the move. Once set, the platform stays put from driveway to destination, keeping your hitch quiet and your trailer steady every mile.

Video Transcript for Let’s Check Out the Curt Alumalite Aluminum Adjustable 2-Ball Mount

Hello everybody, this is Jeff at etrailer.com. Today, we're gonna take a look at this CURT AlumaLite aluminum adjustable two ball mount with the 9-1/2 half inch drop for a two inch hitch, has a 10,000 pound maximum gross towing weight capacity. Now, this is a lightweight build aluminum ball mount. If you notice, has this dual ball platform that'll let you hook up your trailer to your tow vehicle. The shank portion right here is what'll slide into your two inch hitch receiver and it is secured with included 5/8 inch diameter steel pin and clip. The ball up front is what'll provide the connection point for your trailer coupler.

And if you notice, it has a dual ball mount, so it has two different sized polished steel hitch balls so it'll let you tow trailers with different coupler sizes. Basically, you have either the choice of a 2-5/16 diameter ball, or if you flip it over a two inch diameter ball. And to switch the ball, it's pretty easy. You just simply move the pin and the clip right here, take it out, put the ball in what size you need and then put it at what height you need. What's nice is that adjustable height on this will let you tow trailers of different heights with the same vehicle.

This will provide a maximum drop of 9-1/2 inches, which is if you put it in the very furthest hole down here, and it is easily adjustable in increments of one inch. That's the distance between each hole here. Now, this is to be used in the drop position only. It's not to be used in the rise position. So basically what you'll do is just slide the ball platform up or down the shank and then secure it in place with the included pin and vibration resistant clip.

And just to show you the clips and the pins are very nice 'cause they have that nice neural knob on one end, clip on the other end, very high quality steel pin. You just slide them through and then clip it right into place just like that. Same on this one. Now, the pins are two different lengths, so you use the longer pin down here and the shorter pin up here. This is a lightweight build aluminum construction, so it is corrosion resistant.

The pins we mentioned are steel. Now, if you do wanna secure it more, you can use the hitch lock. We do sell hitch locks separately on our website. There is two that CURT makes especially for this. There's a part number C23556, which will include a pin, a lock for here and here. Or you can get a part number C23025, which would just be a pin for your hitch itself. A few specs on this, if it's two inch by two inch trailer hitch receivers, to go over some specs on this, the gross towing weight and tongue weight capacity will depend on the ball size you use. So if you use the larger 2-5/16 diameter ball, it'll get you a 10,000 pound gross towing weight capacity, which will be stamped on the top of the ball and a tongue weight of 1,000 pounds. If you flip it over and use the smaller two inch ball, it'll be stamped with 8,000 pound gross weight capacity and an 800 pound tongue weight capacity. Last thing is the distance. There's two hitch pin holes, one's further away, one's closer. The distance of these hitch pin holes from the center of it to the center of the ball, on the closest one is gonna be 7-3/4 inches. The furthest one away is 9 inches center to center. But that's gonna do it for the review on this CURT AlumaLite aluminum adjustable two ball mount with the 9-1/2 inch drop for a two inch hitch.

Very nicely CNC machined drop hitch with the perfect amount of drop that I needed (7")
Note it says on the box that it cannot be used to raise the hitch, only to drop.

Awesome hitch. Glad I made the purchase!
