SKU: 612314459179 Category:


If you own multiple trailers or frequently tow a variety of loads, you know how much time and money are spent tailoring your towing system to each and every individual trailer. There is nothing more inconvenient than switching back and forth between a few different ball mounts and trying to remember which mount fits with which trailer. A CURT adjustable ball mount is your multipurpose towing solution. Its key feature is its adjustable design that takes the form of an adjustable channel-style assembly. It uses a series of holes to allow the ball mount platform to be vertically adjusted and allow for significant flexibility in drop and rise. With a variable ball height, it can easily accommodate different coupler heights and multiple trailers.

This adjustable channel-style replacement shank features a solid 2 1/2″ shank, multiple mounting holes and can accept a variety of channel-mount attachments. It features nine holes with a total height of 9 3/4″, and it fits part #45902 (NOTE: Always abide by the lowest rated towing component). It can accept pins and clips #45915 or a lock set #23556, and it also has two holes in the shank for an 11″ or 12″ length.

For long-lasting rust, scratch and UV resistance, this adjustable shank also comes with our durable carbide black powder coat finish to give you peace of mind for the road ahead.
