Overview

Designed for a clean installation, RAM-231Z-2U base accommodates most common tubing sizes on Side By Side’s and ATV's, allowing for the placement of the RAM rubber ball base. Safely concealing a strap clamp in a compact housing, you won't have to worry about exposed sharp edges or unwanted loosening. Included in the kit is a zinc coated metal u-bolt, this allowing you to modify the mount to accommodate mounting location. The base also includes black cover caps to be placed over the exposed ends of the u-bolt.

Reading part numbers

The letter after RAM tells you the ball size: RAM-B-166 uses a 1" B ball, while RAM-D-201 uses a 2.25" D ball. C size parts are the exception and carry no letter, so RAM-201U is a C size arm.
