Overview

Designed for a clean installation, the RAM-B-231Z-2U base accommodates most common rail and bar sizes on Side By Sides and ATVs. With the strap clamp safely concealed 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, allowing you to modify the mount for another mounting location. The base also includes black cover caps to be placed over the exposed ends of the U-bolt.

QUESTIONS & ANSWERS

Have a Question?

Ask a Question
  • I have to mount to a 4 inch tube. What are my options? Will this product work?

    This will be able to mount to a 4" tube. The strap has a clamp range of 1.57" - 3.15". To make this product fit on a 4" tube, you will need to source a larger hose clamp from a local hardware store. Our mount can connect to any size rail if additional third party hose clamps of any size are sourced and used with the mount.

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.
