Product Overview

This is a 2.5in aluminum-body monotube rear shock with a race-developed main piston and a true internal floating piston (IFP) that separates gas and oil for fade-resistant performance.

Application-specific valving extends drop-out travel off-road while reducing body sway on the street. The aluminum body dissipates heat four times better than steel, and the shock is fully serviceable.
