Product Overview

This is a 2.5in diameter aluminum-body monotube shock with a true internal floating piston (IFP) that separates gas and oil for fade-resistant damping. Race-developed main piston valving is tuned specifically for the Silverado 2500HD chassis.

Aluminum construction dissipates heat four times better than steel, keeping damping consistent on long trails and washboard roads. Fully serviceable and corrosion-resistant for a lifetime of rebuilds.
