Product Overview

This OEM Performance Series rear shock pair pairs a 2.5in diameter monotube body with a piggyback remote reservoir to keep oil cool under sustained load.

The integrated adjuster lets you dial in compression damping for towing, hauling, or fast desert work without re-valving.

Each kit is custom-tuned and real-world tested on the GMT900 HD platform to find the optimal damping curve for this truck.
