Performance Shock Valving Guide

How Shocks and Shock Valving Works Shock absorbers dampen the suspension movement of a vehicle to improve handling and performance by forcing specially formulated shock oil through tightly controlled holes (ports) in the shock piston to convert kinetic energy (movement) into thermal energy (heat). Most high performance shocks are similar in design and feature a […]
