Description

QA1 offers a complete line of shock and strut components to maintain or upgrade your auto suspension. These include piston rods, bushing sleeves, nitrogen gas bags, hardware, and more.

Product Overview

These pistons have flat linear compression and digressive rebound with up to 0.056" of preload to generate low-speed control without excessive high-speed forace, helping you maintain grip over surface irregularities. Used on both dirt and asphalt cars, these pistons can generate the force numbers you're looking for to keep the left rear up or keep the front end sealed off.
