Pistons - Twin Tube

QA1 Twin Tube Pistons

Tailor your twin tube shock curves with these pistons from QA1.

Large Body Linear Piston: Creates a force curve that features an increase in force directly related to an increase in speed - the quicker the shock moves, the stiffer it becomes.

Small Body Linear Piston: Same characteristics as the large body linear piston, but for smaller diameter shocks. 0.02" bleed.

Variable Linear/Digressive Piston: Features 0.056" of preload to help generate low-speed control without excessive high-speed force. The amount of shim stack preload, bleed, shim thickness and diameter are all options builders can use to tailor the rebound curve at different speeds.

Two-Port Piston: Allows the valve discs to open consistently which results in a smoother force curve and accommodates independent compression and rebound circuits for precision in low-speed force control.
