QA1 9057-312 35MM Piston for Large Body Circle Track Shock

The QA1 Precision Products 9057-312 is a 35mm replacement piston designed specifically for large body circle track shocks. This precision-engineered component features a 1.0 to 1.5 degree linear-digressive valving configuration, providing progressive damping characteristics that improve handling and control on oval track surfaces.

Key Features:

• 35mm piston diameter for large body shock applications
• 1.0 to 1.5 degree linear-digressive valve design
• Engineered for circle track racing applications
• Precision-manufactured to QA1's exacting specifications
• Allows fine-tuning of shock damping characteristics

This piston enables racers and suspension tuners to customize shock performance for specific track conditions and vehicle setups. The linear-digressive valving provides smooth transitions between compression and rebound cycles, helping maintain tire contact and chassis stability through corners.
