PISTON ROD 15MM OD BLEED ADJ. 7IN

The PISTON ROD 15MM OD BLEED ADJ. 7IN is a precision-engineered suspension component designed for high-performance shock absorber systems. This adjustable piston rod serves as a critical internal component in dampers, allowing fine-tuning of fluid flow rates through the shock's valving system. Built for automotive enthusiasts and professional technicians who demand reliability and consistent performance across varying driving conditions, this component is essential for maintaining optimal suspension dynamics and ride quality.

Manufactured by QA1, a leader in suspension technology, this 7-inch piston rod features a 15mm outer diameter and bleed adjustment capability for precise dampening control. The bleed adjustment mechanism allows users to regulate the rate at which shock fluid bypasses the main piston valve, directly influencing rebound and compression characteristics. This level of adjustability is critical in performance applications where suspension tuning must adapt to track conditions, load variations, or driver preference. The rod's construction ensures smooth operation over extended service intervals while maintaining the structural integrity required for both street and competition use.

This piston rod is ideal for customers building or restoring custom coilover kits, upgrading factory shock assemblies, or maintaining high-end performance dampers. Installation typically requires basic mechanical knowledge and proper shock service tools. Compatibility depends on your shock absorber body diameter and desired stroke length, so verify that your existing shock assembly accepts 15mm rods with 7-inch stroke specifications. QA1 components are trusted by drag racing teams, road course competitors, and street performance builders who require repeatable, adjustable suspension performance.
