Description

The XDP Performance Valve Springs & Retainer Kit XD386 are a perfect upgrade for your modified 2001-2016 GM 6.6L Duramax. Camshaft upgrades and other modifications that increase boost require more valve control. The XDP Performance Valve Spring feature a conical design for better valve control than a standard straight spring. The conical design also allows for smaller and lighter spring retainers. Each spring undergoes a stress relief process and is computer load mapped, to ensure quality and long-term reliability. Each spring is matched within 1 lb of seat pressure to ensure consistency. Sold as a complete set with valve springs, retainers, and locks. Each kit is backed by XDP's 2-year unlimited mileage warranty.
