Description

Dual Valve Springs from COMP Cams are manufactured from Super Clean wire and subject to extensive quality control testing to deliver a valve spring assembly with superior strength, durability and valve train stability, no matter what the application. The dual spring design creates a stronger valve spring that can easily handle the increased lift found in extreme stress applications. COMP Cams Dual Valve Springs exceed the expectations of today's engine builders and racers.

Product Overview

COMP Cams Elite Drag Race Dual Valve Springs are unlike any existing springs on the market. They feature a new proprietary, cutting-edge, progressive pitch coiling process from COMP that greatly improves durability and ensures safe spring life beyond traditional extreme-duty expectations. The COMP Cams Elite Drag Race Dual Valve Springs are smaller in diameter and feature higher frequencies. These new dual valve springs are coiled with a revolutionarily new process that enhances durability by engineering the outer spring precision to the interface with the inner spring. The Elite Drag Race Dual Valve Springs use a smaller, lighter retainer engineered with a newly developed and specially formulated spring steel. This exclusive design and use of lighter retainers substantially increases the longevity in extreme conditions, such as professional drag racing. Exclusive clean wire sourcing and precision micro-finishing are standard on every COMP Cams Drag Race Dual Valve Spring. Each individual spring is hand selected and matched with proper tolerance fitment between inner and outer springs.
