Twin-Cam 88® Valve Springs and Kits by Crane

Crane valve springs are manufactured from the finest quality spring wire and precision wound. The highest quality and reliability is assured with rigid quality control procedure. 

We also offer the Thermo Cool spring. Thermo Cool coating reduces the friction between coils and rapidly disperses heat, it runs cool and allows your valve train to operate smoothly and efficiently.

The chromemoly 4140 steel retainers are the strongest and most durable steel retainers offered. They also eliminate inaccurate assembly heights and retainers that pull through with lesser quality steel retainers. 

Our titanium retainers reduce weight and add strength to a performance valvetrain assembly. The reduced weight of a titanium retainer allows the valve to move more easily and will require less spring pressure to operate. This makes your motor rev quicker and will produce more power.
