Description

This kit features ASTM A877A OTSC round wire steel springs, 6AL4V American titanium retainers, and 4140 heat-treated chrome molly steel spring seats. It offers a 20% stiffness increase and a 71% weight reduction in retainers over OEM components.

The kit includes one valve spring, one retainer, and one spring seat per cylinder. It is engineered to support higher revving applications and prevent issues like misfires above 5,000 RPM.
