- Ultra-durable stainless steel construction withstands heavy valve spring loads.
- High-lift 1.8 ratio multiplies lift to optimize intake and exhaust flow.
- Heavy-duty roller tip minimizes friction and reduces valve stem side-loading.
- Designed for secure installation on standard 3/8-inch mounting studs.
- Tailored for high-performance gm ls1, ls2, and ls6 powertrains.
Combining the extreme tensile strength of stainless steel with a high-lift 1.8 ratio, this roller rocker set delivers unmatched valvetrain durability. Built for 3/8-inch studs on cathedral-port LS engines, it withstands punishing valvetrain loads while reducing valve stem drag.
