SBC R/Z Roller Lifters - .185in Offset

The ISKY CAMS SBC R/Z Roller Lifters with .185-inch offset are precision hydraulic roller lifters designed specifically for small-block Chevrolet engines. These lifters cater to serious engine builders and hot rodders who require reliable valve actuation under extreme RPM and high-lift conditions. Their engineering ensures optimal performance in demanding applications.

The roller lifters feature an offset design that compensates for specific cam lobe geometry, ensuring proper oil delivery and stability. Constructed from hardened steel with precision-ground roller wheels, these lifters reduce friction compared to flat-tappet designs, allowing for higher RPM capabilities and extended engine life. The .185-inch offset is crucial for maintaining proper pushrod geometry and preventing binding during valve train cycles.

These roller lifters are ideal for applications such as street performance, bracket racing, and both naturally aspirated and turbocharged small-block Chevrolet builds. Engine builders must verify cam lobe offsets to ensure compatibility, as pairing with non-compatible profiles can lead to inadequate oil supply and increased wear.
