A COMP Cams 1.6 ratio shaft‑mount aluminum roller rocker built for Chrysler small‑block 273–360 V8 engines. The rocker arms ride on a durable shaft and use a high‑tensile aluminum alloy (80,000 psi); needle bearing trunnions permit valve spring pressures up to 350 lbs open. These shaft‑mount rockers replace the stock items from the 1074‑KIT and suit many street performance builds.
