Speedmaster Mopar Chrysler SB 318 340 360 1.5 Stainless Steel Roller Rocker Arms with Hardware PCE261.1084.01

The Speedmaster PCE261.1084.01 roller rocker arms are precision-engineered components designed for small-block Mopar Chrysler engines (318, 340, and 360 cubic inches). Built from durable stainless steel with a 1.5:1 ratio, these rocker arms deliver reliable valve actuation and improved engine performance. The complete kit comes with all necessary mounting hardware for straightforward installation.

Roller rocker arms reduce friction at the valve train compared to stock stamped steel designs, enabling better flow and more consistent valve timing across a wider RPM range. The stainless steel construction resists corrosion and provides long-term durability in high-heat engine compartments. These arms are ideal for street performance builds, restorations, and enthusiasts seeking improved reliability and efficiency in classic Mopar powerplants.
