The Elgin SSR-1840SPRS is a high-performance engine rocker arm set engineered for optimal functionality and precise valve operation. Constructed from polished stainless steel, these full roller rocker arms offer enhanced durability and performance. They feature a 1.6:1 ratio, a self-aligning design, and utilize poly lock nuts for secure mounting. Designed for stud mounting, these rocker arms have a 0.438-inch stud thread diameter. The marketing description highlights their ability to boost engine power and performance through superior valve control, contributing to increased efficiency. The set is boxed as 16 pieces. These rocker arms are application-specific and are compatible with a wide range of Chevrolet, Buick, and GMC engines, primarily small block V8s, from the mid-1950s through the early 2000s. Specific fitment includes engines like the Chevrolet 350CID (5.7L) from 1966-1997 and the Buick 350CID (5.7L) from 1966-1997, among many others detailed in the application list.
