The Brian Tooley Racing (BTR) LS Camshaft Retainer Plate is engineered to fit behind the front cover and provide a reliable seal for the front oil passages that supply oil to the lifters, camshaft, and main bearings. Designed for durability under increased cam loads, the plate features a specially designed gray O-ring to maintain a tight, leak-free seal.
Compatible with high-performance applications, this retainer plate is functionally similar to GM part #12589016, providing enhanced reliability and longevity in demanding LS engine builds.
