Product Description

The **Brian Crower BC2945** is a set of high-strength, 6° billet valve keepers designed for the Nissan SR20DE and SR20DET engines. These keepers are machined from chromoly steel and heat-treated to withstand the rigors of high-RPM or performance applications, reducing the risk of valve retainer failure or keeper shear.

With a set of 32 (for 16 valves), BC2945 provides a reliable and lightweight solution for both stock and upgraded valvetrains. They are fully compatible with BC2200 retainers (as well as many OEM variants), making them a popular choice for engines where increased reliability is needed - especially for tuned or high-stress builds.
