Crower 66245-16 Features:

Crower 66245-16 severe-duty cutaway roller lifter set for Dodge R5 and Chrysler V8 340 SB NASCAR blocks; includes 16 lifters for complete engine build coverage. CNC-machined billet alloy bodies use a lightweight, heat-treated design to handle high cylinder pressure and sustained high-rpm racing applications. Crowned bearings and a crowned outer race help minimize lobe tracking, while longer control-contoured tapered needle bearings increase load capacity. Heavy-duty raised blades fit late-model blocks, and captive blades use Crower orbit-formed locking instead of snap rings for added reliability.
