SR Crank Lock up Kit

The HRB SR Crank Lock Up Kit is the professional solution for securing the crankshaft during critical engine operations. Whether you’re removing or torquing the crankshaft pulley bolt, installing or removing the flywheel, or assembling a bottom end, this precision-engineered kit simplifies the job and protects your engine from costly mistakes. Designed specifically for the NISSAN SR20 engine family, it provides three secure locking methods to suit any build environment, from the engine stand to in-car applications.
