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.

Kit Contents:

• Engine stand lock — locks the crankshaft directly through the rear of the crank when mounted on an engine stand
• Starter motor hole mount lock — engages the flywheel ring gear for strong crank locking without disassembly
• Bellhousing mount lock— bolts to the back of the block to engage the flywheel when engine stand use isn’t possible
• Required mounting hardware included
• Wall organising mount included for clean storage
