The Harrop Crank Pinning Kit makes it easy to add additional security for your supercharged LS series engine.

It is recommended that all supercharged LS engines have their crankshaft and balancer either keyed or pinned. Some aftermarket crankshafts and balancers come with keyways machined into them whilst the OE engines do not, If they are not secured the harmonic balancer may spin on the crankshaft and cause damage to the crankshaft and balancer.

The kit will enable to you precisely drill your crank and balancer for fitment of a locating pin.

Vehicle Applications: All vehicles fitted with GM LS Series engines.
