Flywheel Kit, Ultra-Lightweight Steel, TR6 1970-76

Description

This lightweight steel flywheel made by Bastuck weighs only 12.5 lbs with ring gear fitted while the stock flywheel with ring gear weighs approximately 27.25 lbs.  Reducing the weight of the flywheel allows the engine to rev faster, increasing throttle response and acceleration.  Includes clutch pressure plate bolts, dowel pins, starter shim and ARP flywheel bolts.  Flywheel is supplied with the ring gear installed.

Steel flywheels have a more reliable attachment to the crankshaft than aluminum flywheels.  Aluminum flywheels are hard to keep tight on the flywheel due to the softer flywheel material and dissimilar expansion rates of aluminum vs the steel crankshaft.

This flywheel works well on a race engine where fast rpm changes are needed.  For smoother operation in a high performance street application you may prefer our 16.7lb (with ring gear) premium grade lightweight steel flywheel kit (SKU 6346K)

Ring gear position with this flywheel is about .090″ closer to the engine than original.  A starter shim is included to correct the starter gear engagement.  Failure to use a starter shim may result in starter damage due to failure to disengage from the ring gear when the engine starts.
