Our Racing Gland Nuts are made of chromoly steel, a strong and durable material that can withstand high stress and heat. The extra-large thrust surface helps hold the flywheel firmly against the crankshaft to prevent loose dowel pins and oil loss. The increased diameter has better holding power than stock gland nuts. Complete with inner needle bearing and special grease seal. You can use Racing Gland Nuts with stock or lightweight flywheels with 4 or 8 hole pattern. Includes a hardened steel thrust washer for added strength and holding power. For use on all 40hp, 1300, 1500 and 1600cc based engines.

NOTE: Requires 1-1/2" socket.
