High-strength piston kit engineered for use in 80" Stock Big Twin motors.

Each kit includes a complete set of pistons, rings, wrist pins, and retaining clips for a straightforward installation.

Wrist pin deck height is 1.270". The kit requires connecting rods with a rod length of 7.440"; use of earlier 7.470" rods can slightly increase compression and may create clearance issues — check piston-to-cylinder head clearances carefully.

Made in the U.S.A. 🇺🇸
