Spring is here - Pump Up the Power in your Twin Cam with a Zipper’s big bore exchange cylinder kit! Zipper’s has Twin Cam cylinders that have been treated to a precision boring and honing process in our Rottler CNC hone, on torque plates for a straight and true finish requiring minimal run time for ring seating.

Wiseco forged pistons with moly-coated skirts are as tough as they come, and each kit is supplied with a complete top end and cam change gasket kit. Kits are available in silver, black with highlights or all-black (Cross Bones) finish.

Three different compression ratio pistons are available for both 88” to 95” or 96” to 103” conversions, to perfectly meet your cam or cylinder head requirements.

Minimize downtime using the exchange program – No Waiting!
