Repl.Ring Set for 110 BigBoreSleeperkit

These Wiseco Big Bore kits are developed for Twin Cam 96 (1.550cc). The use of the 3 7/8" bore pistons with stock 4.375" stroke enlarges the capacity of your Twin Cam engine from 96 to 103CI (1.691cc). The 4" bore kits will even give you a 110CI displacement (1.802cc) but must be used with the use of cylinder sleeves in your stock cylinders. The 3 7/8" bore kits can be used in bored-to-size stock cylinders. Sleeves are not included but must be ordered separately. Big Bore piston kits contain a pair of Wiseco forged pistons, a Hastings ring set, chrome wrist pins and circlips.
