New halves, new pin, new rollers, new H beam rods, set to our clearances. Plugged with solid steel plugs and welded to prevent twisting. Assembled and trued, no core charge needed. Outright purchase, custom balancing for big bores and different combos. Factory balance off the shelf or custom balance to your total piston weights complete including pins, clips, and rings. Add a few days to balance and assemble. The early 2000-2006 4 3/8 is a stroker to make your 88” into a 107” powerhouse. 4 5/8 stroke matched with S&S 124 (4.125 bore piston kit, Requires Case Boring) makes a great 124 combo!
