When adding a performance kit with large increases in power or conducting a full rebuild on an engine to assure reliability, the Engine Experts at Zipper’s can help build a fresh short block with your cases.

Zipper’s offers short block services with new stronger forged steel cranks from Dark Horse or S&S

Note- The straight roller bearing design was upgraded in 2007 and has proved very durable on many high output engines.  Yet if you feel your project requires a Timken tapered bearing system we can machine your case for the Timken system.
