The Super-Hammer delivers BIG POWER without the complexity of building a big bore engine. The Super-Hammer 1200 is a top end and cam kit, supplied with extensively modified big-valve heads that have received the full Zippers CNC porting treatment. After porting, the heads are fitted with Step-Lock guides, oversize valves, Viton® seals and high performance springs with titanium collars. The cylinders are torque-plate honed and precisely fitted with forged 10.5:1 pistons, and Red Shift 567 cams are installed and timed on the factory cam gears. Chrome moly pushrods, a telescoping pushrod cover kit and a top quality gasket kit are supplied for re-assembly. To provide proper fuel and ignition curves, a Mikuni HSR42 carburetor with a Zipper’s High Flow air cleaner and Zipper’s adjustable ignition are included, set up for the kit.

This kit is ideal for the Sportster owner who wants a true max output 1200, suitable for everyday use. Excellent power throughout the entire RPM range is what this kit offers; we’ve applied our extensive experience in cylinder head and camshaft design to this package for Torque And Horsepower That Is Head And Shoulders Above The Rest!

These kits are available from any Zipper’s Performance Products dealer, or you can send your carefully packed parts directly to Zipper’s. 2004-06 models: Send cams, cylinders and heads for modification. In-shop time is generally 2-3 weeks. Please pack your parts carefully!
