Looking for a Big Power Boost for your ’99-’06 Twin Cam? Zipper’s Muscle 107 kit will double the HP of a TC 88” engine – all while looking stock from the outside! A new 4-3/8” stroke crankshaft replaces the original 4” crank, while your cylinders are decked and precision fit with 3.937” 10.6:1 pistons. Your heads receive Zipper’s Stage III CNC porting with new guides, oversize valves, performance springs and manual compression releases. Our Red Shift 577 cams provide big torque & HP gains across the entire RPM range. Also included are Pro-Taper pushrods and EZ-Adjust covers, with all gaskets needed for assembly. Highly recommended option: Zipper’s #417-495 blueprinted cam chest upgrade with our Red Shift Dual Piston hydraulic cam chain tensioners, blueprinted billet plate, HV oil pump, cam bearings and quality USA lifters for improved reliability and durability. Amazing New Life for the 1st Generation Twin Cam® – M8’s BEWARE!
