When high-performance engine modifications are made, the increased torque is transferred via the crankshaft to the drive system, putting a significantly higher load on the bearing. The Lefty Bearing is case-hardened on the inner and outer race to provide increased load capacity and enhanced durability in high-torque applications. The bearing is installed in the left side of the crankcase, and supports the output shaft to the primary drive system.

A cost-effective alternative for upgrading the performance of your bike. The intake and exhaust ports are meticulously machined to smooth the surfaces, enhancing the flow characteristics of air and fuel to provide enhanced performance. But it doesn't stop there: oversized (1.875") stainless steel intake valves and stock (1.575") stainless steel exhaust valves rest in reshaped valve seats that improve flow rates. The combustion chambers have been machined to smooth the surface, and feature a blended radius on the bathtub's edge to reduce detonation by eliminating hot spots and promoting improved combustion. The head gasket surface has been milled to maintain stock combustion chamber volume, which results in stock compression when used with Original Equipment pistons. Compression can be increased with the installation of matched Screamin' Eagle high compression pistons. Heads are assembled with high performance valve springs that support cams with lift up to.585".

These performance Beehive-shaped valve springs provide increased stiffness and strength in a compact design. Designed to support the installation of higher lift cams, these performance springs help maintain the stability of the valve train in high RPM conditions. When compressed, these valves have a higher rate of stiffness to keep the valves from bouncing off the valve seat or "floating" during aggressive throttle application. Kit includes 8 springs, upper collars and keepers and lower collars with integral valve seals.
