No more worn cam lobes or broken rockers. This kit is proven to be extremely durable and reliable for sustained high RPM. BMW Series M20 6 Cylinder engines.

Roller cams offer superior valve opening speeds allowing more aggressive profile with higher lift, increasing power potential while maintaining good mid range torque. Needle bearings and rolling contact lowers the friction loss increasing power and reducing the load on your cam belt. There is simply nothing better!

Every item in this kit is made from the highest quality Aircraft grade materials. Cams are Made in Sweden from high grade case hardened tool steel and ground on one of the most hi-tech cam grinding machines available, one of very few in existence that can produce the unique tight inverse lobe design needed to make this conversion work so successfully.

Valve springs are high performance Australian made for Porsche race engines topped lightweight titanium retainers. Rockers are precision machined from high tensile 7 series aircraft aluminum and fitted with genuine Porsche valve lash adjusters, Swedish SKF needle bearings keep it all together. Serviceable pins and rollers are made from crome-based bearing steel then case hardened and center-less ground to a mirror finish.
