Finally, here's an easy way to convert from hydraulic to solid liter cams. No longer will 7000 rpms be the practical rev limit! So long as internals are properly prepared, the rev band may be extended an incredible 2k rpms or more.
These solid racing lifters are enhanced with DLC (Diamond-Like Carbon) coating for radically improved wear resistance. Build material is SAE 4120 alloy with a face hardness of Rockwell 52. Foot measurement is 14.50 or 17.50mm to work with standard-length valves. Valve/cam lash adjustment is done by machining the base to the desired clearance. Pick which ever length is closer to (but not under) this required "shim" amount.
Benefit from ease of set up now and durability over time. Just combine with a pair of solid lifter racing cams and get the revs boiling!
Note: It is a good idea to pick up a few extra lifter feet to avoid down time in case of machining error.
