The use of heavy dual valve springs and stock helical cut camshaft gears results in excessive side load on the cam bearing thrust shoulder. Straight Cut Cam Gears run without side load and solves the problem of early wear to cam bearing thrust surfaces. Steel-on-steel Straight Cut Cam Gears are an absolute must to stop cam bearing thrust wear when Chevy type racing valve springs are used. An added bonus is that Straight Cut Cam Gears run with less friction than helical cut gears and produce more power.

Straight Cut Cam Gears are also adjustable to enable you to dial in your cam timing. Each set is shipped with three sets of adjusting discs for cam timing.
