The use of dual high-lift 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 solve 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 and high-lift camshafts are used. An added bonus is that
Straight Cut Cam Gears run with less friction than helical cut gears and require less HP to drive.
CBP Straight Cut Cam Gears are also adjustable to enable you to dial in your cam timing. Includes Grade #8 bolts and three sets of adjusting discs - 0, 2 and 4 degrees. Manufactured in the USA from Forged Chromoly.
