Adjustable Cam Timing Gear - Volvo B21 / B23 / B230 1976-92

IPD adjustable cam gear provides the edge in performace for your B21, B23 or B230 engines from 1976-1992. Adjustable in 2.5 degree increments up to 10 degrees, either advance or retarded, and it weighs less than half the factory gear! A fixed single piece, this gear is adjusted by lining up the desired inscribed timing mark with the factory timing mark and placing the corresponding dowel hole on the cam. This should not be confused with ignition timing. By advancing the gear you will gain low end power at the expense of upper range power and by retarding the gear you will gain upper range power with a link reduction in low end power. This gear provides the widest range of adjustment from high RPM turning race engines to the big bore non turbo motors with lots of low end grunt!. Our gear is hard anodized for long lfe and tested for durability. A perfect match for our VX and Turbo performance camshafts or even use it with your stock cam. Suited for the belt with retangler teeth.
