WEB-CAM is probably the most important manufacturer of racing camshafts worldwide! For over 30 years, racing teams from all over the world have relied on WEB-CAM products. These STAGE 3 camshafts for all GPZ 900 R and GPZ 1000 RX are racing cams for top-end performance. The use of HIGH PERFORMANCE valve springs and shims at the bottom is absolutely necessary. Excellent camshafts for racing engines! To produce these camshafts, the lobes are welded on and re-ground. For this we need your used parts. Please make sure that the bearings are in good condition.
