Stage 1 and Stage 2 performance camshafts are drop-in cams that are designed to be used with stock valve springs
In most applications, Stage 1 cams deliver more torque and Stage 2 cams provide more peak horsepower
Gold Series camshafts are designed to provide extra torque and horsepower; these camshafts require the use of stiffer valve springs
Select cams feature Hot Cams Improved Throttle Design (ITR) technology; these cams improve throttle response throughout the entire rpm range while providing excellent power gains through the mid-range and top-end
New Builder Series camshafts offer engine builders a multitude of options for different engine configurations
Builder Series camshafts were developed for engine builders that have specific requirements to maximize their particular engine configuration; see notes in the performance description for use with OE valve springs or the requirement of stiffer valve springs
Off-road competition use only. This cam replaces the 2047-1IN. It has better low RPM torque, pulling power, and throttle response. For best results it should be used with the 2050-1E exhaust cam. Uses stock DRZ400 valve springs
