Our dna adjustable engine cam gears increase horsepower and torque without having to change the camshafts and are must-have items for engines that are milled, forced induction, high compression and utilizing aftermarket competition cams. Our gears enable users to match cam timing with their vehicle's tuning state by advancing or retarding the cam profile in one-degree increments via true laser-etched markings. Precision-cut gear teeth ensure no premature wearing of the belt surface.

The dna adjustable cam gears fit of the inner and outer cam gear sections is the most critical part of cam gear machining. any looseness between these sections (not the sliding movement but the side to side movement) will cause the bolts to come loose, no matter how much they are tightened. dna racing gears fit very tight, every time, guaranteeing our gears will not come loose as long as they are torque to the specs in our instructions. Timing tooth shape is also extremely important for timing accuracy, long term reliability of the gear teeth and the timing belt. dna racing tooth profiles match or are better than original gears. The outer section of our gears are hard black anodized to prevent wear from the timing belt.
