Why Choose DLC Coated Rocker Arm Shafts?

The Uma Racing Rocker Arm Shafts (02RS0003) are a vital supporting modification for engines equipped with high-performance parts like the Uma Racing High Lift Camshaft. High-lift profiles increase the pressure on valvetrain components; the DLC coating addresses this by providing an incredibly low-friction surface that reduces drag and heat buildup. This results in more consistent valve timing and better protection against terminal engine wear during aggressive riding.
