Micro Surface Enhancement

COMP Cams® is the first in the automotive aftermarket to employ a new camshaft finish technology for increased strength and performance that far exceeds traditional polishing.

Micro Surface Enhancement™ (MSE) is a finishing process that improved the traditional camshaft lobe and bearing journal through a 65-percent reduction in surface peak roughness and provides a 250-percent improvement in the effective load bearing area. Spreading the contact area between the roller and cam face allows for much higher loads and lower localized stress. Additionally, MSE utilizes uniform pressure across the camshaft lobe face that reduces the surface waviness common with other finishing techniques, such as belt polishing. The resulting camshaft surface more evenly distributes load for increased durability. MSE also removes the sharp edges and microscopic machining marks that normally result from the grinding process.

The MSE process is now standard on all COMP Cams® GM LS camshafts.
