Profile: Kemko, Inc is a supplier of air filter and oil filter elements. We also distribute exhaust manifolds & expansion joints, engine & compressor parts, piston rings and compressor lubes. Our shock dampers are used to dampen shocks. Our damper simplifies engine balancing and virtually eliminates maintenance costs through less valve train wear. It is not a hydraulic lifter, and as such does not eliminate clearance as does a hydraulic lifter. It is interchangeable with the original equipment adjusting screws.
