Compression Release Kits

This category groups the compression release kits essential for Harley-Davidson and American custom engines. These sets typically include the release shaft, rocker arm, spring, and necessary seals to facilitate engine starting.

About this category

They are fundamental components for families such as Evolution, Twin Cam, and Milwaukee Eight, as well as for Sportster, Dyna, Softail, and Touring models. The kit slightly opens the intake valves during starting, reducing mechanical resistance. Ideal for preventive maintenance, repair after wear, or installation in rebuilt engines. Compatible with Flathead, Knucklehead, Panhead, and Shovelhead engines depending on the reference. Ensures smooth and reliable starting for your motorcycle.
