P22 adjustable cover allows you to adjust engagement of your P22 through the use of detents. With no detents, it operates as a factory cover. With 3 detents screwed in raise engagement 300-400 RPM. With 6 detents in, engagement will raise 600-800 RPM.  The detents only adjust engagement, once out of engagement, they do not affect any other shift properties. This cover is able to be used as a trail cover ONLY if you remove all detents. The detents were designed to use in drag racing only applications, and are a wear component that will have to be replaced periodically. They will be available on the website. This kit comes with the cover, (6) detents, new center shaft, center shaft shims, and a 3/32 t handle tool to install and remove the set screws.
