Zippers Oiling System Upgrade Kit

This direct replacement product is designed to improve cam timing and valve train control on all 2007-up Twin Cam engines and 1999-2006 engines equipped with hydraulic chain tensioners.

The Axtell oil bypass valve is machined with a needle and seat that inserts in place of the factory oil pressure relief valve located within the twin cam plate. Reducing foamy and aerated oil results in lower oil and engine temperatures equalling longer engine life. Go to zippersperformance.com for more info.
