Twin Power Tension Reliever Manual Primary Chain Adjuster 07-16 FLH, FLT




An overtightened primary chain is known to cause premature failure of the engine, transmission and primary bearings as well as other complications. Usually, the factory automatic primary chain tensioner is the culprit. The Twin Power Tension Reliever helps prevent premature engine and transmission bearing failure by allowing proper chain tension of 5/8" to 7/8" free play when cold.
