Common questions
Will this fit my 2007-up Harley with an automatic primary tensioner?
Yes, this Hayden shoe is designed to work effectively with both earlier 1965-2006 stock manual adjusters and 2007-up automatic tensioners, preventing over-tightening in either setup.
What common problems does this tensioner shoe address?
It helps eliminate excessive primary chain slack, which causes clunking, rough shifting, and premature wear on primary components. It also prevents the over-tightening issues seen with some stock adjusters.
Is this a simple bolt-on replacement?
Installation involves accessing the primary drive and replacing the existing tensioner shoe. While straightforward for experienced mechanics, we recommend consulting your model's service manual for specific instructions.
