Frequently Asked Questions

Will this fit my 1991+ Sportster?

No — this shoe is specific to 1980–1990 Sportster XL models. Post-1991 Sportsters use a different tensioner design.

What does a primary chain tensioner do?

It maintains the correct slack in the primary chain to reduce noise, prevent chain slap, and extend chain life.

Is this a direct bolt-on replacement?

Yes — it replaces the factory tensioner pad without additional modification or special tools.

How often should I inspect it?

Check every 5,000 miles or annually. Replace if worn, cracked, or if primary chain noise increases.
