Frequently Asked Questions

What does this O-ring kit replace?

The factory rubber O-rings that seal the pushrod tubes on Evo Sportsters. These harden and shrink with age, causing oil leaks.

How difficult is installation?

Pushrod O-ring replacement requires removing the rocker boxes and pushrods — a moderate DIY job or 1–2 hours at a shop.

Will this stop an active pushrod leak?

Yes. If your Evo is weeping oil around the pushrods, new Cometic O-rings will restore the seal when installed correctly.

Does this fit my year Sportster?

This kit is designed for Evo Sportster models. Confirm your bike has evolution-style pushrod tubes before ordering.
