These springs replace the Kibblewhite springs that are prone to breaking. These springs will work with the Kibblewhite spring seat and retainer. They will also work with the Kibblewhite SIT bucket setup. If your interested in running any boost please check out our SIT HD spring kit. That kit contains our HD springs along with the SIT buckets.

We recommend putting new valve seals in at this time because the inside spring on the Kibblewhite springs wears on the valve seals.
