Description

These kits include a new wipers, nut seal, keys, lower bumper, as well as upper and lower bushings. The kit also includes a small amount of Grease as required for the rebuild. Use this kit if your post is getting worn, your wipers are torn/worn out, or if you have started to leak air from the main nut.

The kit also includes a replacement urethane Air Cushion and Retaining Ring. It can be used to replace a metal air cushion (retired) or a worn urethane one.

This kit is ONLY for Fall Line seatposts with the v1 Collar Nut. Use this kit only if you are replacing the v1 Collar Nut with the v2 Collar Nut (RECOMMENDED). There are other kits available if your post has a v2 Collar Nut.

All of the parts and components have been designed and tested by our professional engineers and meet a high standard of quality.  These parts have been tested in our lab and on the trails, in spring, Texan summer, fall, and the Canadian winter. Be cautious of rebuild kits offered by other vendors as they may not be of sufficient quality and could void your warranty.

See the Specs tab for a list of the Kit Contents.
