Premium Shock Damper Rebuild Kits - Supplemental (FKM Upgrade Kits)

from $5.00

Built with premium FKM/Viton® dynamic seals for improved performance and reliability.

These custom seal kits were built to eliminate the premature failures and inconsistent performance of many shocks.

Supplemental kits only include dynamic/critical seals, perfect if you already have a standard/OE rebuild kit.

These are perfect to offer as an optional upgrade in your shop.

Each premium supplemental kit includes:

  • FKM sealhead seal(s) to prevent aeration from the air can, known issue with PU seals.

  • FKM IFP o-ring also to prevent aeration and significantly improve durability.

  • FKM SAG o-ring provides superior UV and chemical resistance.

  • FKM+ kits feature FKM X-rings for maximum reliability with even lower friction.

  • Sample packs include a sample of each of our popular supplemental kits. (Only for shops - limited to one pack per shop)

These service kits are more reliable than OE, while keeping the price low.

While reliability is our primary goal, FKM o-rings also reduce friction compared to Polyurethane seals. FKM+ further reduces friction.

Please consider you’ll need advanced skills, specialty tools and nitrogen equipment, always refer to the service manual.

Wholesale pricing available for bike shops and service centers, please reach out for details.
