C4 Fabrication Swing Arm Carrier Bearing Rebuild Kit

The C4 Fabrication Swing Arm Carrier Bearing Rebuild Kit supplies the four wear components needed to rebuild the bearing assembly on a C4 Fabrication swing arm carrier: two dust cap seals, two sleeves, two bearings, and one bolt. Bearing races are permanently affixed to the swing arm during manufacturing and are not included in this kit. One kit services a single swing arm; owners of dual-swing setups will need two kits.

Restore Smooth, Reliable Swing-Arm Operation

Swing arm carriers take real punishment: repeated loading and unloading, trail vibration, and exposure to mud, water, and road grit all wear the bearing assembly over time. Replacing the dust cap seals, sleeves, and bearings with fresh components restores the smooth, controlled pivot that a properly functioning carrier depends on, and extends the service life of the carrier itself rather than requiring a full replacement.

The Right Parts, Nothing Extra

This kit includes exactly the components that wear and can be replaced: the two dust cap seals that keep contamination out of the bearing assembly, the two sleeves, the two bearings, and the single bolt. The races are left out intentionally. They are permanently affixed to the swing arm during manufacturing, so they are not a serviceable part and are not needed for a standard rebuild.

Made in the USA

C4 Fabrication manufactures this rebuild kit in the United States. Owners of dual-swing carrier setups should order two kits, one per swing arm, to complete a full rebuild of both pivot assemblies.

Specifications

Who This Is For and Isn't

This kit is for owners of C4 Fabrication swing arm carriers who need to replace the bearing assembly wear components (seals, sleeves, bearings, and bolt) to restore smooth pivot operation. One kit covers a single swing arm.

This kit does not include bearing races, which are permanently affixed to the swing arm during manufacturing and cannot be replaced separately. It is not a universal bearing kit and is intended specifically for C4 Fabrication swing arm carriers. Owners of dual-swing setups need two kits to service both arms.

Common Questions

Which C4 Fabrication carriers does this rebuild kit fit?

Specific carrier compatibility has not been confirmed in the available product data. Contact TerrainVault before ordering to verify that this kit matches your C4 Fabrication swing arm carrier model and generation.

Are bearing races included in this kit?

No. Bearing races are permanently affixed to the swing arm during manufacturing and are not a serviceable part. The C4 Fabrication Swing Arm Carrier Bearing Rebuild Kit includes only the components that can be replaced: two dust cap seals, two sleeves, two bearings, and one bolt.

How many kits do I need for a dual-swing setup?

A dual-swing carrier requires two rebuild kits, one per swing arm. Each kit contains the parts to service a single swing arm bearing assembly.

What tools or skills are needed to complete this rebuild?

Installation requirements are not specified in the available product data. Because this is a bearing rebuild on a load-bearing carrier component, consulting C4 Fabrication's instructions or a qualified installer before beginning the job is advisable.
