Moog K8834 Rack and Pinion Bellows Kit

Rack and Pinion Bellows Kit for Ford and Mazda

The Moog K8834 rack and pinion bellows kit is built for steering systems that need a direct-fit replacement boot with the right dimensions and material characteristics. It is a practical choice for maintaining protection around the rack and pinion assembly on applications such as Ford Ranger, Ford Explorer, and Mazda B-Series trucks.

Moog continues to refine chassis components with design updates that improve service life and make replacement easier. The K8834 follows that approach with a nitrile bellows design, included hardware, and included ties for a cleaner installation on compatible steering applications.

Installation Notes and Tips

Verify the rack and pinion boot dimensions before installation, including the large end diameter, small end diameter, and overall length. Confirm the vehicle application against the fitment list for your Ford Ranger, Ford Explorer, Mazda B3000, Mazda B4000, Mazda B2500, Ford F-150, or Mercury Mountaineer. Use the included ties and hardware during installation to secure the bellows properly and maintain a tight seal at both ends.
