Axle Housings & Parts
About Axle Housings & Parts
Axle housings, carriers and hubs hold a quad's rear axle in the frame and connect it to the wheels and the chain drive. The listings here are mostly for sport quads, with sprocket hubs, axle carriers, axle nuts and housings named for the YFZ450, Banshee, TRX450, Raptor 700 and Honda 250R. Riders shop for them after crash damage, a worn or stripped axle nut, or when changing sprocket setups.
Fit is by model. An axle carrier holds the bearing at the end of the rear axle in the swingarm, and a sprocket hub mounts the rear sprocket to the axle. Hubs are listed in steel and aluminum. Axle nuts are listed by size, such as 18 mm, 20 mm and 3/4-16, and there is a one-piece Posi-Lock style nut for the Raptor. Match the nut to the thread on your axle. Hubs and carriers are listed by model and should not be mixed between models.
Brands in this category include Lone Star Racing/Tech 5 Ind. and Dura Blue. Related parts are in Axles, Bearings and CV Axle Assemblies, and sprockets are part of Final & Primary Drive Parts & Kits. The whole group is Transmission & Drivetrain. Pick your machine in the Ride Finder at the top of the page to see parts made for it.
FAQs on UTV and ATV axle housings and hubs
How do I choose the right axle nut?
Match the size and thread to your machine instead of guessing. Listings state sizes such as 18 mm, 20 mm or 3/4-16. Your service manual gives the thread and the tightening torque, and some machines also call for a cotter pin or locking nut. Replace any nut with damaged threads.
What does an axle carrier do on a sport quad?
It holds the axle's bearing in the swingarm. On many quads the carrier is also where the chain tension is adjusted. Carriers are made for specific models, so choose the one listed for your quad and check that the bearing and spacing match.
What does a sprocket hub do?
The sprocket hub bolts to the axle and carries the rear sprocket, so it passes the chain's drive to the axle. Listings here include steel and aluminum hubs. Check that the hub suits your axle and your sprocket's bolt pattern before ordering.
When should an axle housing be replaced?
Replace a housing that is bent, cracked or has damaged bearing or mounting surfaces, because it throws off axle and chain alignment. These problems often follow a crash. If you cannot tell whether a housing is straight, have a shop check it.
Can I use a sprocket hub from another model?
Only if the listing says it fits your model. Hubs can differ in axle diameter, spline and sprocket bolt pattern, and a poor fit can damage the axle. Use the model range in the listing as your guide.
