The best ATV front wheel hub depends on your axle diameter, wheel bolt pattern, brake setup, and vehicle model. RUTU suits many Chinese 4-stud disc-brake ATVs, PRO BAT offers a 17mm-axle hub, and LenvraSQ is a pair with pre-installed bearings. Amavoler covers a 15mm-axle replacement, while JAVIK is designed for a range of Polaris models. Confirm measurements and fitment before ordering; a similar-looking hub may not match your ATV.
| Product | Best For | Key Fitment Detail |
|---|---|---|
| RUTU 4 Stud Hub | Chinese ATVs with disc brakes | 4-stud pattern; listed rim measurements |
| PRO BAT Hub | 17mm axle replacements | 4-bolt rim; 78mm bolt spacing |
| LenvraSQ Pair | Two-hub replacement | 17mm axle; 110mm lug spacing |
| Amavoler 15mm Hub | Kazuma Meerkat 50 fitments | 15mm inner diameter |
| JAVIK Polaris Hub | Listed Polaris ATV models | Model-specific fitment list |
RUTU 4 Stud Front Disc Brake Hub
Best for: Owners of compatible Chinese or Asian ATVs and go-karts that use a four-stud front disc-brake hub. The listed examples include Tao Tao ATA150D, 150HW, 150GK, Rhino 250, and Bull 150.
The steel hub is described as precision-machined and made for impact and wear resistance. Listed rim measurements include a 90mm center hole, four mounting holes, and 110mm criss-cross or 80mm straight-across bolt spacing. The product also includes steering knuckles, according to its name.
Check before buying: Confirm your wheel measurements, mounting bolts, and vehicle fitment. The broad compatibility description does not establish fit for every ATV from those brands.
PRO BAT 17mm Axle Front Hub
Best for: Buyers whose ATV, UTV, quad, buggy, or similar vehicle uses a 17mm front axle and a compatible four-bolt rim. The listing names engine sizes from 50cc through 250cc, but axle and wheel specifications remain essential checks.
This steel-alloy hub has a 17mm bearing hole and a stated 78mm bolt-to-bolt space. The manufacturer describes it as forged and heat-treated for hardness, strength, and wear resistance. Choose it when those measurements match your existing assembly.
Check before buying: The listing’s 4-bolt rim reference and 78mm spacing should be compared with your wheel’s actual pattern. Displacement alone does not confirm compatibility.
LenvraSQ Pair Of 17mm Front Hubs
Best for: Riders needing a pair of front hubs with pre-installed bearings for a 17mm axle and a matching four-lug wheel. The listing cites 7- to 10-inch wheels and ATV, go-kart, UTV, buggy, and trike applications.
The stated lug spacing is 110mm, or 4.33 inches. Its pre-installed bearings are described as supporting smooth rotation. This option is better suited to a buyer who needs two hubs rather than a single replacement.
Check before buying: Verify the axle diameter, wheel size, and four-lug spacing. The listed vehicle categories are broad and do not guarantee fit on a particular model.
Amavoler 15mm Front Hub
Best for: Buyers replacing a hub on a listed Kazuma Meerkat 50, 50cc ATV, or compatible Coyote go-kart application that requires a 15mm inner diameter.
This aftermarket replacement is made from metal, and the listing identifies its inner diameter as 15mm. Choose it when that measurement and the application match your current part; it is not interchangeable with the 17mm options above based on the supplied specifications.
Check before buying: The listing asks buyers to confirm the pictured dimensions and compatibility. It provides fewer detailed wheel-pattern measurements than some other options here.
JAVIK Front Hub For Listed Polaris Models
Best for: Polaris owners whose exact ATV model and year appear in the fitment list. Listed vehicles include selected Sportsman, ACE, ATP, Hawkeye, Magnum, Scrambler, Trail Blazer, and Trail Boss models.
The hub and bearing assembly is described as forged from high-strength aluminum alloy. The listing also specifies class 12.9 wheel studs made from SCM435 alloy steel. This is the most model-specific choice in this group, so use the vehicle fitment details rather than general size assumptions.
Check before buying: Fitment varies by model year and configuration. The listing excludes some versions, including Sportsman 6×6 and Magnum 330 2×4, so verify the exact application.
Buying Guide: How To Choose An ATV Front Wheel Hub
Which measurements should I check?
Start with the axle or bearing inner diameter, then measure the wheel’s lug pattern and center hole. Note the number of studs and the distance between them. A hub with a 17mm axle opening will not match a 15mm axle simply because both parts are described as ATV hubs. Compare measurements against the original part or vehicle service information.
Does the brake style matter?
Yes. Confirm whether your ATV uses a disc-brake or drum-brake hub and whether the replacement matches that arrangement. The RUTU listing specifies a front disc-brake hub, while several other listings name drum-brake assemblies. Brake layout and mounting details must match the vehicle.
Should I buy one hub or a pair?
Check the quantity and side designation in the product listing. The LenvraSQ option is sold as a pair. A single-side replacement may be appropriate for one damaged hub, but confirm left or right orientation where specified. Some drum-brake listings identify a side explicitly, so do not assume every assembly is interchangeable.
How do I confirm vehicle compatibility?
Match the make, model, year, and configuration—not just engine displacement. Then compare axle diameter, wheel bolt pattern, brake type, and any listed dimensions. If your measurements or vehicle variant are unclear, consult the seller or a qualified mechanic before installing a replacement.
Frequently Asked Questions
Can I choose a front hub by ATV engine size alone?
No. Engine size is only one clue. Axle diameter, lug pattern, brake style, and exact vehicle fitment must also match.
What does a 17mm hub measurement refer to?
For the products listed here, 17mm describes the axle or bearing-hole diameter. Confirm that this is the measurement required by your ATV.
Are four-stud hubs all interchangeable?
No. Four studs do not guarantee the same bolt spacing, center hole, axle fit, or brake configuration.
Do these options include bearings?
The LenvraSQ listing specifies pre-installed bearings, and the JAVIK product name includes a bearing. Check each product’s listing for the exact included components.
