A 4/137 bolt pattern means four lug holes arranged on a 137 mm bolt circle. It does not identify every wheel that will fit your UTV. Start with your exact model year, trim and current hubs, then verify the wheel manufacturer's application, dimensions and required hardware. The examples below show why buying by brand name alone can send you to the wrong pattern.
- Read both numbers: lug count and bolt-circle diameter. 4/137 and 4/156 are different patterns.
- Do not choose a pattern from “Polaris RZR” or “Can-Am Maverick” alone. The exact model and year matter.
- Check center-bore clearance, wheel size, offset, brake clearance and mounting hardware as well as the pattern.
- A pattern adapter changes the mounting interface and wheel position. It needs its own application and installation checks.
- The sourced KRX 2020–2023 example below is four-lug 4/156. Do not order a five-lug wheel from the KRX name alone.
Why this matters
A matching wheel design or finish tells you little about hub fitment. Two wheels can look identical while using different drilling, offsets or mounting hardware. Before buying through R1 Industries, compare the exact selected variant with your vehicle and intended tire setup.
Do not use tightening force to make an unverified wheel fit. If a wheel does not mount correctly, stop and have the application checked before installation or riding. A matching bolt pattern is only one part of the decision.
How to match bolt patterns when buying UTV wheels
Use these five checks before choosing a wheel:
- Identify the exact vehicle and hubs. Record model year, model, trim and any hub, portal, brake or suspension changes. Consult vehicle-manufacturer documentation and the wheel maker's application information; an authorized dealer can help resolve missing specifications.
- Read the pattern and units. The first number is lug count; the second is bolt-circle diameter. A 5x4.5-inch pattern equals 5x114.3 mm. Do not confuse wheel diameter in inches with bolt-circle diameter.
- Match the intended mounting interface. A four-lug wheel is not a direct fit on a five-lug hub. Check the exact SKU rather than relying on a photograph or a brand-wide fitment label.
- Check the bore and hardware. Verify hub clearance, the intended centering method, lug-seat style and stud thread. Hub-centric and lug-centric designs exist; follow the wheel manufacturer's requirements rather than assuming all wheels center in the same way. See Wheel Pros' explanation of wheel centering.
- Confirm the complete wheel-and-tire fit. Check wheel width and diameter, offset/backspacing, load requirements, brake and suspension clearance, and clearance through steering and suspension travel. Confirm the tire maker's approved rim dimensions. See the checks in Valor Offroad's manufacturer fitment guide.
A bolt pattern adapter is a separate fitment decision, not automatic approval to use any wheel with a different pattern. Confirm the adapter's specified vehicle, hub-side and wheel-side patterns, hardware and installation requirements. Have the resulting wheel position and clearances checked; do not assume an adapter is suitable simply because its two pattern numbers match.
Year-specific UTV bolt-pattern examples
These are examples from a wheel manufacturer's application catalog, not a complete current-year fitment chart or approval for every wheel of that pattern. Verify your exact vehicle and chosen SKU before purchase.
| Vehicle example | Model years in source | Listed bolt pattern |
|---|---|---|
| Can-Am Maverick X3 | 2017–2023 | 4/137 |
| Polaris RZR Pro XP | 2020–2023 | 4/156 |
| Polaris RZR XP 1000 | 2014–2023 | 4/156 |
| Polaris RZR Pro R / Turbo R | 2022–2023 | 5x4.5 inches (5x114.3 mm) |
| Kawasaki KRX | 2020–2023 | 4/156 |
| Yamaha YXZ 1000 | 2016–2018 / 2019–2023 | 4/110 / 4/156 respectively |
Source: System 3 Off-Road 2023 catalog, application pages 14–18. Its KRX listing specifies 15-inch and larger wheels within that catalog. This does not establish clearance for every other wheel design.
Confirm fitment before installation. Never use lug-nut torque to force an unverified wheel onto a hub.
4/137 Pattern: Which UTVs Use It
4/137 appears in Can-Am wheel applications, including the X3 example above. Zollinger Racing Products' Can-Am Apex wheel is another manufacturer listing for an X3 application using 4x137. That does not make every 4/137 wheel suitable: width, offset, bore, hardware and clearance still need to match. Do not apply this pattern to every RZR or every Can-Am model.
4/156 Pattern: Which UTVs Use It
4/156 appears in the four-lug Polaris, Kawasaki and later Yamaha examples in the table. Read the complete model name: a Pro XP application is not the same as a Pro R application. For example, R1 lists Apollo beadlock wheels for the RZR Pro R separately. Match the exact selected variant to your vehicle before ordering.
4/136 and 4/137: read the wheel maker's application
Some manufacturers use a combined 4x136/4x137 label for a specified wheel application. For example, Metal FX's Delta Beadlock lists certain Can-Am/Honda variants that way. This is product-specific manufacturer fitment information, not a rule that any two wheels labeled 4/136 and 4/137 are interchangeable. If a listing and vehicle specification differ, confirm the exact SKU and application with the manufacturer or R1 before buying or mounting it. Do not infer that an adapter is always required, either.
5/114.3 Pattern: Which UTVs Use It
5x114.3 mm and 5x4.5 inches describe the same five-lug bolt circle. The Pro R/Turbo R example in the table uses this pattern. Five-lug and four-lug RZR applications must be checked separately. A shared bolt circle with a wheel intended for another vehicle does not establish suitable bore, offset, load capacity or brake clearance.
Why the model year and full model name matter
- A brand can use several hub patterns across its lineup. Start with the full vehicle identification, not the brand alone.
- Model generations can change fitment. The two YXZ year ranges in the table illustrate why the year belongs in your wheel search.
- Aftermarket hubs, portals, brakes and suspension can change what fits your particular vehicle.
- Similar model names do not mean shared fitment. Check Maverick X3 and Maverick R separately: Metal FX's Maverick R application lists a six-lug 6x139.7 wheel.
- Keep the selected wheel SKU, size, offset and hardware specification with your order so the installer can verify the complete setup.
Can I put 4/156 wheels on a 4/137 hub?
They are different four-lug patterns, separated by 19 mm in bolt-circle diameter, and are not a direct fit for each other. Do not force the wheel onto the studs. Any proposed conversion needs a compatible, application-approved adapter and a complete fitment check.
What should I check before using a wheel pattern adapter?
Check the specific vehicle and wheel application with the adapter manufacturer and installer. An adapter introduces another mounting interface and changes wheel position. Its thickness, fasteners, installation instructions and clearance requirements matter. There is no universal seasonal-use or terrain-based approval for adapters.
What bolt pattern does the Kawasaki KRX1000 use?
The System 3 catalog example for 2020–2023 KRX models is 4/156, with four lugs. For other years or a modified vehicle, verify the exact application rather than extending the example automatically. The KRX should not be described here as a five-lug 5/114.3 application.
FAQ
What is a 4/137 bolt pattern?
A 4/137 bolt pattern has four lug holes arranged on a circle with a 137 mm diameter. The label describes the mounting pattern, not complete vehicle fitment.
Is 4/137 the same as 4/156?
No. Both have four lugs, but the bolt circles differ by 19 mm. They are not a direct fit for each other.
Can I use a bolt pattern adapter on my UTV?
Only after confirming the specific adapter, vehicle, wheel and installation requirements. Matching the two pattern labels alone does not establish compatibility or clearance.
What bolt pattern does the Kawasaki KRX1000 use?
The System 3 2023 catalog lists 2020–2023 KRX applications at 4/156. Confirm the exact year, trim, current hubs and selected wheel before ordering.
How do I find my UTV's bolt pattern?
Use your exact model year and trim to check vehicle-manufacturer documentation and the wheel maker's application guide. If details are missing or hubs have changed, ask an authorized dealer or qualified installer to verify them.
Will wheel spacers change my bolt pattern?
A same-pattern spacer moves the wheel outward without changing the pattern. A pattern-changing adapter has different hub-side and wheel-side patterns. Read the product specifications rather than relying on its name.
Are 4/136 and 4/137 wheels interchangeable?
Do not assume universal interchangeability. Some wheel manufacturers explicitly list a particular SKU for 4x136/4x137 applications. Get confirmation for the exact wheel and vehicle when the labels differ.
Does bolt pattern affect which tires I can run?
The bolt pattern concerns the wheel-to-hub connection. Tire fitment also requires the correct bead-seat diameter, an approved rim width, suitable load capacity and adequate vehicle clearance.
One last thing
Before checkout, confirm the whole combination: exact vehicle, current hubs, selected wheel SKU, bore and hardware requirements, offset, intended tires and clearance. If any of those are uncertain, ask R1 or your installer to resolve them before mounting the tires.
