Wheel Accessories Parts ATV UTV Wheel Spacers 2-Pack 4x156mm 1.00 in Black CNC 6061-T6

If you need to widen your ATV or UTV track, clear brake calipers, or fit wider tires without changing hubs, these wheel spacers deliver a factory-spec solution. Machined from forged 6061-T6 aluminum and anodized black, the pair is built to resist corrosion and reduce the chance of vibration. They come pre-drilled for a 4 on 156mm (4x156mm) bolt pattern, accept a 130mm hub diameter, and use 3/8" thread studs rated SAE 10.9 for secure lug engagement.

Will these spacers fit my Polaris model?

They are engineered to match vehicles that use a 4 on 156mm (4x156mm) bolt pattern with a 130mm hub diameter. The fit is specific, so verify your vehicle’s bolt pattern and hub OD before ordering.

• Bolt pattern: 4 on 156mm (4x156mm)
• Hub/ID: 130mm wheel ID and 130mm vehicle hub OD
• Thread size: 3/8" studs (SAE 10.9)
• Known Polaris fitments include classic and later models like Ranger, RZR, Sportsman, Scrambler, Big Boss and Brutus

How do these spacers change handling and clearance?

Adding a 1.00-inch spacer increases track width and moves wheels outward, which can improve lateral stability and reduce body roll in turns. They also create extra clearance between the wheel and suspension components, helping with brake caliper interference and allowing wider tire options.

• Increases track width by 1.00 inch per side when installed on both sides
• Raises tire-to-caliper and tire-to-swingarm clearance
• Enables fitment of wider or higher-traction tires without hub replacement
• Helps achieve a more aggressive stance for trail and utility use

What materials and manufacturing processes ensure durability?

These spacers are forged from 6061-T6 aluminum, then CNC-machined to tight tolerances for concentricity and fit. Anodized black for corrosion resistance, the design aims to minimize runout and vibration while providing long-term strength under load.

• Forged 6061-T6 aluminum stock for improved strength-to-weight
• CNC lathe and milling finish for accurate bolt pattern and hub bore
• Anodized black surface for corrosion protection
• Included studs rated SAE 10.9 for secure fastening

How straightforward is installation?

Installation is intended to be simple and fast for anyone familiar with wheel removal. The spacers slide onto the vehicle hub and accept your wheel—no cutting or welding is required—though torque specs and safety checks should be followed.

• Designed for bolt-on installation with standard hand tools
• No special hub modifications required when matched to your vehicle specs
• Install both sides for balanced track width changes
• Always torque to manufacturer or spacer-specified values and recheck after a short break-in ride

Who is this for: ATV and UTV owners who need a reliable, factory-spec spacer to widen track width, clear brake or suspension interference, or fit larger tires without replacing hubs. Best suited for Polaris models that match the 4x156mm bolt pattern and 130mm hub diameter, and for riders who prefer a bolt-on upgrade that combines strength, precision machining, and corrosion resistance.
