ATV Wheel Spacers 4x110 1.5in 38mm - Improve Clearance & Stability

In this review the ATV Wheel Spacers 4x110 are evaluated for riders who need extra tire clearance and improved handling on compatible ATVs. The biggest reason to consider these spacers is their combination of lightweight CNC machined 6061-T6 aluminum construction and pre-installed grade 12.9 bolts, which deliver strength without much added weight. They are a practical upgrade for machines with a 4/110 bolt pattern, a center bore no larger than 74mm, and M12x1.25 studs, offering a straightforward way to widen track width and fit wider or higher-traction tires.

Key Features

• Fitment: Designed specifically for vehicles with a 4/110 bolt pattern and M12x1.25 studs, ensuring correct mounting when match criteria are met.
• Material: CNC machined from 6061-T6 aluminum billet to provide a strong but lightweight spacer that does not overly burden unsprung weight.
• Hardware: Pre-installed grade 12.9 bolts mean users get high-strength fasteners ready for installation without sourcing extra studs.
• Thickness: At 38mm (1.5in) thickness the spacer increases track width enough to improve stability and allow wider tires to clear the bodywork.
• Finish: Anodized chrome surface gives corrosion resistance so the spacer resists rust and fading in outdoor use.
• Simplicity: Sold as a 2 pack for axle pairs, which simplifies upgrading both sides with consistent spacing and fit.

Who It's For

This product is best for ATV owners who need to fit larger or higher-traction tires, or who want a wider stance for improved cornering stability, particularly on models known to use a 4/110 bolt pattern such as several small-displacement utility and youth ATVs. Riders who value a durable, light alloy spacer with good corrosion resistance will appreciate the CNC construction and anodized finish.

Not every ATV owner should buy these: do not purchase unless your hub bore is 74mm or smaller and your wheel studs are M12x1.25. If your studs are 10x1.25 or your bolt pattern differs, look for spacers specified for those dimensions instead.

Pros & Cons

Pros

• Well built from 6061-T6 aluminum and feels solid when bolted to stock hubs, delivering real improvements in stability.
• Easy to install with pre-installed grade 12.9 bolts, reducing installation time and parts sourcing.
• Chrome anodized finish offers good corrosion resistance for outdoor and off-road conditions.

Cons

• Only fits wheels and hubs that meet the 4/110, 74mm hub bore, and M12x1.25 stud specifications, so compatibility is limited.

Our Verdict

These ATV wheel spacers are a sensible, value-minded upgrade for riders with compatible hubs who want to increase tire clearance and improve stability.
