4x110 Wheel Spacers 1.5in 38mm with 101.25 Studs - ATV Fitment

In this review the GAsupply 1.5 4x110 wheel spacers are evaluated for riders who need extra clearance and a wider stance on small ATVs and similar machines. The bottom line: these 38mm spacers deliver a straightforward way to run wider or taller tires and improve stability, provided your hub bore is 74mm or smaller and your wheels use M10x1.25 studs. They are best for owners who want a durable, lightweight spacer that installs with existing lug hardware and gives an immediate visual and handling benefit.

Key Features

• Fitment: Designed for vehicles with a 4x110 bolt pattern and M10x1.25 studs, ensuring a snug, bolt-on fit for compatible ATVs.
• Thickness: The 38mm (1.5in) thickness increases tire clearance and allows installation of wider or higher-traction tires without major suspension changes.
• Material: CNC machined from 6061-T6 aluminum billet to stay strong while minimizing added unsprung weight for preserved handling.
• Hardware: Pre-installed 12.9 grade bolts provide high strength fastening and reduce the need to source separate studs.
• Finish: Anodized surface adds corrosion resistance so the spacers resist rust and cosmetic fading from outdoor use.
• Hub Bore: 74mm maximum center bore keeps the spacer centered on common ATV hubs for predictable fitment.

Who It's For

This product suits ATV owners who have a 4x110 bolt pattern and M10x1.25 wheel studs and who want to run wider or taller tires, or simply widen the track for improved turning stability. It is also a good match for riders seeking a lightweight, corrosion-resistant spacer made from billet aluminum rather than cast components.

Owners whose wheels use different stud sizes (for example 12x1.25) or vehicles with a hub bore larger than 74mm should look elsewhere. Also, riders who need integrated wheel centric rings or spacer designs specifically matched to unique hub offsets may require a different product.

Pros & Cons

Pros

• Solid build quality from 6061-T6 aluminum delivers strength with low weight as reported by customers praising build quality and stability.
• Easy installation for compatible machines, with factory lug nuts threading on in user reports and straightforward bolt-on fitment.
• Improves handling and clearance, giving a noticeably more aggressive stance and better turning stability for younger or lighter riders.
• Corrosion-resistant anodized finish helps the spacers retain appearance and resist rust over time.

Cons

• Limited to wheels with M10x1.25 studs and a hub bore no larger than 74mm, so it will not fit vehicles with 12x1.25 studs or larger bores.
• Fit depends on exact model year and wheel centering; customers should verify fitment before purchase.

Frequently Asked Questions

Will these fit my ATV with 12x1.25 studs?
No. These spacers only fit wheels with M10x1.25 studs and will not work with 12x1.25 studs.

Do I need special lug nuts?
In most cases no; customers report factory lug nuts thread on easily for compatible applications, but verify nut seat type and length for your wheels.

What if my hub bore is larger than 74mm?
These spacers require a hub bore no larger than 74mm to center properly; a larger bore will need adapter rings or a different spacer sized for that hub.
