ATV Wheel Spacers 4x110 1.5in Adapters - Improved Clearance

In this review the ATV Wheel Spacers 4x110 are evaluated for riders who need extra tire clearance and a wider stance. The bottom line: these 1.5in spacer adapters are best for ATVs with a 4/110 bolt pattern and M10x1.25 studs and deliver a straightforward way to fit wider or higher-traction tires while improving stability. The reviewer found they are CNC machined from 6061-T6 aluminum with quality 12.9 grade bolts and an anodized finish that resists corrosion, making them a practical upgrade rather than an aesthetic-only swap.

Key Features

• Fitment requirement: Designed specifically for vehicles with a 4/110 bolt pattern and M10x1.25 studs, which prevents fitment issues when matched correctly.
• Material and build: CNC machined from 6061-T6 aluminum billet for a strong but lightweight spacer that reduces added unsprung mass.
• Hardware quality: Supplied with pre-installed 12.9 grade bolts so fasteners resist stretching and hold the spacer securely under load.
• Corrosion resistance: Anodized surface treatment helps prevent rust and fading for longer-lasting appearance and function.
• Tire clearance: The 1.5in (38mm) thickness increases track width and allows installation of wider or higher-traction tires for improved handling.
• Quantity and hub bore: Sold as a 2-pack with a 74mm center bore limit to match common ATV hubs when verifying fitment.

Who It's For

These spacers are suitable for ATV owners who need a reliable, machined solution to gain extra clearance or a wider stance on machines that use a 4/110 bolt pattern and 10x1.25mm wheel studs. They work well for hobby riders, parents fitting wider tires for youth machines, and anyone looking to improve turn-in stability or fit larger tires without replacing hubs.

Riders who should look elsewhere include those with a different bolt pattern, a hub bore larger than 74mm, or wheels that require 12x1.25 studs. Also, anyone unwilling to confirm stud thread and hub bore before purchase should choose a spacer listed specifically for their fitment to avoid compatibility problems.

Pros & Cons

Pros

• Well machined 6061-T6 aluminum construction provides strength while keeping weight low.
• Pre-installed 12.9 grade bolts simplify installation and improve long-term reliability.
• Anodized finish offers extra corrosion resistance and keeps the spacers looking good.
• Practical 1.5in thickness meaningfully increases tire clearance and track width.

Cons

• Only compatible with 4/110 bolt pattern and M10x1.25 studs, so fitment must be verified before ordering.
• Center bore must not exceed 74mm, which limits compatibility with some hubs.
