ATV Wheel Spacers 3/8ft-24 Studs 1.5 in 4 Lug Spacer Adapters

In this review of the ATV Wheel Spacers 3/8'-24 Studs 1.5 in, the bottom line is simple: these spacers are for riders who need extra tire clearance and a wider track without replacing hubs or wheels. The reviewer found the set most useful for quads with a 4/156 bolt pattern and a center bore no larger than 131mm, where the CNC-machined 6061-T6 aluminum and pre-installed 12.9 grade bolts deliver a sturdy, lightweight upgrade. Fitment must be verified beforehand, but when matched correctly the spacers quickly improve stance and allow room for larger, high-traction tires.

Key Features

• Precision machining: CNC machined from 6061-T6 aluminum for a consistent, lightweight spacer that resists deformation under load.
• Corrosion resistance: Anodized surface reduces rust and fading for longer life in wet and muddy conditions.
• Secure hardware: Pre-installed 12.9 grade bolts provide strong clamping force and reduce chances of fastener failure over time.
• Fitment specifics: Designed for vehicles with a 4/156 bolt pattern, 131mm or smaller center bore, and 3/8-24 studs to ensure correct fit when matched.
• Increased clearance: The 38mm (1.5 in) thickness gives added room for wider or taller tires to improve traction and handling in off-road situations.

Who It's For

This product suits ATV and quad owners who know their bolt pattern and stud thread size and want a reliable spacer to widen track width or fit larger tires without expensive hub replacements. It is especially useful for riders seeking a more aggressive stance and improved tire clearance for trail or utility use.

Those who should look elsewhere include owners whose vehicle bolt pattern is not 4/156, who have a center bore larger than 131mm, or who use 12x1.5 studs; improper fit will prevent safe installation. Riders uncomfortable measuring bolt pattern, hub bore, or thread pitch should consult a mechanic before purchasing.

Pros & Cons

Pros

• Solid build quality from 6061-T6 aluminum gives a good strength-to-weight ratio.
• Anodized finish adds corrosion resistance for longer service life in harsh conditions.
• Pre-installed 12.9 grade bolts and clear instructions make installation straightforward for a DIYer.
• Measured 38mm thickness reliably increases tire clearance without major modifications.

Cons

• Only fits vehicles with a 4/156 bolt pattern and 3/8-24 studs, so many ATVs will be incompatible.
• Some customers reported mixed functionality on certain models, so fit verification is essential before ordering.

Specifications

Our Verdict
