RockTrix 4x4 Wheel Spacers 1.5 in Thick - Improved Clearance & Stance

In this review of the RockTrix 4x4 Wheel Spacers the bottom line is simple: these spacers are for owners who want a reliable, CNC-machined way to increase clearance and give a golf cart or small ATV a wider, more aggressive stance. Installers will appreciate that the kit includes two 1.5 in spacers with heat-treated studs and anodized billet aluminum construction, and the single biggest reason to buy is the combination of precise fitment for 4x4 in bolt patterns and solid build quality that customers repeatedly praise.

Key Features

• Thickness: 1.5 in wide spacer provides consistent extra clearance to fit larger or wider rims and tires without rubbing the fender.
• Bolt pattern: 4x4 in (4x101.6 or 4x100) compatibility makes these usable on many golf carts and ATVs that use that standard bolt layout.
• Material: CNC machined from aerospace billet aluminum and anodized to resist surface corrosion and maintain appearance under outdoor use.
• Studs: Includes heat-treated 10.9 grade carbon steel studs with precise threads to reduce the chance of cross-threading during installation.
• Fitment checks: The design requires buyers to verify centerbore, stud length and 1/2-20 thread size, helping ensure a safe, correct installation.
• Stability benefit: By widening track width the spacers can improve handling and stability, a benefit noted by customers on slopes and uneven ground.

Who It's For

These spacers suit owners of EZ GO, EZGO, Club Car and similar golf carts and small ATVs that share a 4x4 in bolt pattern and use 1/2-20 studs. They are a good fit for people who want a simple mechanical way to run wider wheels, improve stance, or gain a modest handling advantage without changing suspension components.

They are not for buyers who cannot confirm the vehicle centerbore is no larger than 61.25mm, who have wheel studs longer than 1.5 in and cannot trim them, or who lack the basic tools to torque lug nuts to manufacturer specs. Novices should consider professional installation if they are unsure about stud length or torque procedure.

Pros & Cons

Pros

• Well-made CNC billet aluminum construction gives durable corrosion resistance and a clean appearance.
• Included heat-treated studs and precise threads simplify installation and reduce cross-thread risk.
• Effectively increases clearance and improves stance and stability as reported by several customers.
• Good value for money relative to the quality and the included hardware.

Cons

• Requires verification of centerbore, stud thread size and stud length; long studs may need grinding to fit.
• Professional installation recommended for first-time installers, which adds cost for some buyers.

Frequently Asked Questions

Will these fit my cart?
They fit carts with a 4x4 in bolt pattern and 1/2-20 studs, provided the vehicle centerbore is no larger than 61.25mm and there is 1.5 in of clearance between fender and tire.

Do I need new studs?
The kit includes heat-treated studs; however if your current wheel studs are longer than 1.5 in you may need to trim them or replace them to ensure proper fit.

Is professional installation required?
Installation is straightforward with common tools and a torque wrench, but professional installation is recommended for first-time installers to ensure correct torque and safety checks.
