RockTrix 4x4 Wheel Spacers 1in Thick for Golf Carts - Improved

In this review the RockTrix 4x4 Wheel Spacers prove to be a practical upgrade for golf cart and small ATV owners who need extra clearance or a wider stance. Designed as a set of two 1.0in spacers, they are best for buyers who can confirm their hub centerbore and stud specs first, and who want a sturdy, machined aluminum part that improves stability and appearance without complicated modification. The biggest reason to buy is simple: these spacers reliably add clearance so larger or wider wheels can be fitted while maintaining a clean, aggressive look.

Key Features

• 1.0in thickness: Adds a full inch of clearance so larger or wider rims and tires can be installed without rubbing the fender.
• 4x4" bolt fitment: Matches common 4x101.6 or 4x100 bolt patterns used on many golf carts and small ATVs for straightforward compatibility.
• Precise CNC machining: Manufactured from aerospace billet aluminum for tight tolerances that reduce wobble and improve fit.
• Anodized finish: Provides corrosion resistance and a clean silver appearance that enhances the cart's stance and look.
• Included heat-treated studs: Uses 10.9 grade carbon steel studs and nuts for secure fastening and reduced risk of thread damage.
• Clear install guidance: Supplied specs and safety advice help installers torque correctly and re-check hardware after initial miles.

Who It's For

These spacers are for golf cart and small ATV owners who want to fit wider or larger wheels for improved stability, a more aggressive stance, or to clear larger tires. They work well for models with a 4x101.6 or 4x100 bolt pattern and for owners capable of verifying hub centerbore and stud thread size before purchase.

Not every buyer is a fit: do not buy without confirming your vehicle centerbore is no larger than 61.25mm, your wheel studs and lug nuts are 1/2-20 thread, and you have at least 1.0in of space between fender and tire. If your studs are longer than 1.0in you may need to trim them or seek professional installation.

Pros & Cons

Pros

• Well built from billet aluminum and anodized for corrosion resistance, offering long-term durability.
• Included heat-treated 10.9 grade studs and precise threads reduce the chance of cross-threading during installation.
• Visible improvement in stance and handling; customers report better stability on slopes and an aggressive look.

Cons

• Requires verification of centerbore and stud specs before purchase, and overly long studs may need trimming to fit.
• Installation requires basic tools and torqueing; first-time installers may prefer professional help.
