RockTrix 4x4 Wheel Spacers 2 in Thick - Extra Clearance & Stance

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 for wider rims or oversized tires. The set of two 2.0 in spacers is designed specifically for 4x4 in bolt patterns and comes with M12x1.25 studs and nuts; the single biggest reason to buy is that they reliably increase track width and stance while being CNC machined from aerospace billet aluminum, which customers repeatedly praise for fit and finish.

Key Features

• Thickness 2.0 in: Provides 50mm of additional clearance so larger or wider rims and tires can be fitted without rubbing the fender.
• Bolt Pattern Compatibility: Works with 4x4 in (4x101.6) and 4x100 bolt patterns to fit many golf carts and ATVs using those patterns.
• Hub Bore 68.5mm: A defined center bore that centers the spacer on the hub for consistent wheel alignment and reduced vibration.
• M12x1.25 Studs/Nuts: Includes heat treated 10.9 grade studs that thread precisely to avoid cross threading during installation.
• CNC Machined Aluminum: Aerospace billet construction and anodized finish resist corrosion and provide a clean, factory-quality appearance.

Who It's For

These spacers are best for golf cart and small ATV owners who already run 4x4 in or 4x100/4x101.6 bolt pattern wheels and want to fit wider rims or oversized tires, or to create a wider, more aggressive stance for improved stability. They suit DIYers comfortable using basic tire tools and a torque wrench, and reviewers noted easy installation when vehicle studs and clearances match.

Owners should verify their vehicle centerbore is not larger than 68.5mm, wheel stud thread is M12x1.25, and there is at least 2.0 in (50mm) of space between the fender and wheel. If a buyer cannot confirm those points or lacks a torque wrench, professional installation is recommended and they should look elsewhere until measurements match.

Pros & Cons

Pros

• Nicely machined aluminum finish improves wheel aesthetics and resists corrosion.
• Increases stability and stance, helping fit larger tires without rubbing.
• Included 10.9 grade studs and precise threads reduce risk of cross threading during fitment.
• Relatively straightforward installation for those with basic tire tools.

Cons

• Requires verification of hub bore, thread size, and minimum 2.0 in clearance before purchase, which adds a measurement step.
• If vehicle wheel studs are longer than 2.0 in, studs may need trimming or replacement to fit.

Frequently Asked Questions

Will these fit my golf cart?
They fit carts with a 4x4 in (4x101.6 or 4x100) bolt pattern, a centerbore no larger than 68.5mm, M12x1.25 wheel studs, and at least 2.0 in of fender-to-wheel clearance.

Do I need special tools to install?
Standard tire tools, a torque wrench, and a lug socket are required; professional installation is recommended if you are unsure.

What if my wheel studs are too long?
If studs exceed 2.0 in they may need to be ground or replaced to fit properly; consult a technician if unsure.
