KAX 6x5.5 1.5in Wheel Spacers for Tacoma FJ Cruiser 4Runner Tundra

In this review the KAX 6x5.5 wheel spacers earn a recommendation for owners who need a reliable, bolt-on way to correct offset or widen the track on compatible Toyota trucks and SUVs. The single biggest reason to buy is the combination of forged 6061-T6 aluminum construction and SGS certified 10.9 class split nuts, which together deliver a robust, vibration-free fit for those running aftermarket wheels. These spacers are aimed squarely at drivers who need a durable, properly centered spacer with M12x1.5 studs and a 108mm hub bore.

Key Features

• Forged 6061-T6 aluminum: Provides aircraft-quality strength and consistent manufacturing tolerance for long-term durability.
• 1.5 in thickness: Widens vehicle track to correct clearance and offset issues without extreme modification.
• M12x1.5 threaded studs and nuts: Uses common lug thread size and includes high-strength 10.9 class split nuts for secure bolting.
• 108mm center bore, lug centric: Ensures proper centering on 6x5.5 in (6x139.7mm) hubs to reduce vibration risk.
• Recommended torque 70-80 ft/lbs: Clear torque guidance helps installers achieve correct clamp load and safe installation.

Who It's For

The KAX 6x5.5 wheel spacers are best for owners of compatible Toyota models who want a bolt-on solution to push wheels outward for improved stance, clearance, or to accommodate aftermarket wheels. They particularly suit Tacoma, 4Runner, Tundra and FJ Cruiser owners listed in the compatibility notes who have at least 2 in of space between the fender and tire and factory studs shorter than about 2 in.

Those who should look elsewhere include drivers with hubs that do not match a 6x5.5 bolt pattern or a different center bore size, and anyone unwilling to verify stud length or trim studs when necessary; full custom adapters or different thickness spacers may be a better fit for non-standard wheel setups.

Pros & Cons

Cons
