In this review the KAX 4x4 wheel spacers 1 in are presented as a practical upgrade for owners of compatible off-road and utility vehicles who need extra track width or clearance. The biggest reason to buy is simple: these bolt on spacers are forged from aircraft quality 6061-T6 aluminum and come with SGS certified 10.9 grade split nuts, giving a combination of light weight and strong fastening that reviewers repeatedly cite as reliable. They are best suited for riders who value precise fit and straightforward installation for specific 4x4 applications.

Key Features

• 1 in Thickness: Provides a consistent increase in track width to improve stability and help resolve offset or clearance issues with aftermarket wheels.
• 6061-T6 Forged Construction: Forging from aircraft quality aluminum delivers a durable, lightweight spacer that resists deformation under normal driving conditions.
• 59mm Center Bore: The lug centric 59mm bore centers the spacer on the hub for accurate fitment when the vehicle and wheel bolt pattern match 4x4.
• 1/2"x20 Studs and Nuts: Includes threaded studs and SGS certified 10.9 class split nuts to ensure secure attachment and consistent torque retention.
• Complete Kit: Package contains two spacers, the required split nuts and a professional instruction manual to simplify installation.
• Recommended Torque: Clear torque guidance of 75-85 ft/lbs helps ensure safe, repeatable installation and long term reliability.

Who It's For

The KAX 1 in wheel spacers are aimed at owners of the listed Trail Boss, Trail Blazer, Xpedition and similar models who need a bolt on, lug centric spacer to correct clearance or offset problems or to widen the stance for off-road stability. They appeal to mechanically confident owners who can verify hub bore, bolt pattern and wheel stud length before fitting.

Buyers who should look elsewhere include those with incompatible bolt patterns, less than 2 in of fender-to-tire clearance, or who cannot trim long factory studs when needed; also anyone expecting a universal fit should confirm vehicle compatibility carefully before purchase.
