KAX 5x4.5 Wheel Spacers 20mm 5 Lug Hub Centric - Improved Track & Fit

In this review the KAX 5x4.5 wheel spacers are evaluated for drivers who need a modest track widening and a reliable hub centric fit. These 20mm, bolt on spacers are aimed at owners of many 5x4.5 bolt pattern vehicles such as Hyundai, Mazda, Mitsubishi and certain SUVs who want improved stance, corrected offset for aftermarket wheels, or extra clearance for larger tires. The single biggest reason to buy is the secure hub centric design forged from 6061-T6 aluminum paired with SGS certified 10.9 grade bolts, which together deliver a purposeful upgrade that keeps wheels centered and more stable under driving loads.

Key Features

• 20mm thickness: Adds a safe, modest increase in track width to improve handling and create clearance for wider tires or aftermarket wheels.
• Hub centric 67.1mm bore: The raised center lip matches the hub bore to reduce vibration and ensure a snug, concentric fit.
• M12x1.5 studs and nuts: Comes with threaded M12x1.5 studs and 10.9 class split nuts for high strength fastening and consistent torque retention.
• 6061-T6 forged aluminum: Forged from aircraft quality alloy for a balance of light weight and structural strength under road conditions.
• Wide vehicle compatibility: Listed for many 5x4.5 vehicles including Elantra, Sonata, CX-5, Optima and others, so buyers with common platforms will find these fit options useful.
• Installation kit and manual: Package includes four spacers, 10.9 class split nuts and an instruction manual to assist bolt on installation.

Who It's For

These spacers suit drivers who want a modest, bolt on increase to track width to fix clearance or offset issues when fitting aftermarket wheels, or who want a slightly wider stance for improved cornering stability. Owners of compatible cars listed by maker and model will find the hub centric lip and included hardware convenient for a shop or competent DIY installer.

They are not for drivers who need very large offsets, custom stud patterns, or those unwilling to verify stud length and fender clearance. Anyone without at least 2 in of space between the tire and fender or with very short factory studs should consult a professional or choose a spacer thickness that matches their studs.
