KAX 5x4.5 Wheel Spacers 3 in Hub Centric - Forged 6061-T6 Strength

In this review the KAX 5x4.5 wheel spacers are assessed as a practical bolt-on option for drivers who need a 3 in track widening solution. The bottom line: these spacers are best for owners of compatible Nissan and Infiniti models who want a robust, hub centric spacer machined from forged 6061-T6 aluminum; the single biggest reason to buy is their combination of aerospace-grade construction and SGS-certified 10.9 class nuts that deliver dependable clamping strength without introducing vibration when installed correctly.

Key Features

• Bolt pattern: 5x4.5 (5x114.3mm) compatibility ensures a direct fit to vehicles with that lug layout for straightforward installation.
• Thickness: 3 in (76.2mm) thickness provides substantial track widening to resolve clearance and offset issues with aftermarket wheels.
• Center bore: 66.1mm hub bore with lip makes the spacer hub centric to reduce runout and help maintain low vibration after fitting.
• Material and forging: Forged from aircraft quality 6061-T6 aluminum, the spacer is built for strength while staying relatively lightweight.
• Hardware: Comes with M12x1.25 threaded studs and SGS certified 10.9 class split nuts to give reliable clamping and corrosion resistance under normal driving conditions.
• Torque recommendation: Recommended torque of 70-80 ft/lbs provides a clear installation target to help maintain safe attachment.

Who It's For

The KAX 5x4.5 spacers suit owners of Altima, Rogue, Sentra, Maxima, Murano, Pathfinder, Rogue Sport and QX50 who specifically need a 5x4.5 bolt pattern and a 66.1mm hub bore. They are a good match for drivers fitting aftermarket wheels that create clearance or offset problems or for those seeking a wider track for stability in light off-road or outdoor driving.

Those who should look elsewhere include drivers with a different bolt pattern or hub bore, and anyone who does not have at least 2 in of space between fender and wheel or whose factory studs are too long for a bolt-on spacer without trimming. Professional installation is advised if you are unsure about stud length or fitment.

Pros & Cons

Cons
