KAX 5x4.5 Wheel Spacers 1 in Thick - Hub Centric Bolt On Fit

In this review the KAX 5x4.5 wheel spacers are evaluated for drivers who need a reliable, bolt on solution to clearance and offset issues. The bottom line: these 1 in (25 mm) thick, hub centric spacers are best for owners of compatible Toyota and Lexus models who want a precise fit and stronger stance without complicated installation. They are forged from 6061-T6 aircraft grade aluminum and include SGS certified 10.9 class split nuts, so the primary reason to buy is durability combined with straightforward bolt on installation.

Key Features

• Material and construction: Forged 6061-T6 aluminum provides high strength and corrosion resistance for long service life.
• Fitment: The 5x4.5 bolt pattern and 60.1 mm center bore with lip deliver a hub centric fit for compatible Camry, RAV4, Highlander and Lexus models.
• Thickness: The 1 in (25 mm) spacer width widens the track to correct offset and clearance issues with aftermarket wheels.
• Hardware included: Each kit includes four spacers plus 10.9 class split nuts and an instruction manual so installers have the necessary fasteners.
• Recommended torque: Designed to be tightened to 70-80 ft/lbs for a secure, repeatable clamping force when installed correctly.

Who It's For

The KAX spacers are aimed at owners of vehicles with a 5x4.5 in (5x114.3 mm) bolt pattern who need an easy, bolt on spacer to correct wheel offset or to improve stance and wheel clearance. They suit drivers fitting wider or different offset wheels on Camry, RAV4, Highlander, Sienna, RX350/450h, ES350/330, Venza, Avalon and Prius V models listed as compatible.

Those who should look elsewhere include drivers with nonlisted bolt patterns or insufficient fender-to-tire clearance under 2 in, and anyone unwilling to check stud length or perform the modest mechanical steps required for safe installation and torque checks. Professional installation is recommended if you are not comfortable with wheel torque specifications.

Pros & Cons

Pros

• Solid forged 6061-T6 construction gives a durable, lightweight spacer that resists deformation.
• Hub centric 60.1 mm bore with a lip helps maintain wheel alignment and reduces vibration risk when correct fitment is used.
• Includes SGS certified 10.9 split nuts and instructions, simplifying bolt on installation for most users.
• One inch thickness addresses clearance and offset issues without radical modification to the vehicle.

Cons

• Some users reported surface scratches during installation, so careful handling and protective measures are advised.
• Not suitable if you have less than 2 in of space between fender and tire or if stud trimming would be required and you are not prepared to modify studs.

Our Verdict

Frequently Asked Questions

Will these spacers cause vibration?
When matched to the correct 5x4.5 bolt pattern and the 60.1 mm hub bore they are hub centric and should not cause vibration; proper torque and wheel mounting are required.

Do I need to trim my wheel studs?
Only if your factory studs are longer than needed; the guide notes trimming may be necessary when studs extend more than is safe after spacer installation.

Are nuts and instructions included?
Yes, the kit includes 10.9 class split nuts and a professional instruction manual for installation guidance.
