Many off-roading enthusiasts use Land Rover Defender wheel spacers to fit wider AT tires, improve stability on challenging terrains, and achieve a more aggressive look. But the big question is: What types of wheel spacers are the best? Let’s dive in to help you avoid costly mistakes.

Defender Wheel Spacers: Bolt-on vs Slip-on

There are different Defender spacers: bolt-on types and slip-on types. The bolt-on spacers are bolted to the vehicle studs and following the wheels are secured on the spacers with the provided lug nuts. They are perfect for Land Rover Defender that use lug nuts to lock the wheels.

On the other hand, slip-on spacers simply slide over your existing wheel studs. If you need around 3mm to 12mm wheel spacers, slip-on wheel spacers will do. This type of wheel spacer doesn’t come with pressed-in wheel studs. You need new longer wheel studs to safely secure the spacers and wheels.

Pro Tips: The Defender bolt-on wheel spacers are a better choice for rock crawling since they are less likely to come loose.

Defender Wheel Spacers: Hub-centric vs Lug-centric

Defender hub-centric wheel spacers are designed with center rings that fit perfectly the axle and the space inside the center bore of the wheel. This ensures the wheel is properly centered on the spacer, reducing vibrations and preventing potential safety issues.

Defender lug-centric wheel spacers come with larger hub bore diameters so that the spacer can fit a wider array of vehicles. Without the support of the hub (because of the gap), the wheel cannot be centered on the axle, leading to annoying wheel vibrations while driving.

Pro Tips: The Defender hub-centric wheel spacers are a better choice for rock crawling since they provide even load distribution and minimize vibration.

1. Active Cooling for Better Braking Performance

To further improve the heat dissipating ability, BONOSS forged Defender wheel spacers come with petal-shaped cooling grooves. These grooves allow the external cold air to flow continuously inside the wheel spacer when it rotates. The air takes away the heat, so these BONOSS forged active cooling Defender wheel spacers can actively dissipate heat for the braking system.

2. Forged Aluminum for Improved Safety

If you are looking for wheel spacers with durability and lightweight, then buying aluminum wheel spacers for a Land Rover Defender is the route to go. After a super forging process, the tensile strength of BONOSS forged 7075-T6 aluminum wheel spacers is up to 572 MPa. The higher the tensile strength, the more tensile stress that the wheel spacers can withstand before failure.

3. Full-cone Seat for Enhanced Stability

When it comes to Defender bolt-on spacers, there are lug holes. BONOSS forged active cooling wheel spacers come with precise full-cone lug seats. The full-cone shape allow the wheel nuts to fully contact the spacers, providing a stronger and more secure fit. This is effective to avoid any potential loosening risks.
