The Jeep Gladiator wheel spacers are used to push the wheels and tires out a few distances. This creates more inner wheel clearance to avoid any wired tire wear. Whether you are upsizing the wheels, installing bigger brake calipers, or simply widening your truck’s track, wheel spacers turn out to be the most cost-effective way to solve fitment issues.
There are steel and aluminum alloy wheel spacers available in the market. As many engineer claims, forged wheel spacers are generally better for off-roading upgrades. Always choose the right wheel spacers, and you will have safe and enjoyable driving. But the big question is: What types of Jeep Gladiator wheel spacers are the best? Let’s dive in to help you avoid costly mistakes.

Jeep Gladiator Wheel Spacers: Steel vs Aluminum
Technically, steel wheel spacers are hard and strong. The high concentration of carbon contributes to its overall hardness but also makes its weight heavier. Besides, some low-quality steel spacers can quickly corrode. Experts will choose aluminum spacers.
On the other hand, Jeep Gladiator aluminum wheel spacers are lightweight and strong, meaning they won’t add much weight. What’s better, due to the material properties, these aluminum spacers are good in corrosion resistance and rust-proof.
Top Picks of Jeep Gladiator Aluminum Wheel Spacers
The 6061-T6 and 7075-T6 aluminum alloys are two popular materials for manufacturing high-strength Jeep Gladiator wheel spacers. But which type is the best? Let’s have a look at what experts pick:
- Daily Drivers: For those who mainly drive on streets or light off-road, the 6061-T6 wheel spacers are just enough. They can withstand certain impacts without cracking.
- Off-Road Enthusiasts: For those who frequently hit the trails, forged 7075-T6 spacers are the best option. The 7075-T6 aluminum spacers are less likely to break even under hard driving. Experts recommend forged 7075-T6 spacers for off-roading use.

Who Sells the Best Jeep Gladiator Wheel Spacers Nearby?
BONOSS produces Jeep Gladiator wheel spacers (1-inch to 3-inch) and has developed special wheel spacers for various off-roading adventures. Safety, precision, strength, and best experience are what sets BONOSS apart from other spacer manufacturers. BONOSS offers several key advantages that make their spacers a top choice.
1. Active Cooling for More Adventures
BONOSS forged active cooling Jeep Gladiator wheel spacers improve brake cooling efficiency. The heat dissipation grooves send the external cold air to flow continuously inside the wheel spacer when it rotates. The air takes away the heat, so it achieves the purpose of actively dissipating heat for the braking system. It would be better if the spacers could solve the rubbing problem and provide more functions.
2. Aerospace-grade Aluminum, Zero Damage
For the ultimate performance, BONOSS forged active cooling Jeep Gladiator wheel spacers are made of billet aluminum 6061-T6 or even a special 7075-T6 aluminum, these aircraft quality alloys are forged with up to 3000 tons of pressure. The ultimate tensile strength results of these two aluminum alloys are:
- Forged 6061-T6 spacers: 42000-45000 psi (300-310 MPa);
- Forged 7075-T6 spacers: 74000-78000 psi (510-572 MPa).
Such BONOSS forged active cooling Jeep Gladiator wheel spacers won’t break even under hard driving.
3. Strong Fasteners for Zero Loosen
To safely secure the spacers, BONOSS provides ISO grade 12.9 wheel studs (tensile strength≥1,220 MPa) and ISO grade 10 wheel nuts (proof load≥1,110 MPa). They are meticulously coated with Dacromet. This type of coating gives neutral salt spray resistances exceeding 500 hours. They won’t loosen easily in off-roading conditions.
4. Precisely Machined for No Deviation
These BONOSS forged active cooling Jeep Gladiator wheel spacers are CNC machined, precision at 0.02mm tolerance. The smaller the tolerance value, the higher the accuracy, the better the surface quality, and the higher the reliability. The wheels are well-balanced so that there will be less chance of vibrations.
Final Verdict: Elevate Your Wheel Style with BONOSS
With those outstanding advantages, it’s clear that BONOSS forged active cooling Jeep Gladiator wheel spacers offer exceptional safety, durability, and professionalism. With the right wheel spacers, your vehicle can look even more impressive and perform even better on or off the road. Your vehicle deserves the best. Happy modding!
