RokBlokz Wheel Spacers: Engineering the balance of Safety, Fitment, and Performance

At RokBlokz, we’re committed to providing the best gear for your ride, and our aircraft-grade 7075 T6 aluminum hub centric wheel spacers are no exception. Whether you're after better wheel fitment, clearing big brake kits, or just perfecting your car’s stance, our wheel spacers are engineered for maximum performance and safety.

What Are Wheel Spacers, and Why Do You Need Them?

Wheel spacers are machined discs designed to fit between your wheel and brake rotor. They help adjust your wheel's offset, moving the wheel outward from the hub. But why does this matter?

Your wheel's offset determines how far in or out it sits relative to your car’s body. A higher offset tucks the wheels closer to the car, while a lower (more aggressive) offset pushes them outward. Depending on your wheel and tire setup, aftermarket suspension, or big brake kits, you may need to adjust this offset to achieve proper clearance and fitment.

That’s where RokBlokz Wheel Spacers come in. If you’ve upgraded your brakes, suspension, or simply want a wider stance, spacers give you the flexibility to dial in the exact fitment you want—without the hassle of buying new wheels.

Are Wheel Spacers Safe to Use?

The short answer? Yes—if they’re installed correctly and built with high-quality materials.

At RokBlokz, we prioritize both safety and performance. Our bolt-on wheel spacers are crafted from aircraft grade 7075 T6 aluminum, a top-tier material known for its exceptional strength. Compared to the more common 6061-T6, 7075 T6 aluminum offers superior durability and stress resistance, which is crucial for maintaining safety at high speeds and under tough driving conditions. This material is lightweight but incredibly strong, allowing your vehicle to handle greater loads without compromising its performance or structural integrity.

But the material isn’t the only thing that sets our spacers apart. Every RokBlokz wheel spacer is hub-centric, meaning they’re designed to perfectly match the hub of your vehicle. This ensures that the weight of the vehicle is evenly distributed, reducing the risk of dangerous vibrations that can occur with poorly fitted, lug-centric spacers. The hub-centric design maintains your car’s alignment, keeping the ride smooth and safe—especially at higher speeds or during intense driving maneuvers. Proper fitment isn’t just a matter of comfort, it’s a key factor in your vehicle’s overall safety and performance.

When Should You Use Hub Centric Wheel Spacers?

There are several key reasons why you’d want to install hub centric wheel spacers on your vehicle:

1. Clearance for Big Brakes
   If you’ve upgraded to a larger brake kit, chances are your stock or aftermarket wheels don’t have the clearance to fit around the calipers. A spacer will push the wheel out just enough to avoid rubbing while keeping your braking performance sharp.
2. Clearance for Aftermarket Suspension
   Aftermarket control arms, coil-overs, or other suspension upgrades might require more room for everything to function without interference. Wheel spacers ensure that your wheels won’t rub on suspension components, especially during hard turns or when the suspension is fully compressed.
3. A More Aggressive Stance
   Sometimes, you just want your ride to look tough. By pushing the wheels out a bit, spacers give your car that wide, aggressive stance—filling up the wheel wells and giving it a more planted look. It’s not just about aesthetics, though. A wider stance can also improve stability by giving the car a wider track.
4. Perfect Wheel Fitment Without New Wheels
   Finding the right wheels can be a challenge, especially if you're dealing with unique offsets or hard-to-find sizes. Rather than spending big bucks on a new set of wheels, spacers allow you to fine-tune the fitment of your existing wheels to match your exact needs.

Wheel Spacer Thickness: How to Get It Right

The thickness of your spacer depends on your fitment needs. The basic principle is simple: a 5 mm spacer moves the wheel out by 5 mm, a 20 mm spacer moves it out 20 mm, and so on. But how do you know what size you need?

Start by measuring the distance from the outer edge of your tire to the inside of your fender. You want enough room to push the wheels outward without causing the tires to rub, especially when turning or going over bumps. Too thick, and you risk tire damage and handling issues; too thin, and you may not get the clearance you need for those bigger brake calipers or aftermarket suspension.

Our RokBlokz wheel spacers are available in various sizes to match different setups, ensuring you get the perfect fitment for your ride. For example, a 15 mm spacer might be ideal for clearing brake calipers, while a 25 mm spacer could be perfect for achieving that wider stance you’ve been dreaming of.

How to Install Bolt-On Wheel Spacers

Installing RokBlokz bolt-on wheel spacers is straightforward, but precision is key. Here’s how to get it done:

1. Lift the Vehicle
   Start by jacking up your car and supporting it securely on jack stands. Safety first! Make sure the vehicle is stable before removing any wheels.
2. Clean the Hub
   Before mounting your new spacer, clean off any rust or corrosion from the hub and brake rotor. This ensures a smooth, flat surface for the spacer to sit on, preventing any issues down the road.
3. Apply Anti-Seize
   To make future removal easier, apply a dab of anti-seize lubricant to the hub and the mating surface of the spacer. This helps protect against corrosion and makes disassembly a breeze.
4. Mount the Spacer
   Slide the spacer onto the hub, ensuring a snug fit. Using the included hardware, fasten the spacer to the hub by tightening the nuts. Use a torque wrench to ensure each nut is tightened to your vehicle's factory specs.
5. Install the Wheel
   Now, mount your wheel onto the spacer, tightening the lug nuts to the correct torque specs. It’s essential to follow your car’s recommended torque settings to keep everything secure.
6. Double-Check Everything
   After lowering the car back to the ground, recheck the torque on all your lug nuts after driving a few miles. This ensures everything has settled properly.

Why Quality Matters

Let’s be real—cutting corners when it comes to your wheels and spacers is a bad idea. Cheap spacers can crack, corrode, or even fail under stress, which is why RokBlokz wheel spacers are built from aircraft-grade 7075 T6 aluminum, designed to endure the toughest conditions. We know that enthusiasts like you put your vehicles through more than the average driver, so we’ve made sure our spacers can handle the pressure, whether you’re carving corners on the track or tearing it up off-road.

Additionally, our spacers are hard anodized to prevent corrosion and extend their lifespan. If you've ever had wheels fuse to the hub after a harsh winter, you'll appreciate how anodizing helps keep everything easy to remove and looking good over time.
