Bora 20mm Steel Wheel Spacers – Precision-Machined for Trucks & SUVs

Installing 20mm spacers on all four corners will increase your vehicle’s overall track width by 40mm (approximately 1.57 inches) — that’s 20mm per side. This widening effect improves stability during cornering and creates a more aggressive stance visually.

The practical impact depends on your current wheel offset and tire size. For most truck applications, this amount of spacing is enough to clear larger tires after a leveling kit, accommodate aftermarket brake calipers, or correct the appearance of wheels with excessive positive offset. It’s a moderate spacing that provides noticeable benefits without pushing the wheels beyond the fender line on stock-width trucks.

No, our 20mm steel wheel spacers come with pre-installed extended wheel studs that are already properly sized and installed. These grade 10.9 hardened steel studs are pressed into the spacer body during manufacturing and provide the correct thread engagement for your wheels.

You’ll use your vehicle’s factory studs to mount the spacer to the hub, then use your original lug nuts to secure your wheel to the spacer’s extended studs. The system is designed so you don’t need to purchase or install any additional hardware — everything required for proper installation is included with your spacer kit.

When properly installed, our 20mm hub-centric steel spacers will not cause vibration or negatively affect ride quality. The hub-centric design maintains the same rotational axis as your factory setup, and our precision machining ensures the spacer runs perfectly true.

Vibration issues with wheel spacers typically result from incorrect installation, mismatched hub bores, or low-quality manufacturing. We machine our spacers to tolerances within 0.001 inches, which eliminates the runout that causes vibration. Thousands of customers run our 20mm spacers daily at highway speeds with zero vibration or balance problems.

We recommend retorquing all fasteners after the first 50 to 100 miles of driving following initial installation. During this break-in period, the spacer assembly will settle as the mounting surfaces mate fully and the fasteners reach their final seated position.

After the initial retorque, check the lug nuts periodically during your regular maintenance schedule — the same way you would with any wheel installation. If you frequently drive off-road or tow heavy loads, inspecting torque values every few thousand miles is good practice. Use a calibrated torque wrench and follow your vehicle manufacturer’s specified torque values for both the spacer-to-hub mounting and the wheel-to-spacer mounting.

For heavy-duty truck and SUV applications, steel spacers offer superior strength and durability compared to aluminum. Our heat-treated carbon steel construction provides a higher load rating and better resistance to impact damage from off-road use or pothole strikes. Steel also handles thermal cycling better — important when spacers are subjected to brake heat and temperature extremes.

Aluminum spacers are lighter and resist corrosion naturally, making them ideal for racing or weight-sensitive builds. However, for trucks that tow, haul payload, or see rugged use, the strength advantage of steel is worth the minimal weight difference. Our 20mm steel spacers are engineered specifically for the demanding conditions that trucks and SUVs encounter during real-world driving.

Yes, our 20mm spacers work with both factory and aftermarket wheels, regardless of offset. Spacers effectively reduce wheel offset by moving the mounting surface outboard — a 20mm spacer decreases offset by 20mm (or increases it by -20mm in offset terminology).

This makes our spacers useful for correcting fitment when aftermarket wheels have too much positive offset and sit too far inboard. Just ensure your aftermarket wheels have a hub bore that matches the spacer’s pilot diameter, or use hub-centric rings to adapt them. You’ll also need to verify that the overall wheel and tire package won’t extend beyond your fender line or cause rubbing at full steering lock after the spacers are installed.
