Bora 1.75″ Wheel Spacers – Premium Aluminum Bolt-On Spacers
Our 1.75 inch wheel spacers are precision CNC-machined from aerospace-grade 6061-T6 aluminum for superior strength and corrosion resistance. Each spacer provides exactly 1.75 inches of additional track width per side, improving vehicle stance while creating clearance for larger tires and aftermarket brake upgrades.
We engineer every Bora spacer with a hub-centric design to eliminate vibration and maintain factory ride quality. Grade 10.9 studs are pressed and thread-locked into each spacer, meeting or exceeding OEM specifications for safe, reliable performance. These bolt-on spacers install between your hub and wheel, using your factory lug pattern on both sides for a secure, balanced fit.
Ideal for trucks and SUVs requiring moderate width adjustment, our 1.75″ spacers accommodate wheel offset changes without the expense of new wheels. The anodized finish resists road salt and weather exposure, ensuring long-term durability in all driving conditions.
- 1.75 inch thickness per spacer (3.5 inches total track width increase)
- 6061-T6 billet aluminum construction with CNC precision machining
- Hub-centric design for vibration-free installation
- Grade 10.9 pre-installed wheel studs with thread-lock compound
- Bolt-on installation using factory lug pattern both sides
Materials & Construction Quality
We manufacture every Bora 1.75″ spacer from solid 6061-T6 aluminum billet, the same aerospace-grade alloy used in aircraft structural components. This material offers an exceptional strength-to-weight ratio—significantly stronger than cast aluminum while remaining lightweight enough to avoid adding unnecessary unsprung mass to your suspension.
Our CNC machining process holds tolerances within 0.001 inches, ensuring perfect hub-centric rings and lug hole alignment. Each spacer receives a Type II anodized finish that penetrates the aluminum surface, creating a protective oxide layer resistant to salt spray, UV exposure, and extreme temperatures. The pre-installed studs are manufactured from grade 10.9 steel and pressed into the spacer body with industrial thread-lock compound, creating a permanent bond that prevents stud rotation under torque.
Fitment & Compatibility
Bora 1.75 inch spacers are available in vehicle-specific configurations matching your factory lug pattern and hub bore diameter. We produce spacers for 5-lug patterns (including 5×4.5, 5×5.0, 5×5.5), 6-lug patterns (6×5.5, 6x135mm, 6×139.7mm), and 8-lug heavy-duty applications (8×6.5, 8x170mm, 8x180mm).
Our hub-centric design requires precise matching of your vehicle’s hub bore. Each spacer features a machined pilot ring that centers on your hub, plus a recessed face that centers your wheel—eliminating the wheel wobble common with lug-centric designs. When you select your vehicle during checkout, we automatically match the correct bolt pattern, hub bore, and thread pitch for your specific year, make, and model.
Installation Requirements
Installing Bora 1.75″ wheel spacers requires standard hand tools and follows a straightforward bolt-on process. You’ll need a torque wrench, properly rated jack and jack stands, and the specific lug nut size for your vehicle. We include detailed installation instructions with torque specifications for both the inner mounting nuts (securing spacer to hub) and outer wheel nuts.
The installation sequence begins with mounting the spacer to your hub using the provided inner lug nuts. These must be torqued to your vehicle’s factory specification—typically 85-100 ft-lbs for light trucks, higher for heavy-duty applications. Once the spacer is secured, your wheel mounts to the spacer’s pre-installed studs using the included outer lug nuts. We supply open-end lug nuts that allow proper seating on extended studs.

Common Questions About Bora 1.75″ Wheel Spacers
Yes, when properly installed and torqued to specification, our 1.75″ wheel spacers are completely safe for daily driving, towing, and off-road use. We engineer each spacer from 6061-T6 aluminum with grade 10.9 studs that meet or exceed OEM load ratings. The hub-centric design ensures proper load distribution and eliminates vibration. Follow the included torque specifications and retorque schedule for optimal safety and performance.
Bora 1.75 inch spacers are compatible with most stock wheel and tire combinations, though fitment depends on your specific vehicle. The spacers add 1.75 inches of offset per side, moving wheels outward by a total of 3.5 inches track width. You’ll need to verify that your fenders provide adequate clearance and that wheel barrels don’t contact brake components. We recommend test-fitting before final installation, and our technical team can provide specific guidance for your vehicle.
Hub-centric spacers like our 1.75″ Bora models use a precisely machined pilot ring that centers on your vehicle’s hub, exactly like your factory wheels. This design eliminates vibration by ensuring perfect wheel alignment. Lug-centric spacers rely only on lug nuts for centering, which can cause wobble and uneven wear. We manufacture exclusively hub-centric spacers because they maintain factory ride quality and safety standards. Each spacer is vehicle-specific to match your exact hub bore diameter.
We recommend retorquing all lug nuts after the first 25-50 miles of driving following initial installation. This allows hardware to fully seat after thermal cycling. After that, inspect and retorque during every tire rotation—typically every 5,000-7,500 miles. Also retorque whenever wheels are removed for any service. Use a calibrated torque wrench set to your vehicle’s factory specification for consistent clamping force and long-term reliability.
We do not recommend stacking multiple wheel spacers together. Stacking compromises the hub-centric design and can create unsafe loading conditions on studs and mounting surfaces. If you need more than 1.75 inches of spacing, we offer thicker single-piece spacers including our 2.0″ model. Using a single spacer of the appropriate thickness maintains proper engineering tolerances and ensures safe, vibration-free performance. Contact our team to determine the correct thickness for your application.
Wheel spacers themselves do not automatically void your vehicle warranty under the Magnuson-Moss Warranty Act. However, if a manufacturer can demonstrate that spacers directly caused a specific failure, that repair may not be covered. We engineer our 1.75″ spacers to OEM standards using grade 10.9 hardware and hub-centric designs that maintain factory suspension geometry. Many customers install spacers on new vehicles without warranty issues. Keep all documentation and installation records for your protection.
You’ll need a torque wrench (critical for proper installation), vehicle-appropriate jack and jack stands, tire iron or impact wrench, and basic hand tools. We include all necessary lug nuts and hardware in your kit. The installation process is straightforward for anyone comfortable with changing tires. Follow the included instructions carefully, paying special attention to torque specifications which vary by vehicle. If you’re not confident in your mechanical abilities, we recommend professional installation at a qualified shop.
