Bora 2″ Wheel Spacers for Ram 2500 – Heavy-Duty 8×6.5 Bolt Pattern
Our 2-inch wheel spacers are precision-engineered specifically for Ram 2500 trucks with the 8×6.5 (8×165.1mm) bolt pattern. Manufactured from billet 6061-T6 aluminum, these spacers push your wheels outward to create an aggressive stance while improving handling stability and providing clearance for larger tires or aftermarket brake kits.
Each spacer undergoes CNC machining to exact tolerances, ensuring perfect hub-centric fit on your Ram 2500. We’ve designed these spacers for both daily drivers and heavy-duty work trucks that demand reliable performance under load. The kit includes all necessary extended studs and lug nuts, so you have everything needed for a complete installation.
- 2-inch (50.8mm) width per spacer for 4-inch total track width increase
- Billet 6061-T6 aircraft-grade aluminum construction rated for 3,000+ lb load capacity
- Hub-centric design with 4.56-inch (116mm) center bore for vibration-free performance
- 8×6.5 (8×165.1mm) bolt pattern — fits Ram 2500 (2012-2024) and Ram 3500 SRW
- 14×1.5mm thread pitch with Grade 10.9 extended wheel studs included
Materials & Construction Quality
We machine every Bora wheel spacer from a single piece of 6061-T6 billet aluminum — the same aerospace-grade material trusted in aircraft components. This manufacturing approach eliminates weak points found in cast or forged alternatives, giving you consistent strength across the entire spacer body.
The CNC machining process holds tolerances within 0.001 inches, ensuring each mounting surface sits perfectly flat against your Ram 2500’s hub and wheel. Our black anodizing treatment penetrates the aluminum surface to create a protective layer that stands up to road salt, gravel impacts, and extreme temperature swings. We test every production batch to a load rating exceeding 10 times the wheel weight your Ram 2500 carries, providing a safety margin that matters when you’re hauling equipment or towing heavy trailers.
Fitment & Compatibility Details
These 2-inch spacers are engineered for Ram 2500 trucks from 2012 through current model year production, along with Ram 3500 single rear wheel configurations sharing the 8×6.5 bolt pattern. The 4.56-inch center bore matches factory Ram hub specifications exactly, creating a hub-centric fit that transfers vehicle weight through the hub rather than relying solely on lug nut tension.
Before installation, verify your Ram has the standard 8×165.1mm (8×6.5-inch) bolt circle — some early 2500 models used different patterns. The spacers add 2 inches per side, resulting in a 4-inch total increase in track width. This additional width provides clearance for tires up to 35×12.50 on factory suspension and accommodates most aftermarket brake upgrades that require extra caliper clearance.
Installation Process & Requirements
Installation requires removing your existing wheels and mounting the spacers to the factory hub using the included extended studs. Each stud threads into your Ram 2500’s existing hub threads and extends through the spacer, creating new mounting points for your wheels. We recommend using a torque wrench calibrated to 125-130 ft-lbs for the final tightening sequence.
The complete installation typically takes 90-120 minutes for someone with basic mechanical experience and access to a floor jack and jack stands. You’ll need a 22mm socket for lug nuts, a torque wrench, and thread locker (included in the kit). We provide detailed instructions with torque specifications and a proper tightening sequence to ensure even pressure distribution.

Common Questions About Ram 2500 Wheel Spacers
Wheel spacers themselves typically don’t void manufacturer warranties, but any damage directly attributed to improper installation or modification could affect coverage for specific components. We recommend consulting your dealer service department before installation if you have warranty concerns.
Our spacers are engineered to OEM quality standards and maintain all factory load ratings when properly installed. Many Ram 2500 owners use wheel spacers without warranty issues, particularly when installed by professional shops that document the work.
The right size depends on your specific goal. If you’re adding clearance for aftermarket brake calipers, measure the gap between your current wheel and the caliper — you need at least that much plus 1/4 inch safety margin. For aesthetic stance changes, 2-inch spacers provide a noticeable aggressive look with 4 inches of total track width increase.
For tire clearance on lifted trucks, mock up your desired tire size and measure how much additional space you need to clear suspension components. If you’re uncertain, our technical team can provide recommendations based on your exact wheel offset, tire size, and intended use.
You cannot use factory lug nuts with these spacers. The kit includes sixteen proper lug nuts specifically sized for the extended studs and designed with the correct seat angle for your wheels. Factory Ram nuts are too short to engage sufficient threads once the spacer is installed.
The included lug nuts feature the same 14×1.5mm thread pitch and conical seat as factory hardware, ensuring proper clamping force and wheel centering. Using incorrect lug nuts can cause wheel detachment or damage — always use the provided hardware or exact replacement nuts from Bora.
We do not recommend stacking wheel spacers. Each spacer is engineered as a complete system with specific stud length, thread engagement, and load distribution characteristics. Stacking compromises these design parameters and introduces potential failure points.
If you need more than 2 inches of spacing, we manufacture thicker single-piece spacers up to 2.5 inches for Ram 2500 applications. A single thicker spacer is always safer and more reliable than stacking multiple thinner units. Contact our team to discuss the appropriate single-piece spacer for your desired track width.
Our hub-centric design eliminates vibration when properly installed. The precision-machined center bore matches your Ram 2500’s hub exactly, ensuring the spacer and wheel are centered on the hub rather than relying on lug nuts for centering. This is the same mounting method used by your factory wheels.
Vibration issues typically result from improper installation, damaged wheel surfaces, or wheels that aren’t properly balanced. Following our torque specifications and re-checking lug nut tightness after 50-100 miles ensures trouble-free performance. Thousands of Ram owners drive daily on our spacers with zero vibration.
Retorque all lug nuts to 125-130 ft-lbs after your first 50-100 miles of driving — this initial settling period is standard for any wheel installation. Check again at 500 miles as a precautionary measure during the break-in period.
After the break-in period, verify lug nut tightness during your regular tire rotation schedule (typically every 5,000-7,000 miles) or whenever you remove wheels for seasonal tire changes. The included thread locker prevents loosening under normal driving conditions, so frequent checks aren’t necessary once the installation has properly seated.
Wheel spacers are legal for street use in all 50 states when properly installed and maintained. Some states require periodic vehicle inspections that include checking for loose or damaged wheel components — properly torqued Bora spacers pass these inspections without issue.
Our spacers meet SAE and ISO standards for automotive wheel attachment components. Law enforcement and inspection stations recognize professionally manufactured hub-centric spacers as legitimate vehicle modifications. Keep your installation documentation and torque records as proof of proper installation if questions arise during inspections.
