Bora 2-Inch Wheel Spacers for RAM 3500 | Heavy-Duty 10-Lug Applications
Our 2-inch wheel spacers are precision-machined for RAM 3500 trucks equipped with 10-lug wheel patterns, delivering the aggressive stance and tire clearance heavy-duty truck owners demand. Each spacer is CNC-machined from 6061-T6 billet aluminum in the USA, engineered to handle the extreme loads of dually and single-rear-wheel 3500 configurations.
Whether you’re running oversized all-terrain tires, leveling kits, or aftermarket wheels with challenging offsets, these spacers provide the perfect solution for clearance issues while maintaining proper wheel geometry. We built these spacers specifically for the rigorous demands of one-ton trucks, from daily towing to heavy payload hauling.

Hub-Centric Engineering for 10-Lug RAM 3500 Applications
Every Bora wheel spacer for the RAM 3500 features our proprietary hub-centric design with a precision-machined 121.3mm center bore that registers directly on your truck’s hub face. This engineering approach transfers vehicle weight through the hub rather than the wheel studs, eliminating the vibration and premature wear common with lug-centric spacers.
The 10-lug bolt pattern (8×6.5-inch / 8×165.1mm) is cut to exact OEM specifications on state-of-the-art CNC machines, ensuring every stud hole aligns perfectly with your factory hubs. We pre-install and torque Grade 10.9 hardened steel studs that exceed SAE J1199 standards for heavy-duty truck applications. Each stud is thread-locked and tested to withstand the demanding loads of dually configurations and heavy towing scenarios.
Fitment & Compatibility for RAM 3500 Models
Direct Fitment Specifications
These 2-inch spacers are engineered for 2003-2024 RAM 3500 trucks with 10-lug wheel patterns, covering both dually and single-rear-wheel configurations. The spacers accommodate factory wheels, aftermarket steel wheels, and aluminum alloy wheels with proper backspacing.
For dually applications, we recommend verifying your inner and outer wheel clearances before installation. The 2-inch spacing provides optimal clearance for oversized tires up to 37 inches while maintaining safe turning radius. Single-rear-wheel owners often pair these spacers with our leveling kit spacers for complete suspension geometry.
Materials & Construction Standards
We manufacture every RAM 3500 wheel spacer from 6061-T6 billet aluminum, the same aerospace-grade material used in aircraft structural components. This alloy delivers an exceptional strength-to-weight ratio, withstanding the extreme loads of heavy-duty truck applications without adding unnecessary unsprung weight to your suspension.
Our CNC machining process maintains tolerances within 0.001 inches across all critical dimensions—hub bore, bolt circle diameter, and mounting face flatness. This precision eliminates the runout and vibration issues that plague cast or forged spacers. Each spacer undergoes multi-point inspection and is serial-numbered for quality tracking.

RAM 3500 Wheel Spacer Questions
Yes, our 2-inch wheel spacers are designed for direct fitment on 2003-2024 RAM 3500 dually models with 10-lug patterns. The spacers work with factory wheels and most aftermarket wheels that meet RAM’s backspacing requirements. For dually configurations, verify that your inner wheel clearance accommodates the additional 2 inches of spacing. We recommend checking your specific wheel and tire combination against our fitment guide, as some aggressive tire sizes may require different spacing on inner versus outer positions.
Absolutely. Our RAM 3500 wheel spacers are engineered to exceed the truck’s gross axle weight rating, with load testing confirming safe operation beyond 7,000 pounds per wheel. The 6061-T6 billet aluminum construction and Grade 10.9 hardened steel studs provide strength far exceeding factory requirements.
The hub-centric design transfers vehicle weight through the hub rather than the studs, maintaining the same load path as your factory wheel mounting. Thousands of RAM 3500 owners use our spacers for daily towing of fifth wheels, goosenecks, and heavy commercial trailers without issues. Proper installation and torque maintenance are essential for safe operation under all load conditions.
The spacer width you need depends on your tire size, wheel offset, and desired stance. For factory wheel and tire combinations with leveling kits, 1.5-inch spacers typically provide adequate clearance. The 2-inch option is our most popular choice for trucks running 35-37 inch tires or aftermarket wheels with aggressive offsets.
If you’re running 37-inch or larger tires, particularly with wider tread widths, 2.5-inch spacers may be necessary to prevent rubbing at full steering lock. We recommend measuring your current clearance between the tire sidewall and suspension components at full turn. Our <a href=”/spacer-calculator/”>spacer sizing calculator</a> helps determine the optimal width based on your specific wheel offset and tire dimensions.
Hub-centric spacers like ours feature a precision-machined center bore that registers on your RAM 3500’s hub face, centering the spacer before any lug nuts are tightened. This design transfers vehicle weight through the hub, exactly like your factory wheel mounting, eliminating vibration and ensuring proper alignment.
Lug-centric spacers rely solely on the lug nuts to center the spacer, which can create runout, vibration, and premature wear on wheel bearings and studs. For heavy-duty applications like the RAM 3500, hub-centric design is essential for maintaining ride quality and component longevity. The 121.3mm center bore on our spacers matches RAM factory specifications precisely.
We include a complete set of open-end lug nuts with every spacer kit, specifically designed for use with our 2-inch spacers on 10-lug applications. These lug nuts feature the correct thread pitch (M14x1.5) and seat style for RAM 3500 wheels.
The open-end design accommodates both factory wheels and most aftermarket wheels without interference. If you’re running aftermarket wheels with extended shanks or specialized seat designs, you may need application-specific lug nuts. Our included lug nuts work for the vast majority of wheel combinations. Always verify proper thread engagement and seat contact before final installation.
Perform an initial re-torque after your first 50-100 miles of driving following installation. This allows the spacers to seat fully and the lug nuts to settle under normal driving loads. After the initial re-torque, check all lug nuts at every tire rotation or approximately every 5,000 miles.
Use a calibrated torque wrench set to 130-140 ft-lbs for the spacer-to-hub studs and 135-145 ft-lbs for the wheel-to-spacer lug nuts. If you frequently tow heavy loads or drive in severe conditions, more frequent torque checks provide additional peace of mind. Our <a href=”/maintenance-schedule/”>maintenance schedule guide</a> provides detailed inspection intervals based on your driving conditions.
Wheel spacers themselves do not automatically void your RAM manufacturer warranty. Under the Magnuson-Moss Warranty Act, manufacturers cannot void warranty coverage simply because you installed aftermarket parts. However, if a warranty claim arises and the dealer can demonstrate that the wheel spacers directly caused the failure, that specific repair may not be covered.
Our hub-centric spacers maintain factory wheel bearing alignment and do not alter suspension geometry beyond track width, minimizing any potential warranty concerns. Proper installation according to our specifications is essential. We recommend documenting your installation with photos and keeping all torque records. Many RAM 3500 owners run wheel spacers without any warranty issues, particularly when professionally installed.
