Bora 10mm Dually Wheel Spacers – Precision-Engineered for Dual Rear Wheels
Our 10mm dually wheel spacers are precision-machined to provide the exact clearance dual rear wheel trucks need between inner and outer wheels. Whether you’re running aftermarket wheels with different backspacing or need to prevent tire rub on stock setups, these spacers deliver reliable spacing without compromising safety.
We engineer every 10mm spacer from aerospace-grade billet aluminum with a corrosion-resistant finish that stands up to road salt, mud, and extreme temperatures. The hub-centric design ensures perfect wheel alignment and eliminates vibration, while our proprietary stud design provides secure mounting that meets or exceeds OEM specifications.
Installation takes minutes per wheel with basic hand tools. Each spacer is CNC-machined to tolerances within 0.001 inches, so you get consistent fitment across all positions. We’ve designed these spacers specifically for dually applications where precision matters most.
- 10mm thickness provides optimal clearance for most dually wheel combinations
- CNC-machined from 6061-T6 billet aluminum for maximum strength-to-weight ratio
- Hub-centric design eliminates vibration and ensures proper wheel centering
- Corrosion-resistant anodized finish withstands harsh road conditions
- Pre-installed heat-treated studs rated beyond OEM load specifications
Engineering & Construction
We machine every 10mm dually wheel spacer from a single piece of 6061-T6 billet aluminum, the same aerospace-grade material used in aircraft components. This manufacturing process eliminates the weak points found in cast or forged spacers, giving you a product that won’t crack under the demanding loads dual rear wheel trucks experience daily.
The anodized surface treatment creates a protective oxide layer that resists corrosion far better than painted or powder-coated finishes. We’ve tested these spacers in salt spray chambers for over 1,000 hours with zero degradation, so you can count on them in snowbelt winters or coastal environments.
Fitment & Compatibility
Which Trucks Use 10mm Dually Spacers?
The 10mm thickness is our most versatile size for modern dually trucks. It’s the ideal spacing when you’re installing aftermarket wheels with 1-2 inches less backspacing than stock, or when you need to clear brake caliper upgrades on the inner wheels.
These spacers fit 8-lug dually hubs with either 8×6.5 inch (GM, RAM 3500) or 8x170mm (Ford Super Duty) bolt patterns. The hub-centric design matches your truck’s pilot diameter exactly, so the spacer centers on the hub before you tighten any lug nuts. This prevents the off-center mounting that causes wheel wobble and premature bearing wear.
Installation Process
Installing Bora 10mm dually wheel spacers requires only the tools you already have: a torque wrench, breaker bar, and socket set. We’ve designed the installation to be completely reversible, so you can remove the spacers anytime without modifying your truck.
Start by removing your outer dually wheels and cleaning the hub face thoroughly. Slide the spacer onto the hub until it seats against the mounting surface, then hand-thread two lug nuts to hold it in place. Install the remaining lug nuts and torque them to your truck manufacturer’s specifications in a star pattern.

Common Questions About 10mm Dually Wheel Spacers
You need 10mm spacers when your inner and outer dually wheels don’t have adequate clearance, typically due to aftermarket wheels with different backspacing than factory. The 10mm thickness is ideal for most modern trucks when you’re running wheels with 1-2 inches less backspacing than stock, or when you need to clear upgraded brake components.
Spacers also help when your tires rub together under load, which causes premature sidewall wear and potential tire failure. Proper spacing maintains safe clearance throughout the suspension travel range.
Yes, our 10mm dually wheel spacers are engineered specifically for the demanding loads dual rear wheel trucks experience during towing and hauling. We manufacture them from aerospace-grade 6061-T6 billet aluminum with heat-treated studs rated beyond OEM specifications.
The hub-centric design ensures weight transfers through the hub rather than the studs, exactly like your factory setup. Thousands of customers tow fifth wheels and gooseneck trailers daily with our spacers installed. As with any wheel component, proper installation and periodic torque checking are essential for safe operation.
Measure the clearance between your inner and outer tires at the closest point when the truck is loaded. If you have less than 15mm of clearance or if your tires make contact during suspension compression, 10mm spacers will solve the problem.
For aftermarket wheels, compare the backspacing to your factory wheels. A difference of 1-2 inches typically requires 10mm spacers to restore proper track width. Our fitment guide provides specific recommendations by truck model and wheel specifications.
Most truck owners install our 10mm dually wheel spacers themselves in 30-45 minutes with basic hand tools. You need a torque wrench, breaker bar, and socket set – the same tools used for regular tire rotation.
We provide detailed instructions with torque specifications for every common dually truck. The installation is completely reversible and doesn’t require any permanent modifications to your truck. If you’re comfortable rotating your own tires, you can install these spacers.
Our 10mm dually spacers are available for both 8x170mm bolt pattern (Ford Super Duty) and 8×6.5 inch bolt pattern (Ram 3500, GM 3500HD). The hub-centric design matches your specific truck’s pilot diameter for perfect centering.
When ordering, select the bolt pattern that matches your truck. Each spacer is machined specifically for either Ford or GM/Ram applications to ensure proper fitment.
Check lug nut torque after the first 50 miles, again at 100 miles, and then during your regular tire rotation schedule. The initial re-torquing accounts for the seating that occurs as the components mate under load.
We include thread-locking compound with every set to prevent loosening during the break-in period. After the first 100 miles, the spacers seat permanently and require only the same maintenance intervals as your wheels.
Billet aluminum spacers like ours are CNC-machined from a solid block of aerospace-grade material, creating a product with consistent grain structure and no internal voids. Cast spacers are poured into molds, which can create weak points and porosity that compromise strength.
Our billet construction process costs more but delivers superior strength, precise tolerances within 0.001 inches, and reliability under the heavy loads dually trucks experience. The difference becomes critical when you’re towing maximum capacity or hauling heavy payloads daily.
