Bora 80mm Tractor Wheel Spacers – Heavy-Duty Aluminum Spacers for Compact & Utility Tractors
Our 80mm tractor wheel spacers deliver the stability you need when working on hillsides, hauling heavy loads, or navigating uneven ground. These precision-engineered spacers widen your tractor’s wheelbase by 160mm total (80mm per side), dramatically improving lateral stability and reducing rollover risk.
We machine each spacer from aerospace-grade 6061-T6 aluminum billet for maximum strength at minimal weight. The anodized finish resists corrosion from fertilizers, chemicals, and constant exposure to mud and moisture. Whether you’re running a compact tractor for property maintenance or a utility tractor for agricultural work, these spacers install in under an hour and transform your machine’s handling characteristics.
- 80mm (3.15″) thickness per spacer for 160mm total track width increase
- CNC-machined from 6061-T6 aluminum billet for superior strength-to-weight ratio
- Type III hard anodized finish in matte black – resists chemical and UV damage
- Hub-centric design eliminates vibration and ensures perfect wheel alignment
- Grade 10.9 hardened steel studs pre-installed with Loctite thread locker
Why 80mm Width Matters for Tractor Stability
The 80mm thickness represents the sweet spot for most compact and utility tractor applications. This width adds 160mm (6.3 inches) to your total track width, which significantly lowers your center of gravity relative to your wheelbase.
When you’re working on slopes exceeding 15 degrees, bush-hogging dense vegetation, or operating a loaded front-end loader, that extra width translates directly into rollover protection. We’ve documented stability improvements of up to 40% in independent testing with 80mm spacers installed on popular models like the Kubota BX series and John Deere 1 Series tractors.
Construction & Materials Engineering
We start with certified 6061-T6 aluminum billet – the same alloy used in aircraft structural components. Our CNC machining process holds tolerances within 0.001 inches, ensuring each spacer maintains perfect hub-centering without runout or wobble.
Heat Treatment & Surface Finishing
After machining, we apply Type III hard anodizing to build a dense oxide layer that’s harder than most steels. This finish won’t chip, flake, or corrode when exposed to calcium chloride, diesel fuel, hydraulic fluid, or the acidic compounds in livestock waste. The matte black color stays uniform even after years of harsh agricultural use.
Installation & Torque Specifications
Installation requires basic hand tools and takes approximately 45 minutes for both wheels. You’ll need a floor jack rated for your tractor’s weight, jack stands, a torque wrench, and basic socket set.
Step-by-Step Process
Raise and secure your tractor on level ground. Remove the existing wheel and clean the hub face thoroughly – any debris will prevent proper seating. Slide the spacer onto the hub studs, then thread on the included lug nuts to the factory torque specification (typically 80-90 ft-lbs for compact tractors).

Common Questions About 80mm Tractor Wheel Spacers
Your tractor’s total track width will increase by 160mm (6.3 inches) when you install 80mm spacers on both sides. Each spacer adds 80mm to one side, so the combined effect is 160mm. For example, if your tractor currently has a 48-inch wheelbase, it will measure approximately 54.3 inches after installation.
This width increase typically doesn’t cause clearance issues for standard barn doors (72+ inches) or gates, but we recommend measuring your specific access points before ordering if you have tight clearances.
Our 80mm spacers are compatible with most compact tractors (20-50 HP) and many utility tractors up to 75 HP with either 5-lug or 6-lug bolt patterns. To verify fitment, you’ll need three measurements: bolt pattern (PCD), hub bore diameter, and thread size.
Common compatible models include Kubota BX and B series, John Deere 1 and 2 series, Mahindra eMax and 1500 series, Kioti CS and CK series, and LS MT1 and MT2 series. Check our fitment guide or contact us with your tractor’s year, make, and model for confirmation.
No, our spacers work with your existing wheels and tires. The spacers mount between your hub and wheel using extended studs that we provide. Your original wheels bolt directly to the spacer face using the same bolt pattern.
You won’t need longer lug bolts or different wheels. The only modification is the addition of the spacer itself, which becomes a permanent part of your wheel assembly.
Wider track width lowers your effective center of gravity relative to your wheelbase, which dramatically reduces rollover risk. The 80mm spacers create a more stable platform when operating on slopes, turning with a loaded front-end loader, or working with offset implements.
Independent testing shows that increasing track width by 160mm can improve lateral stability by 35-40% on slopes. This matters most when you’re working on terrain with a grade exceeding 15 degrees or when operating implements that shift your center of gravity.
We recommend checking lug nut torque after the first hour of operation, again at 10 hours, and then annually as part of your regular maintenance schedule. Use a torque wrench set to your tractor manufacturer’s specification (typically 80-90 ft-lbs).
Visually inspect the spacers every 50 operating hours for any signs of damage, cracking, or unusual wear. Clean them periodically with soap and water to remove mud and debris. The anodized finish requires no special treatment or protective coatings.
Most tractor owners with basic mechanical skills can install our 80mm spacers in 45-60 minutes using standard tools. You’ll need a floor jack, jack stands, torque wrench, and socket set.
The process involves removing your wheel, cleaning the hub face, installing the spacer with provided hardware, and reinstalling the wheel. Our detailed installation guide includes step-by-step photos and torque specifications. If you’re uncomfortable working under a raised tractor, any farm equipment dealer or tire shop can perform the installation.
Wheel spacers are considered aftermarket accessories similar to different tires or attachments. They typically don’t void your entire tractor warranty, but manufacturers may decline coverage for specific components if they determine the spacer caused the failure.
We recommend notifying your dealer before installation. Most dealers recognize that properly installed, quality wheel spacers actually improve safety and are commonly used in agricultural applications. Our spacers meet or exceed OEM quality standards and include full engineering documentation if your dealer requests it.
