Bora Wheel Spacers for John Deere Tractors | Precision-Machined Aluminum
Our Bora wheel spacers for John Deere models are engineered for professionals and property owners who demand precision fit and lasting durability. Each spacer is CNC-machined from aerospace-grade 6061-T6 aluminum, delivering the strength needed for loader work, mowing, and field operations without adding unnecessary weight to your tractor.
Designed specifically for John Deere bolt patterns and hub profiles, these spacers provide exact center-bore tolerances that eliminate vibration and maintain bearing life. We machine every unit in-house to meet OEM standards, ensuring compatibility with factory wheels and maintaining your tractor's warranty coverage. Whether you're widening stance for hillside stability or clearing larger implements, Bora spacers install with factory hardware and torque specifications.
What makes Bora spacers the right choice for your John Deere
Materials and construction standards
We manufacture every Bora wheel spacer from 6061-T6 aluminum billet—the same aerospace-grade material used in aircraft landing gear and high-stress automotive applications. This temper delivers 45,000 psi tensile strength while keeping weight low enough that your tractor’s axle bearings see no measurable load increase. Each spacer begins as a solid block; we remove material through precision CNC milling rather than casting, which eliminates the porosity and weak points common in cast spacers.
The hub-centric design uses a machined center register that pilots directly on your John Deere hub face. This transfers weight through the hub rather than the wheel studs, preventing the stud fatigue and loosening issues you’d see with lug-centric designs. We hold center-bore tolerances to ±0.002 inches, matching the fitment precision John Deere uses in factory wheel production. The Type III hard-coat anodizing we apply after machining penetrates the aluminum surface, creating a ceramic-like layer that stands up to hydraulic spray, fertilizer salts, and the abrasion from gravel roads and field debris.
Sizing and stance considerations for John Deere models
Choosing the right width for your application
We offer Bora wheel spacers in three widths: 1-inch, 1.5-inch, and 2-inch per side. The 1-inch option adds 2 inches to your total track width and suits operators who need modest clearance for larger rear tires or want to improve stability on gentle slopes without altering the tractor’s footprint dramatically. Most owners running a Bora spacer setup on the 1025R choose the 1.5-inch width, which adds 3 inches total track and provides noticeable improvement in loader stability when lifting pallets or moving round bales.
The 2-inch spacers are preferred for hillside mowing and properties with steep terrain. Adding 4 inches to your track width lowers the center of gravity enough that you’ll feel the difference immediately when traversing side slopes with a loaded bucket or pulling a heavy implement. We recommend measuring your current wheel-to-fender clearance and implement swing radius before ordering; the wider spacers may require minor fender trimming on some John Deere models, particularly 1-series compacts with factory turf tires.
Installation and torque specifications
Bora wheel spacers install using your existing John Deere wheel studs and lug nuts—no extended studs or custom hardware needed for the 1-inch and 1.5-inch widths. You’ll mount the spacer to the hub first, torquing the factory lug nuts to John Deere’s specification (typically 90-110 ft-lbs for compact models). The wheel then bolts to the spacer’s outer face using the same lug nuts, torqued to the same specification.
For 2-inch spacers, stud engagement drops below the minimum safe thread count on some models, so we include extended wheel studs with those kits. You’ll press out the factory studs and install the longer replacements—a 20-minute job per wheel with a basic arbor press or heavy hammer. We provide step-by-step instructions with photos keyed to specific John Deere series, and our tech support line can walk you through fitment questions for unusual wheel or tire combinations. Re-torque all lug nuts after the first hour of operation and again after 10 hours; this seats the spacer against the hub face and takes up any microscopic settling in the anodized finish.

Common questions about Bora wheel spacers for John Deere models
The 1-inch and 1.5-inch spacers install using your factory John Deere wheel studs and lug nuts without modification. The factory studs have enough thread engagement to safely torque the wheel through the spacer thickness. The 2-inch spacers reduce thread engagement below the recommended minimum on most John Deere compact models, so those kits include a set of extended studs that you press into the hub to replace the factory studs. Extended stud installation takes about 20 minutes per wheel with a basic arbor press or heavy hammer and drift punch.
Wheel spacers themselves do not void your John Deere tractor warranty. They are considered an accessory modification similar to adding aftermarket wheels or tires. However, if a dealer determines that a spacer directly caused a failure—for example, improper installation leading to bearing damage—that specific repair may not be covered under warranty. We design Bora spacers to maintain factory load paths and bearing preload, so when installed correctly and torqued to specification, they do not impose abnormal stress on drivetrain components. Always follow the installation instructions and torque specifications we provide.
Your ideal spacer width depends on your typical work and terrain. For general stability improvement and modest tire clearance, the 1-inch spacers add 2 inches total track and work well for flat to gently rolling properties. The 1.5-inch option is our most popular choice; it adds 3 inches total track and noticeably improves loader stability and hillside confidence without requiring fender modifications on most John Deere models. Choose the 2-inch spacers if you regularly work on steep slopes, use a front-end loader for heavy lifting, or need maximum rollover protection. Measure your current wheel-to-fender clearance before ordering the 2-inch option, as some compact models may require minor fender trimming.
Yes, you can install spacers on both axles, and many operators do exactly that for maximum stability improvement. Installing spacers on the rear axle alone widens the rear track for better hillside grip and reduces the risk of rear-end sliding on slopes. Adding spacers to the front axle improves loader stability and steering control, particularly when lifting heavy loads. If you plan to space both axles, we recommend starting with the rear and evaluating handling before adding front spacers. Some operators prefer to run wider spacers on the rear than the front to maintain a slight rake in the track width, which can improve turning radius on tight mowing patterns.
Bora spacers are compatible with both factory John Deere wheels and most aftermarket wheels, provided the aftermarket wheel matches the John Deere bolt pattern and has a hub-centric bore. The spacer mounts to your tractor hub using the factory bolt pattern, and the wheel mounts to the spacer's outer face using the same pattern. If your aftermarket wheels have a larger center bore than the John Deere hub diameter, you may need hubcentric rings to center the wheel on the spacer. We stock rings for common oversize bores. Verify that your aftermarket wheel has adequate clearance inside the barrel for the spacer thickness; some deep-dish wheels have limited inner clearance.
Retorque all lug nuts to the John Deere specification (typically 90-110 ft-lbs for compact models) after the first hour of operation, then again after 10 hours of use. This initial retorque sequence allows the spacer to fully seat against the hub face and takes up any microscopic settling in the anodized finish and mating surfaces. After the 10-hour retorque, check lug nut torque every 50 hours or seasonally as part of your regular tractor maintenance. If you hear any new vibration or notice a wheel wobble, stop immediately and check all lug nuts for proper torque before continuing operation.
Yes, when properly installed and maintained, Bora spacers are safe for road transport at typical tractor speeds. The hub-centric design transfers load through the hub rather than the wheel studs, which is the same load path John Deere uses in factory wheel mounting. Our 6061-T6 aluminum construction exceeds the strength requirements for agricultural tractor applications. Always verify that lug nuts are torqued to specification before any road travel, and inspect spacers visually for cracks or damage as part of your pre-trip check. If you regularly travel on public roads at speeds above 20 mph, recheck lug nut torque every 25 hours of operation.
