John Deere Wheel Spacers – 10mm Bora Precision-Engineered Spacers

The 10mm thickness is ideal when you need minimal clearance adjustment, such as preventing tire-to-loader contact during turns or accommodating slightly wider tires without significantly altering your tractor’s track width. If you’re measuring less than half an inch of needed clearance, the 10mm option typically provides the solution.

For applications requiring greater spacing for larger tire upgrades, dual wheel configurations, or substantial implement clearance needs, our 15mm or 20mm options may be more appropriate. Measure the actual clearance gap you need to fill, then select the spacer thickness that provides that spacing plus a small safety margin.

While mechanically possible, we don’t recommend stacking spacers in agricultural applications due to the stress and vibration tractors experience during field work. Each interface between stacked components creates potential for loosening under heavy use.

If you need spacing greater than 10mm, we recommend purchasing our single-piece 15mm, 20mm, or 25mm spacers engineered as complete units. This approach provides superior strength and reliability compared to stacked configurations. If your application requires spacing beyond our standard offerings, contact our technical team to discuss custom manufacturing options.

After initial installation, re-torque all spacer mounting bolts after one hour of operation and again after 10 operating hours. This allows the joint to properly seat under load.

Subsequently, inspect mounting bolt torque every 50 hours during your first season of use. Once the spacers have completed a full season, incorporate inspection into your regular seasonal maintenance routine before planting and harvest periods. Check for any signs of corrosion, physical damage to the spacer body, or loosening of fasteners. With proper installation and periodic inspection, our spacers provide years of reliable service.

Wheel spacers are considered aftermarket accessories similar to wheel weights or tire upgrades. Installation typically doesn’t void your John Deere warranty, though any damage directly attributable to improper spacer installation wouldn’t be covered under factory warranty.

We recommend notifying your equipment insurance provider about any modifications to your tractor, including spacer installation. Most agricultural equipment insurers don’t consider wheel spacers a material modification affecting coverage, but documentation protects you in the event of a claim. Keep your installation records and torque specifications in your tractor’s service file.

Yes, our 10mm spacers work with both single and dual wheel configurations. For dual rear wheel applications, the spacers install between the hub and inner wheel, providing proper spacing for the dual wheel assembly.

When configuring dual wheels, ensure your total track width remains within John Deere’s specifications for your specific model. Excessively wide track widths can affect turning radius, transport width for road travel, and row spacing compatibility in crop applications. Consult your operator manual for maximum permissible track width before finalizing your dual wheel setup.

Our hub-centric design features a machined center bore that precisely matches your John Deere’s hub diameter. This centers the spacer and wheel assembly on the hub itself, just as your factory wheels center on the hub. The lug bolts then secure the assembly rather than providing centering function.

Hub-centric design eliminates vibration and maintains precise wheel alignment, critical for smooth operation and even tire wear. Lug-centric spacers rely on bolt tension alone for centering, which can lead to minor runout and vibration, particularly as fasteners settle during initial use. We exclusively manufacture hub-centric spacers for agricultural equipment due to the superior performance characteristics.
