This differential kit gives you the seals, gaskets, and bearings you need to keep that final drive running smooth and quiet, protecting the gears that transfer power to your wheels. Whether you’re hearing whining in turns or seeing oil where it shouldn’t be, this kit puts things right.

Built for Real Farm Work

This kit covers a wide range of John Deere tractors from the mid-range 6M and 6R series utility tractors up through the powerful 8000 and 9000 series machines. Whether you’re running a front loader, pulling heavy tillage equipment, or operating high-demand implements, these tractors put serious stress on differential components. The kit handles everything from daily chore work around the farmyard to seasonal field operations where dependable power transfer is critical.

Made to Last

These seal materials resist hardening and cracking from age and heat cycles, while maintaining the flexibility needed for proper sealing. Each component is manufactured to exact tolerances for reliable performance season after season. The double-lip design provides redundant protection—keeping lubricant in while excluding contaminants.

Good to Know

Differential rebuilding requires cleanliness above all else—any contamination causes rapid seal failure. Lubricate with clean gear oil during assembly and take your time with installation. Replace all seals in the kit even if some look okay—they’ve all seen the same service hours. If you’re not comfortable with the repair, this is one job where a good mechanic pays for himself in the long run.
