Boss Bearing 25-2060-5B Front Differential Seal Kit – Honda Rancher, Rincon & Rubicon

The Boss Bearing 25-2060-5B is a front differential seal kit designed for a wide range of Honda TRX ATVs, including Rancher, Rincon, and Rubicon models. It includes all necessary front differential seals — seals only, no bearings — making it ideal for a targeted seal replacement when your bearings are still in good condition.

Differential seals play an important role in keeping gear oil in and contaminants out. When they start to wear, you may notice fluid leaking from the differential or increased wear on internal components. Replacing the seals early is one of the easiest ways to extend the life of your front differential and avoid a more expensive repair later on.

Whether you're doing a full service or just addressing a leak, this kit gives you everything you need to get the job done right. Compatible with Honda TRX400FA, TRX400FGA, TRX500FA, TRX500FE, TRX500FGA, TRX500FM, TRX500FPA, TRX500FPE, TRX500FPM, TRX650 Rincon, TRX680 Rincon, and TRX700 Rubicon.
