Pinion Bearing & Seal Kit

One of the most common bearing failures in your front differential across all machines is the pinion bearing.  The reason for this failure is due to the high thrust ratings and torque loads these machines are able to put down.  Couple that with even greater horsepower and torque from the turbo units and you will find yourself with even more failures.  Fact of the matter is, the factory pinion bearings are just not up to the task!  We have spent years not only building and designing differential parts but also figuring out what works and what doesn’t for all the different units.  What this experience and research has led us to is the absolute best bearing setups for your particular application so that you do not have to worry about another pinion bearing failure again!

Our pinion bearing kits are insane! From the HD Pinion Bearing kit to the Xtreme Performance Pinion kit, you will not find another setup available on the market that will even come close to compare.  Both kits are WHISPER quiet!  What this means is that you will no longer have to listen to that rattle can sound coming from your front diff.  From the second you install either bearing kit in your differential, you will feel the difference.  Our kits are incredibly strong!  Yes, stronger than factory and stronger than any other kit available.  With the absolute highest load ratings available in their respective class, you just cannot find a stronger setup.  Our Xtreme Performance Pinion Bearing kit also comes sealed instead of open like factory.  What this means for you is longevity!  Our Xtreme Performance bearing kits will allow oil in but keep bigger metal shavings and particles out, thus helping to eliminate premature wear on the bearing.

WHAT KIT IS RIGHT FOR YOU?

While both our kits are great setups, some might wonder why we offer two different kits vs one, and also what kit is best for what unit.  Without a doubt, the best kit for all units is indeed the Xtreme Performance Bearing kit however, we know that is not always in every budget and some machines just are not treated as rough or have as much power as others.  So, as a guide this is what we HIGHLY recommend while choosing a kit.
