What parts are included in this A-arm repair kit?

This kit includes all the necessary components to rebuild one upper A-arm. You'll find bearings, bushings, bearing shafts, seals, shims, and spacers within the package.

Do I need to buy more than one kit for my ATV?

Yes, you will need to purchase two of these kits. Each kit rebuilds only one A-arm, so you need two kits to service both the left and right upper A-arms on your Yamaha YFZ450R or YFZ450X.

Is this kit compatible with the Yamaha YFZ450X?

Yes, this QuadBoss A-arm repair kit is also compatible with the 2010 and 2011 Yamaha YFZ450X models, in addition to the YFZ450R.
