This is the Essentials bearing kit by Avid RC for the TLR 22X-4.
The Essentials kit removes the bearings that don't typically need replacing such as the (4) 3x6 and (4) 5x8 bearings in the steering. You can always make a custom kit by shopping for the bearings individually but the Essentials kit quickly saves you money.
Includes:
8- 10x15x4 Revolution
4- 5x10x4 Revolution
4- 5x13x4 Revolution
2- 8x14x4 Revolution
