This is the Essentials* bearing kit by Avid RC for the R1WURKS R1B Mark 1 Dirt and Carpet Editions.*The Essentials kit removes the bearings that don’t typically need replacing such as the (4) 5x9x3 and (4) 3x7x3 steering rack bearings and the (2) 5x8x2.5 bearings in the ball diff. You can always make a custom kit by shopping for the bearings individually but the Essentials kit quickly saves you money.
