This is an optional RPM Front Bearing Carrier Set, and is intended for use with the Traxxas Electric Rustler, Electric Stampede, Bandit and Slash 1/10 vehicles. When your stock 5mm x 8mm bushings have worn out and your equally small bearings keep blowing up, RPM oversized bearing carriers are there to save you. These carriers allow the use of massive 5mm x 11mm bearings (the same used in stock nitro Rustler / Stampede trucks) to be installed on your E-version. Improved performance, less rolling resistance and less maintenance are all characteristics you can expect from these carriers and larger bearings.
NOTE: 5X11 BEARINGS are not included with these kits (4 bearings are needed for each kit). VXL & Slash owners: Your truck comes stock with 5x11mm bearings.
