Traxxas Slash 2WD, Rustler, Stampede Heavy Duty Front Steering Blocks (2) by RPM Racing Brand New....Never Used...New in Box You are bidding on a pair of Front Bearing Carriers (Steering Blocks) for Traxxas Slash, Rustler or Stampede 2WD Trucks. The RPM Racing part number is # 80372 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. Tech Note: 5 x 11mm. Bearings are not included with these kits (4 bearings are needed for each kit). VXL & Slash owners: Your truck comes stock with 5x11mm bearings.
