RPM Traxxas Steering Blocks are the perfect solution for worn bushings and weak 5x8mm bearings. Give your electric the same bearing the nitro trucks come stock with - 5x11mm! The oversize bearings have higher load ratings than a 5x8mm bearing and will significantly increase the time between maintenance. In addition, these oversized bearing carriers are so strong, RPM guarantee that they won't ever break! When used in conjunction with the RPM Rear Bearing Carriers (RPM80382), you'll never have to worry about worn-out bushings or blown wheel bearings again!
