Differences between the B4 and B3 Kits

Here are several reasons why you should upgrade:

  • The B4's 2.60:1 gives higher torque capacity.
  • The B4's longer rear CVD dog bones and axles push the B4 out to maximum legal width for more traction.
  • All four of the B4's suspension arms are the same length.
  • The B4's hinge pins are "captured," eliminating E-clips.
  • The B4's angled bellcrank steering minimizes bump steer and maintains correct buggy Ackermann angles throughout the full range of suspension travel.
  • The B4 accepts trailing and inline front axles for more tuning options.
  • The B4's front tires are wider. The B4's wheels are stiffer and more responsive.
