The GPM ER2040R rear adjustable wheelie set is built from 6061 T6 aluminum to provide a durable platform for TRAXXAS E-REVO VXL rear lift control. The twin wheel layout improves stability under load while multiple mounting positions permit fine tuning of wheelie angle to match drivetrain setup and driving preference. The Delrin wheel components include preinstalled bearings for consistent rotation and the wheel profile is shaped to enhance traction where it matters.
