RPM has finally releases the new Caster & Steering Blocks for these Traxxas 4wd trucks. They started with a blank slate, drew in the necessary design elements and built an all-new design with a focus on punishment survivability. The core design of their caster blocks revolve around the lower-case “H” structure which provides extreme rigidity to keep camber and caster setting locked in place while running normally, yet their materials provide serious impact absorption characteristics to prevent breakage when those “oops” moments inevitably arise.
RPM steering blocks have also been reengineered for durability, strength, rigidity and crash-survivability. More material surrounds the kingpin posts while smoother flowing turnbuckle arms assure consistent feel and performance from the steering system.
