One of the best hop-ups that can be made to the RC10 is to update the steering bell-cranks with a more durable design. JConcepts has evaluated the options and built an all aluminum design bringing the driving bell-crank into a one-piece design eliminating the servo saver, increasing steering response and feel. The idler bell-crank sports a beefy and similar design giving the vehicle a symmetrical feel. The parts are available in blue or black and feature silver chamfered edged highlighting and laser-etched JC logo for brand authenticity. The bell-cranks are bearing supported with heavy-duty flanged bearings and include threaded aluminum steering posts with etched JC logo for an ultra snug fit and finish.
