Molded composite RIGHT steering block redesigned for use with graphite Ackermann plate to allow greater Ackermann and bump-steer adjustment range. The tiny yet tough steering blocks are molded from super-tough, high-tech composite material. Thanks to superior molding tolerances, bearings fit perfectly into the steering blocks without any extra play, giving maximum stability and steering. Marked R for easy identification. The steering block also accommodates the optional graphite Aero Disc #335270 for improved steering.
