Note – this steering kit is designed to use 5.5mm ball-ends (included), JConcepts or Team Associated 3.5mm turnbuckles along with Team Associated #6535 ball-cups (available separately). While operating, testing, and driving this vehicle, the decision was made to design the steering around items which are better suited to racing conditions and modern durability.
One of the best hop-ups that can be made to the RC10 is to update the steering bellcranks 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 and solid design, increasing steering response and feel. The idler bellcrank sports a beefy and similar design giving the vehicle a symmetrical feel. The parts are available in blue or black anodizing and feature silver chamfered edged highlighting and laser-etched JC logo for brand authenticity.
The bellcranks are bearing supported with heavy-duty flanged bearings and include threaded standoffs. The threaded standoffs attach to the chassis nose piece first utilizing the included JConcepts 8/32” x 5/16” titanium screws and the rest of the assembly install and secure over the standoffs. An aluminum washer is included to secure the top end of the assembly with 4-40 x 5/16” FHCS. JConcepts also includes 5.5 x 4mm titanium ball-studs for each location on the aluminum steering hole locations.
Spencer Rivkin, Jason Ruona, and Paul Wynn tested and debuted the new steering system during the JConcepts ONS series round 1 in Savannah, Florida during the 2026 racing season. The team brought home several victories and podium results and tested the durability of the design on numerous occasions along the way. The new updated design assembles to all RC10’s after updating to 5.5mm ball-studs and #6535 ball-cups and to RC10 Factory Team as a direct replacement.
The JConcepts team builds, tests, and travels the world to support the brand and gathers valuable driver feedback in search of the best appearing and performance items on the market. The product is designed and formed in the U.S.A. and always backed by JConcepts customer service, supported, and developed by professionals with style.
