ST Racing Concepts have released these CNC Machined aluminum front steering knuckles for the Ultima SC, SC-R, RB5 and RT5. Precision CNC Machined from high grade aluminum, they greatly increase the front suspension durability of your Kyosho off-road vehicles. The company’s new manufacturing procedure allows for the tightest tolerance in bearing fitment since the bearing holes are done after anodizing ensuring the bearing tolerance is not affected by the anodizing process. Available in gun metal, blue and limited edition red.
We reported previously on RPM’s new rear bearing carriers for the HPI Blitz and Firestorm lines of vehicles that incorporated 5x11mm bearings, improving durability and performance significantly. That same bearing size is now available for the front end of those same vehicles, with their new in-line steering blocks incorporating a 5x11mm bearing, which has nearly twice the dynamic load rating as the stock 5x10mm bearing, making a strong truck nearly bulletproof. These blocks incorporate all stock geometry for a perfect fit and are molded from the company’s ultra durable blend of nylons for a significant improvement in durability and strength as well.
