Product Review

Previously, RPM engineers designed 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! RPM In-Line Steering Blocks incorporate a 5x11mm bearing, which has nearly twice the dynamic load rating as the stock 5x10mm bearing. That's nearly twice the muscle to make a strong truck nearly bulletproof! RPM In-Line Steering Blocks incorporate all stock geometry for a perfect fit and are molded from our ultra durable blend of nylons for a significant improvement in durability and strength as well.
