RRP RaceX RX4E Complete Steering Bell-Crank Set RRP-121XG 
 
Rubrix RaceX: Crafted by Champions. Performance you can trust. Our complete RaceX RX4E Aluminum Bell-crank set is a direct fit for RRP RX4, RXD, and RMX platforms.
 
After extensive evaluation, Rubrix Racing engineered a fully CNC-machined, all-aluminum steering system that replaces the traditional multi-piece layout with a one-piece driving bell-crank design. By eliminating the servo saver, this upgrade delivers sharper steering response and a more connected driving feel.
 
The new bell-crank features a beefed-up, symmetrical design for enhanced durability and consistent handling balance. Precision matters: each unit supports 5×8×2.5 mm bearings and includes threaded aluminum steering posts to ensure accurate fitment and a clean, professional finish. Available in blue, black, and silver, each set is finished with a laser-etched RRP logo, reinforcing authenticity and premium craftsmanship.
