Engineered for Victory. Born from Competition. Introducing the RRP FSX RX4E Steering Blocks, developed through direct input from Team Rubrix drivers Alexander Funke and Scott Spear. Their race-proven experience helped shape the design, giving FSX its meaning: Funke–Spear–Rubrix.
Precision-machined from lightweight 7075 aluminum, the FSX Steering Blocks combine strength, reduced weight, and precise steering geometry. Updated to accept 6x12x3 bearings, they provide improved reliability, smoothness, and overall drivability.
