Replace worn king pin screws on your HPI Racing SAVAGE XL FLUX with these GPM stainless steel units to improve steering precision. They are made for the front C hub and rear knuckles to tighten up movement and maintain consistent handling. Each screw has an M4 thread, accepts a 2.5mm hex driver and includes a 3.98mm plain section for correct seating. The 21mm overall length helps close gaps and supports smoother suspension articulation.
