This GPM MX030 knuckle and pull rod kit is an aftermarket, RC-scale component designed for the LOSI PROMOTO-MX platform. Machined from 7075-T6 aluminum, the parts aim to offer firmer steering inputs and improved durability compared with stock plastic components while keeping installation straightforward for hobby-level maintenance.
The kit includes larger inner bearings to reduce play at the steering joint, and the package supplies the matching 4x10x4 bearings for direct replacement. These parts are intended for use on LOSI 1/4 PROMOTO-MX motorcycle RTR models, including the PRO CIRCUIT variant, and should be used only on RC models.

For builders wanting a metal upgrade to steering components on the PROMOTO-MX, this kit supplies replacement knuckles and pull rods plus bearings to tighten steering feel and support tuning of suspension geometry without altering motor or electronics setups.
