The GPM LUX021 spindle set is CNC oriented hardware machined from 7075 alloy to ensure consistent bearing alignment and increased stiffness in the steering knuckle assembly for the TEAM LOSI 8IGHT-X. Improved shaft concentricity minimises CVD runout and reduces dynamic misalignment under load, yielding steadier steering input and enhanced durability under frequent use. Recommended as a high quality upgrade for tuners seeking longer lasting, performance oriented components.
