Serpent 904225 steering lever shaft for Viper 990e R, steering linkage replacement  [SER904225]

Steering lever shaft for Viper 990e R

This Serpent SER904225 is the dedicated steering lever shaft for the Viper 990e R chassis (SER904008). It is an RC-scale replacement part intended to restore straightness and reduce play in the steering linkage when the original shaft shows wear or damage. The part is listed by its Serpent model number to match spares inventories and service needs for the Viper 990e R platform.

Installation note: this shaft replaces the worn steering lever pivot in the steering assembly and should be fitted so the linkage moves freely without axial play. During reassembly confirm alignment of the servo linkage and steering arms, and verify full range of motion before track use. The component directly affects steering feel and centering, so inspect for looseness after initial bench testing.

Maintenance and tuning role: while the shaft itself is a simple mechanical spare, swapping it during routine servicing removes a common wear point that can introduce steering slop. Replacing a degraded shaft helps preserve the intended steering response used for setup adjustments and fine-tuning of steering geometry on the Viper 990e R.
