Serpent 903890 rear wishbone upper bushings are a practical replacement for maintaining rear suspension integrity on the Viper 990R GP. These bushings are engineered to limit unwanted play and preserve handling consistency under load.
The tailored fit for the Viper 990R ensures the bushings sit securely in the suspension mounts, helping to stabilise the chassis. Reducing slack in the rear arms enhances steering precision and makes setup changes more repeatable for club and competition use.
