Serpent 903890 - Rear Upper Wishbone Bushing Kit for Viper 990R  [SER903890]

Refine Viper 990R Handling

The Serpent 903890 rear wishbone upper bushings are essential for owners servicing or upgrading a Viper 990R GP. They reduce play at the suspension pivots to deliver more consistent handling and improved longevity during competitive runs or weekend driving.

Tight Tolerances for Cleaner Steering

Made to mate precisely with the stock suspension components, these bushings stabilise the rear axle and cut unwanted movement in the arms. The result is firmer turn-in and steadier tracking, a practical upgrade for racers and serious hobbyists maintaining race readiness.
