Show original supplier description

The Viking B258 Warrior double-adjustable rear shocks are engineered for 2015-2024 Ford Mustang models, including GT, Ecoboost, V6, and Shelby variants. These shocks feature 19 distinct settings for both compression and rebound, allowing for a total of 361 possible valving combinations to precisely tune your suspension for street or strip use. Constructed from highly durable and lightweight billet aluminum, the B258 shocks are built for longevity and performance. They are designed as a direct bolt-in replacement for the factory mounting location, simplifying installation. This kit includes a pair of rear shocks. These shocks are specifically designed for the S550 and S650 Mustang chassis and are compatible with stock height or vehicles lowered up to 3 inches. However, they do not fit Mustangs equipped with the factory Magnaride suspension system.
