The Monroe® Magnum® Cab Suspension Shock Absorber is a gas-charged unit designed for heavy-duty cab suspensions. It isolates the cab from the frame for a smoother, more comfortable ride and utilizes velocity-sensitive valving to deliver a new standard in driver comfort (most applications).
Engineered for Peterbilt cab suspension applications, the Magnum Cab shock isolates cab vibration for improved driver comfort. Its 10-stage valving and durable construction ensure consistent performance across a range of Peterbilt long-haul models.

- CONSISTENT RIDE: All-weather fluid handles extreme temperatures; larger 2-in. reserve tube holds more fluid (when required).
- EXCEPTIONAL HANDLING: 10-Stage valving tuned to each vehicle; larger 1-3/8-in. bore for efficient, consistent control (most applications).
- STRONG AND DURABLE: Shouldered and bonded bushings with sleeve; arc welds up to 360° for durability.
- LONGER SERVICE LIFE: PTFE-coated bearing and nitrocarburized piston rod for durability and long service life (most applications).
- REDUCED NOISE, VIBRATION AND HARSHNESS: Isolates impact-related NVH under most driving conditions.
