How do the shock's dimensions and travel affect cab performance?

Length and travel determine how the cab moves over bumps and how the absorber damps that motion. This model’s measured extended and compressed lengths and two-inch travel are tuned for cab isolation and predictable rebound, helping reduce vibration and driver fatigue when mounted correctly.

• Extended length: 10.330 inches — full out position for clearance checks
• Compressed length: 8.330 inches — confirms fit in rest position
• Travel: 2.000 inches — designed to control cab oscillation and return
• Dust shield included to protect seal life and maintain damping consistency

Where does this shock mount, and can I install it myself?

The unit installs on either the left or right side of the cab depending on your truck’s layout. Professional installation is recommended for safety and proper torque settings, but experienced DIYers with the right tools can replace cab shocks by following factory procedures and verifying fitment and travel measurements.

• Installation position: Cab left or right (driver or passenger side)
• Includes dust shield to simplify handling during install
• Check match with referenced OEM numbers before installation
• Torque hardware to factory specs and test cab movement after fitting
