ZANURA Cab Shocks 2-Pack 83038 for Freightliner Cascadia — Direct-Replace Black Semi Cab Dampers

ZANURA 2 Pack 83038 cab shocks are direct-replacement suspension dampers engineered to restore cab stability and reduce vibration on compatible Freightliner models.

These semi cab shocks replace part number 83038 (compatible with Monroe 66122 and Freightliner OEM numbers such as 18-41762-000/002) and are sized to match factory dimensions for a straightforward swap. Built from plated metal with a protective black finish, they are designed to withstand heavy-duty trucking use while returning much of the original ride control and cab isolation characteristics. Below you’ll find practical answers to common buyer questions and clear specifications to confirm fitment.

What Freightliner models and years will these cab shocks fit?

How do the shock specifications affect performance and fit?

Key dimensions and operating specs determine physical fit and the shock’s damping behavior. Match the extended/collapsed lengths, stroke, and mount codes to the original part to maintain correct cab ride height and motion control.

• Includes dust tube and recoil cutoff for longevity in harsh conditions

What should I expect during installation and maintenance?

These are direct-replacement semi cab shocks designed for bolt-on installation using existing mount hardware in most cases. Minimal tools and basic mechanical familiarity are usually sufficient, but follow vehicle service procedures and torque specs when reassembling.

• Direct replacement—matches factory mounting points and hardware
• Black-coated metal body resists corrosion and road wear
• Inspect mounts and bushings; replace worn components for best results
• Test for correct cab travel and noise after installation
