Gabriel FleetLine Cab Shock Absorber 83038 — Heavy-Duty Larger-Bore Design for Freightliner & Commercial Trucks

Gabriel FleetLine 83038 is a heavy-duty cab shock absorber engineered to reduce cab vibration and withstand commercial fleet duty for Freightliner and compatible chassis.

Built for Class 3–8 trucks, buses and commercial fleet vehicles, the Gabriel FleetLine cab shock delivers robust damping, corrosion-resistant hardware and a larger-bore design to handle sustained loads and rough roads. This model (83038) matches several OEM numbers used on Freightliner 122SD, Cascadia, Columbia, Coronado, M2 112 and select Pierce chassis so fleet managers and technicians can replace worn cab dampers with a proven heavy-duty option.

How does this shock improve driver comfort and reduce cab shake?

The FleetLine 83038 uses a multi-stage valving system and increased fluid capacity to smooth transient motions and minimize high-frequency vibration. That consistent damping helps reduce driver fatigue and keeps controls more stable during long hauls or when operating on uneven surfaces.

• 10-stage valving for consistent damping across speeds
• Bulged body increases fluid volume for cooler operation
• Multi-lip piston rod seal reduces leakage and extends service life
• Designed specifically to dampen cab vibration rather than suspension movement

What makes the FleetLine 83038 durable for heavy commercial use?

This shock was engineered with a larger 1 5/8" bore and solid steel eye rings to resist tensile failure under heavy loads. Protective finishes, a chromed piston rod and 360° arc-welded end mounts further reduce corrosion and mechanical wear in harsh fleet environments.

• Larger bore for improved tensile strength and longevity
• Chromed piston rod for corrosion resistance and better seal lubrication
• Anti-corrosion end mounts to limit rust at attachment points
• 360° arc-welded end mounts and solid eye rings for robust connection

Which vehicles and OEM numbers does this shock fit?

The Gabriel 83038 is manufactured to match multiple OEM part numbers used by Freightliner and Pierce, covering a wide range of cabs and sleeper configurations. Always verify compatibility by comparing the OEM number and mounting style to your vehicle before installation.

• Fits Freightliner 122SD, Cascadia, Columbia, Coronado, M2 112 and Century Class models
• Common OEM references: 18-41762-000, 18-60764-000, 814903003528 and related interchanges
• Compatible with select Pierce units built on Freightliner M2 112 chassis
• Confirm position, top/bottom mount codes (ES149/EB1), and stroke measurements before ordering

What are the key specifications and maintenance notes?

Size and stroke are critical for correct operation: the extended length, collapsed length and stroke must match the original unit. The FleetLine design reduces fade and provides consistent operation, but routine inspection of mounting hardware and seal condition will maximize service life.

• Extended length: 10.45 in; Collapsed length: 8.41 in; Stroke: 3 in
• Upper mount code ES149; Lower mount code EB1
• Formulated shock oil and durable piston seal to resist fade
• Inspect end mounts, rod finish and seals during service intervals

Who is this for: professional fleet managers, commercial vehicle technicians and owner-operators who need a direct-fit, heavy-duty cab shock that matches Freightliner and compatible OEM references. Choose the Gabriel FleetLine 83038 when you require a commercial-grade replacement that emphasizes durability, consistent damping and corrosion resistance for demanding on-road or vocational use.
