Description
Gabriel 83906 Fleetline heavy-duty cab shock absorber for Freightliner Cascadia, Columbia, Coronado, and 122SD. Direct replacement for Freightliner 18-69674-000 and 18-67845-000 at the cab-mount damper position — controls cab pitch and isolates the sleeper from chassis impulse on air-cab Freightliner conventionals. 10.45 in extended, 8.41 in compressed, 0.59 in rod, 12 mm upper mounting bolt.
Signs You Need a New Cab Shock
- Cab pitches or porpoises after expansion joints and bumps
- Driver-seat shake at highway speed disproportionate to the road
- Visible oil weep on the shock body or dust shield
- Audible knock on cold starts as the cab settles
- Cab corner sits low or noticeably crooked at rest

Replace cab shocks in pairs (left + right) to keep the cab tracking square. Confirm 12 mm upper mounting bolt and 8.41/10.45 in compressed/extended length before ordering — earlier and later Freightliner cab dampers use different mount geometry.
