Product Highlights
Precision Damper Control: Restores the ability to adjust your Grammer seat's shock absorber, ensuring a smooth ride regardless of road conditions.
Reinforced Polymer Body: Manufactured from advanced self-lubricating nylon that resists mechanical fatigue and temperature fluctuations inside the cab.
Reliable Locking System: The high-tension spring and locking block are engineered to maintain their position, preventing the damper from drifting during long-haul drives.
Easy DIY Installation: Direct 1:1 replacement for the original Grammer 1150897 components, fitting perfectly into the side control panel of the seat.
⚠️ IMPORTANT: BUYER'S GUIDE (TECHNICAL VERIFICATION)
LEVER SHAPE: Grammer seats use several similar-looking levers. Verify the mounting socket and the "hook" profile of your old 1150897 lever matches our photos.
SPRING TENSION: If your seat's damper adjustment is loose, the internal spring is likely broken. This kit includes the exact heavy-duty spring required for a full repair.
MSG SERIES: Primarily designed for the **MSG 90** generation. Check the data plate on your seat base to confirm your MSG series number.
LUBRICATION: For maximum longevity, apply a small amount of synthetic grease to the moving plastic parts during assembly.
