Dual-Rocker Seat Adjustment Switch Specs

Heavy-Duty Pneumatic Design: Built to handle constant air pressure cycles, providing smooth and reliable adjustment for the driver's backrest and lumbar zones.
Reinforced Brass Inlets: Features high-strength brass air ports on the back to prevent air leaks and resist damage during installation and daily use.
Dual Rocker Precision: Two independent rocker switches allow for fine-tuned ergonomic support, reducing driver fatigue on long-haul trips.
UV-Resistant Grey Housing: The premium ABS plastic housing matches the original factory interior and resists fading/cracking over time.

ICON MATCHING: Check the "+" and "-" icons and the seat profile on the buttons. This switch is for both lumbar and backrest height.
GRAMMER 90.3 ONLY: This specific dual-button layout is designed for the Grammer 90.3 generation. Verify your seat tag before ordering.
AIR LINE CHECK: This is a pneumatic valve. Ensure your air lines are cut clean and squarely to ensure a 100% leak-proof connection to the brass stems.
SIDE VERIFICATION: Typically mounted on the side of the seat frame. Check orientation of the air port exits on the back to match your original part.
