Product Highlights
NTS2 System Essential: Specifically designed for the second-generation for ISRI NTS platform. This linkage is the most common failure point when the height handle loses its "grip" on the air valve.
Reinforced Geometry: Our replacement features enhanced structural ribs at the pivot point to prevent the cracking and bending that occurs in aged original components.
Smooth Pneumatic Control: Restores the 1:1 mechanical linkage between your adjustment handle and the 947519 air valve, ensuring immediate and precise seat height response.
Industrial Grade Polymer: Manufactured from self-lubricating, high-density polymer to withstand the heavy torque and repeated cycles of a professional driver's seat.
⚠️ IMPORTANT: BUYER'S GUIDE (TECHNICAL VERIFICATION)
