Superior Load Support for Nissan Armada

If you use your Nissan Armada or Infiniti QX56 for towing or heavy hauling, the Firestone Coil-Rite Air Helper Spring Kit (Part #4150) is an essential upgrade. These air springs are engineered to fit inside your factory coil springs, providing a customizable air-cushioned suspension that prevents sagging and improves handling under load.

Why Choose Coil-Rite?

• Variable Spring Rate: Adjust air pressure to suit your specific load, from daily driving to heavy towing.
• Leveling Capability: Corrects rear-end squat to maintain proper headlight aim and steering geometry.
• Enhanced Safety: Improves braking effectiveness and stability during lane changes or cornering while loaded.
• Long-Lasting Durability: Made from high-grade, elastic polyurethane designed to withstand harsh road conditions.
• Easy Adjustability: Simple inflation valves allow you to alter performance in seconds.

The Coil-Rite system is designed to support between 500-1000 lbs. per set (within vehicle GVWR), making it perfect for families towing campers, boats, or utility trailers. By reducing inter-leaf friction and providing a progressive spring rate, you will notice a smoother, more controlled ride regardless of how much gear you are carrying. Installation is straightforward, allowing you to get back on the road with confidence. Find the best suspension solutions for your SUV at GGCRACING.
