Built Strong Enough To Handle The Real Work

This RED Label Air Spring Kit is more than just a support system, it’s engineered from the ground up to withstand real-world abuse. Each kit uses four-layer commercial-grade rubber bellows built from the same material used in Firestone’s heavy-duty Airide systems, offering long-lasting performance in extreme conditions. Steel alloy brackets and grade 8 fasteners bring added strength and corrosion resistance, especially important when you’re driving through salted roads or harsh environments. It’s designed for 2WD and 4WD models and bolts directly between your truck’s frame and rear suspension without requiring any drilling. With a load capacity of up to 7,500 pounds and an air pressure range from 5 to 150 PSI, it offers serious adjustability to handle uneven or off-center cargo with ease. The included manual fill kit makes pressure adjustments straightforward and reliable. Whether you're hauling, towing, or just prepping your truck for whatever the road throws at it, this kit gives you the structure and control to do it with confidence.
