Firestone 12352 Ride-Rite Air Helper Spring - Kit

The Firestone 12352 Ride-Rite Air Helper Spring Kit is a heavy-duty air suspension upgrade designed to improve load-carrying capacity, reduce sag, and restore ride quality when hauling or towing. Engineered by Firestone Industrial Products, one of the most trusted names in air suspension technology, this kit installs between the frame and axle to supplement existing leaf or coil springs.

Key Features:

• Heavy-duty air spring bellows constructed from durable, reinforced rubber compound
• Adjustable air pressure (0–100 PSI) allows you to fine-tune ride height and load support on demand
• Reduces rear-end sag caused by heavy payloads, fifth-wheel hitches, or gooseneck trailers
• Improves steering control, headlight aim, and overall vehicle stability under load
• Compatible with factory suspension — does not require permanent modifications
• Includes all necessary hardware, air lines, and instructions for a complete installation
• Works with single-path or dual-path (Ride-Rite Ultimate) inflation setups

The Firestone Ride-Rite system is a bolt-on solution that works in conjunction with your factory suspension rather than replacing it, preserving a comfortable empty ride while delivering robust support when loaded. This kit is backed by Firestone's reputation for quality and is made in the USA.
