Firestone 551872 Air Helper Spring Kit

The Firestone 551872 air helper spring is designed to provide enhanced load support and improved ride quality for trucks, SUVs, and commercial vehicles. This air spring system works with your vehicle's existing suspension to help level your vehicle when hauling heavy loads or towing trailers.

Key Features:

• Adjustable air pressure allows customization based on load requirements
• Helps eliminate squat when towing or hauling heavy cargo
• Improves vehicle stability and steering control under load
• Reduces wear on suspension components by distributing weight more evenly
• Durable construction designed for demanding applications

Firestone air helper springs install between the frame and axle, providing progressive load support that increases as you add air pressure. The system can be inflated or deflated to match your specific load conditions, giving you control over your vehicle's ride height and handling characteristics.
