Built for trucks and heavy-duty hauling, these Firestone air springs enhance suspension performance and handling during towing. They level the rear end under load and improve steering response while reducing tire wear. The 5 to 100 PSI range adapts to any cargo weight.

The frame-mounted design works with in-bed hitch systems, and manual fill capability lets you adjust pressure on site without an air compressor. This two-piece kit includes all mounting hardware for straightforward installation in about one hour.
