Air Spring Supply Co. Airmax Kit — Toyota Fortuner 2016+ Heavy-Duty

Short Product Summary

The Air Spring Supply Co. Airmax Kit is a heavy-duty air-assisted rear suspension kit built specifically for the Toyota Fortuner (2016 onwards). It uses genuine industrial-grade air springs to support the rear axle once the vehicle is loaded, and bolts on without any cutting, drilling or welding.

Why This Product

Loading a Fortuner with camping gear, a trailer or a roof tent often pushes the rear suspension past what the factory springs were designed for, leading to sag, poor handling and headlights that point at oncoming traffic. This kit adds an air-assisted spring on each side of the rear axle, so you can add pressure only when you need extra support and release it again once the load comes off, through a fitment that leaves the original suspension untouched.

Key Features

• Genuine Firestone air springs – industrial-grade construction built for heavy, repeated loads
• Bolt-on fitting – no cutting, drilling or welding needed to install
• Fully reversible – removes cleanly if you sell the vehicle or change kits later
• Heavy-duty mounting brackets – top and bottom brackets built to handle constant flex
• Purpose-built for the Fortuner – engineered for 2016-onwards models specifically
• Complete fitting kit – tubing, valves, connectors and fasteners all supplied together

Ideal For

• Fortuner owners who tow extra support for a loaded caravan or trailer on the rear axle
• Overlanders carrying heavy gear levels the vehicle when the boot and roof are loaded
• Owners wanting a reversible upgrade bolts on and off without permanent changes to the vehicle
