Tough Dog Toyota Fortuner GD-6 (2016+) Complete 40mm Suspension Lift Kit
The Tough Dog Toyota Fortuner GD-6 (2016+) 40mm Suspension Kit is the definitive upgrade for owners who demand more from their SUV. Unlike the Hilux, the Fortuner features a rear coil-link suspension that can feel “soft” or “wallowy” when fully loaded with passengers, luggage, or towing gear. This kit delivers a firmer, more planted feel — significantly reducing body roll and eliminating the front-end nose-dive under braking that plagues the factory setup.
Built with 41mm Bore Foam Cell Shock technology, this kit is engineered for the long haul — keeping oil temperatures low and valving consistent through the toughest corrugated African roads, whether you’re on a school run or deep in the bush.
Front Springs: Heavy-duty Coil Springs — available for No Bar, Bullbar, or Winch setups
Rear Springs: Coil Springs — Comfort, 0–300kg, or Constant Load options (ideal for drawer systems and towing)
Full Hardware Kit: All necessary bushes and spacers for seamless bolt-on installation
Approx. Shipping Weight: 40kg – 48kg
Package Dimensions (L×W×H): 900mm × 450mm × 250mm
SKU: TD-FORT-GD6-40 (configuration specific)
🚗 Why Upgrade Your Fortuner GD-6?
The Fortuner is a versatile family and adventure vehicle — but its factory suspension is tuned heavily for unladen city comfort. Add a towbar, a full load of passengers and luggage, or an off-road trailer, and the rear end sags, the nose dives under braking, and body roll becomes a real concern. The Tough Dog kit restores ride height and keeps the vehicle level, safe, and composed — even when pushed to its limits.
✅ Optional 9-stage adjustable shocks — perfect for drivers who switch between daily city driving and weekend off-road adventures
