Nitrocharger Plus Suspension Kit with 2.5 in Front Lift, 2 in Rear Lift, 0 lb Front Load Rating, and 880 lb Rear Load Rating for 5th-Gen 4Runner (2010–2024)

The Old Man Emu Nitrocharger Plus Suspension Kit provides a complete solution for vehicles carrying heavy rear loads. The system is engineered to preserve front and rear suspension geometry, maintain ride comfort, and optimize handling both on-road and off-road. Nitrocharger twin-tube struts and shocks protect internal components while providing consistent damping, and the integrated design ensures that vehicle performance remains stable under significant rear weight.

The suspension kit is tuned to optimize articulation, stability, and ride height for vehicles carrying substantial rear weight. Spring rates and damping characteristics are calibrated to ensure precise control, preventing sag and maintaining a balanced ride while the front suspension remains unloaded.

All components are engineered to withstand harsh off-road conditions and heavy payloads. Protective outer tubes safeguard internal shock elements, and corrosion-resistant finishes preserve performance over time. The system is designed to endure both trail and highway use under load.

Five-position spring seat adjustment and included coil spacers allow fine-tuning of rear ride height and preload. These enable customization for different vehicle configurations and heavy cargo setups, ensuring the suspension maintains proper geometry and performance.

The Nitrocharger Plus Suspension Kit is a direct replacement for original equipment or compatible aftermarket suspension systems. Installation is accomplished with standard hand tools, and all required hardware and spacers are included to ensure proper fitment.
