Toyota 4Runner Coilover Suspension Kit - Front + Rear - ARB - Nitro Plus - '03-'09 is a direct-fit coilover kit designed for 2003–2009 4Runner models. This ARB/OME Nitro Plus set replaces the factory shocks and springs to provide adjustable ride height and improved load handling for street and off-road use.

The kit pairs Nitrocharger monotube dampers with progressive-rate coils engineered for the 4Runner's weight and geometry. Front units offer 1–2 inches of lift with spring rates up to 330 lb; rear springs provide approximately 2 inches of lift with a 660 lb rate. These components are built to work together to control body motion, support added weight from gear or accessories, and maintain wheel travel under varied driving conditions.

• Front lift range: 1–2 in; spring rate up to 330 lb
• Rear lift: ~2 in; spring rate ~660 lb
• Nitrocharger monotube shocks for consistent damping
• Direct-fit for 2003–2009 Toyota 4Runner front and rear
