Toyota 4Runner Coilover Suspension Kit - ARB - Nitro Plus Kit - `03-`09 is a direct-fit coilover upgrade for 2003–2009 4Runners designed to improve load handling and adjustability. This ARB/OME Nitro Plus Kit combines nitrogen-charged shocks with tuned springs for dependable on- and off-road performance.

The kit provides a modest front lift range and a fixed rear lift, helping maintain factory geometry while allowing for additional tire clearance and improved control when carrying gear or towing. Built around Nitro Plus shocks, the dampers use pressurized nitrogen to reduce fade under repeated use. Springs and valving are chosen to work together for better resistance to bottoming and improved chassis control without harsh ride quality. This is an ideal choice for enthusiasts who want a durable, vehicle-specific suspension upgrade without guessing spring rates or shock lengths.
