Nitrocharger Plus Suspension Kit with 1–2 in Front Lift, 2 in Rear Lift, 0–330 Front Load Rating, and 660 lb Rear Load Rating for 4th-Gen 4Runner (2003–2009)

The Nitrocharger Plus Suspension Kit offers a coordinated suspension upgrade for 4th-Gen 4Runner owners who want comfort and control for off-road and overland use. With 1–2 inches of front lift and 2 inches of rear lift, the system pairs with a 660-pound rear load rating to accommodate vehicles carrying additional weight.

The Nitrocharger Plus kit uses a tuned and matched configuration designed to work together. This integrated approach helps improve ride quality and control across changing road surfaces, from everyday driving to uneven trails.

Nitrocharger shocks use a twin-tube design, with an outer reserve tube that helps protect internal components during off-road use. This construction suits vehicles that regularly encounter rocks, ruts, and other challenging terrain.

A 5-position spring-seat adjustment, supported by coil seat spacers, allows the front suspension to accommodate a range of setups. This adjustability provides flexibility when configuring the 4Runner for its intended use and equipment.

Heavy-gauge steel tube construction adds strength for demanding off-road use. Combined with the protective twin-tube shock design, it supports a durable setup for drivers who regularly take their 4Runner beyond paved roads.
