Old Man Emu offers a range of tuned and matched integrated suspension kits to ensure the right suspension is selected for how the vehicle is outfitted and the conditions it will encounter. Old Man Emu suspension systems are designed to enhance ride quality, ride control, load-carrying capacity, and ride height. When building an off-road vehicle, it's best to notate the heavy parts that you plan to add. Heavy components will slowly begin to compress your suspension which results in vehicle sag. Choosing an Old Man Emu integrated suspension kit will avoid sag and ride discomfort as our engineers have tuned and matched suspension components for a range of different weights. Old Man Emu has an offering of 3 different shock absorbers to ensure that you can find an integrated suspension kit to suit your every demand, vehicle outfit and road condition. This suspension lift kit comes with Old Man Emu Nitrocharger shocks. Nitrocharger is a twin-tube design with the outer reserve tube providing protection to the internal components off road. Nitrocharger represents an excellent upgrade opportunity for any 4WDer seeking an increase in vehicle control and comfort, increased ride height, and load carrying capability. This suspension lift kit is tuned and matched for the Toyota 4Runner to provide 1-2in of lift in the front, with a weight of 0-330lbs and provide 2in of lift in the rear with a weight of 330lbs. ; Nitro Plus Kit FR 1-2 in/0-330 lb, RR 2 in/330 lb 2006K
