Skyjacker Nitro 8000 Shock Absorbers are perfect for all vehicles, from stock-suspension sedans to the highest off-road machines. Their bodies are highly-charged with 150psi of nitrogen gas and will self-adjust depending on the driving conditions both on and off the road to guarantee the smoothest ride possible while enhancing your vehicle's handling characteristics! The secret of these shock absorbers is in their unique multi-stage velocity-sensitive valving which will work restlessly to ensure your ride remains comfortable at any driving speed. They feature a twin-tube construction for additional smoothness, while the 14mm heavy-duty rods ensure added durability. The shock absorbers are available in both front and rear sets in a variety of sizes. They come packaged with durable red polyurethane bushings and boots. Skyjacker Nitro 8000 Shock Absorbers are backed by a limited Lifetime Warranty.
