Rough Country premium N3 truck shocks offer you the best of both worlds: a smooth, comfortable highway ride with the performance and fade resistance you need to venture off road. Inside this shock absorber replacement, a nitrogen charge provides superior heat dissipation through the N3's 54mm shock body, while a chrome-hardened piston rod makes the shock durable enough to handle aggressive terrain. Built to military specifications, N3 shocks are rated to work in temperatures as low as -40 degrees Fahrenheit. Front and rear replacement shocks are available depending on your truck's needs. Whether you're on a long commute or exploring unpaved, muddy, rocky terrain, Rough Country premium N3 shock absorbers make a great upgrade to your truck's suspension system.
