Don’s Alien Arms are very well designed and the craftsmanship is absolutely world class. The install is more complex than installing short arms but it is not too bad as long as you have a competent welder complete the welding. Huge improvement in ride and overall feel of the truck! I installed these on a 3” lift and the small sharp edge bumps that use make the whole truck shudder are now absorbed and go almost unnoticed. Roll steer is greatly reduced as well. Highly recommend!
