Adjusting the sway bar pre-load has always seemed to be a bigger job than it should be. You have to jack up the car, turn the wheel, loosen one jam nut and tighten the other. Now there is a better way. This adjuster is simple to install and use. One will fit easily on any chassis. No need to jack up the car. To adjust, use a 3/8" drive wrench on the top and simply turn in or out to pre-load. a thread drag adjuster prevents it from moving on its own. Just slide it in and weld the threaded bushing in place.Pit Stop USA offers Howe Sway Bar Adjuster 23997 at low everyday prices.
