Review on LIFT 57237 LoadLifter Air Spring by Jose Perry

This kit is designed to replace the overload springs on a K30 with a GVW of 9000lbs. At the same time, the ride height is adjustable so that the headlights are correctly aligned. It also reduces unsprung weight, which improves ride quality. Installation is easy after vehicle preparation. I had to remove the spring clips and u-bolts to remove the top overload spring and spacer and shorten the center bolt. I also shortened the U-bolts. I hid the filling lines in front of the bumper, the hose length is perfect. I routed the hose up and under the bed's corrugations to prevent damage. Five stars now. Towed a 7500 lb trailer perfectly straight.
