Review on Monroe 58643 Adjust Shock Absorber by Doug Friedman

Installed on a 2007 f150 XL work truck. The truck is constantly loaded with tools and supplies and appears to have sunk a bit. Before installation I measured 37.5 inches from floor to wheel arch, after installation I measured 39.0 inches from floor to wheel arch. I believe these shocks provide additional support for the suspension, so 1.5 inches of lift is unlikely to occur if you're running an empty box. Installation is slightly more difficult than standard shock absorbers. The springs prevent the shock absorbers from being compressed. I installed them using the included scissor jack to raise the back of the truck at the receiver hitch and jack it up until the tires were almost off the ground. This required a block under the jack. Top with a screwdriver in place.
