When you want the alignment checked, get back with me.
I don't go along with heating springs, even temporarily.
Before you cut a coil spring, the suspension really needs to be measured first...............and your truck will be different from an FWD import.
Measuring is the key to lowering a vehicle using OEM springs and stock adjusters. I may be the only one on TR that knows how to measure a vehicle suspension to analyze how to safely lower it with OEM springs.
Lowering the back is quick with leaf removal, and it will soften the harsh ride of a truck somewhat.-Bob
