I have a 2003 Silverado (121,xxxMI) with the stock suspension and is in serious need of replacement. My leafsprings are no longer in a "U" shape they are more of a "W" . And when i hit a speed bump the truck bounces for like another 10 seconds and the leafspring bushings make a horiable squeeking nose that drives me nuts!! I do like the thought and look of a lowered truck like mine. So to my question, what is more inexpensive to replace all of my shocks, coils and leafsprings with?An"oem" replacement (to return it to stock height) or just buy a lowering kit to replace my stock suspension? And what brand do yall prefer to use for an "original" suspension replacement and a lowering kit suspension? I donot have a problem replacing everything by myself, ive replaced one before on a Jeep wrangler.
