One of the mods I have planned for my truck is a front end leveling kit. From the searching I've done, I have found three different ones...ReadyLift, Pro Comp, and Daystar. They range in price from $230 (ReadyLift) to $130 (Daystar). What is the reason for such a wide range of prices? Is the quality really that different? Could the "cheaper" ones possibly break or wear out somehow? Has anybody had experience with these brands?
