i have my truck leveled with the bilstein ride height adjustable shock (5100 series) and using the stock spring... i was wondering where i could find a aftermarket spring that wont drop my truck or are for a lifted application,, i want to keep the same stock spring size, but just have a stiffer spring rate so i can put a heavier bumper up front.... if anyone can help me with this it would be greatly appreciated, ive looked all over, even called ford for coil spring dimensions to try get a custom one but no luck...
