I rebuilt my front and rear suspension last year and used stock springs on front and back. Everything has leveled out but the rear sits about 1 1/2-2'' higher than i like. Are their aftermarket springs that are not shorter than 2''? What are my other options?

Is heating the spring up an aption?

are you sure they used stock rear springs? Stock rear springs (even new ones) will definitely not sit up high...

Do you have air shocks? If so, let some air out!
