Q: trying to increase the weight capacity of my 99 lightning. It has been lowered with springs in the front, shackles in the rear (BellTech) with Dosetech Shocks. Does anyone know what the difference is between the capacity of my 99 in stock trim versus the new 03/04 models with the heavier duty springs... can the rear leaf springs be swaped out easily?
I don't know about spring rates or fitment , but there are companys making small air bags that help the leafsout ,and
tou can add air to carry larger loads. appx. $200.00.
sorry I can't remember the name.
