The stock bottom overload spring is very harsh in spring rate, this mini pack is a progressive overload that will ride better and provide 1-3 inches of rear lift if one or both of the spacer blocks are removed.
Get better ride quality and the added height with one product. The mini pack is only compatible with the stock spring pack, and it fastens to the stock spring pack with a new center pin (included). Two (2) mini packs required per truck.
