General Spring add a leaf kits are an economical way to increase your trucks spring capacity and ride height without having to replace the entire leaf spring stack.  We offer both a long and short add a leaf to give you more options to help you get exactly what you need.  An additional feature are the tip inserts (squeak pads) on the end of the add a leaf which reduce friction and prevent squeaking while distributing the weight over the entire tip insert eliminating the shear point caused by metal on metal contact.  General Spring add a leafs are specifically arched, cut and punched for your vehicle and are not a one size fits all.
