For years the 69-1040 4" SST lift kit has been the go-to bolt-on lift system for Ram truck owners and has served these customers very well. Always striving to improve our product offering we have recently upgraded this popular lift kit with all-new tube steel upper control arms that feature our TCT non-bonded maintenance-free pivot bushings with side-biter washers and heavy-duty 1-ton ball joints. These Gen 2 control arms will ensure excellent ride and suspension geometry while ensuring a long life of maintenance-free operation. While our classic 4" SST Lift Kit does not require longer rear shocks customers with aging trucks have often asked ReadyLIFT for a rear shock replacement.
