ReadyLIFT 6'' Lift Kit fits 2014-2018 Dodge Ram 2500 4WD Series diesel short bed trucks. ReadyLIFT Suspension This exciting lift system is Made in the U.S.A. and provides 6'' of front lift and features the best engineering technology you will find on the market today. The 49-1600 series 6" system utilizes performance front coil springs providing a true 6'' of front lift. In the rear, we use our proven spacer design technology to design heavy-duty 3.5" lift rear spacers which team up perfectly with the factory rear coil springs. This system includes a lift structure that will enhance and improve the overall factory ride while greatly improving off-road performance. Along with performance springs and spacers, our engineering team also developed rugged frame-mount radius arm drop brackets that reposition the factory radius arms back to the factory position. This is important so that the OEM alignment geometry can be retained. We also include heavy-duty fabricated steel front and rear track bar brackets, dropped cast iron front pitman arm, and front sway bar relocation brackets. We even include front/rear bump stop extensions to prevent over-compression during off-road use. Kit includes four (4) SST3000 Shocks. This new 6-Inch performance suspension system is designed specifically for the 2014-2018 Dodge Ram 2500 4WD trucks with diesel engines and will allow for increased tire packages up to 37x13.50 and 9.5" wide wheel sizes from 17-20" diameters.
