Billet aluminum is a great material for use in suspension applications as it has an immensely high strength to weight ratio along with a superior level of corrosion resistance compared to many other metals on the market. Unlike steel kits that are cut-out and welded together, our Pro-Billet kits are machined from a solid piece and will not bend or warp under even the most stressful conditions. We complete this kit with our heavy duty spring compressor. This compressor tool helps compress the spring on your strut making removal and installation a breeze. Each compressor tool comes with hardware to secure the tool safely to strut to prevent the spring from coming loose. All Supreme Suspensions products are developed and rigorously tested by in-house ASE certified specialists to ensure the proper road safety.NOTES: An alignment is always recommended after altering the height of your vehicle.*DOES NOT FIT MEGA CAB MODELS / REBEL MODELS / WARLOCK MODELS **NOT COMPATIBLE W/ 2013+ TRUCKS WITH THE ACTIVE-LEVEL FOUR-CORNER AIR SUSPENSION
