Product Overview
What is the most asked for drop amount in truck lowering history? Yes, you are correct, a 4/6 kit. Made famous by the 88-98 C1500, a 4/6 kit is almost a standard. Here, control arms are used with the factory spring to drop the front 4″ and a rear axle flip kit with frame supports gets you 6″ in the rear.
This is a very noticeable drop, heads will turn and when they do they won’t see a truck bouncing down the road with tires hitting fenders and passengers holding on for life! With this kit they will see a great looking truck riding smooth with hot wheels and tires and very happy people in the cab!
