Suspension Leveling and Mild Kits are one of the most popular aftermarket products for truck owners. Leveling and Lift systems not only transform trucks into taller, better looking vehicle, but they also provide a more commanding view of the road. Suspension kits from ReadyLIFT Suspension Inc., the leader in suspension leveling systems, are the most economical and safe method of altering vehicle ride height, which also allows the consumer to upgrade his tires to a preferred larger size. Nothing looks better than a truck fit with an aggressive stance and that is exactly what ReadyLIFT Smart Suspension Systems (SST) provide! The 66-5912 extension provides 3.0" of front lift and is designed to create a "prerunner" stance with the front end sitting slightly higher than the rear. Due to popular demand from customers, we are now offering this 3.0" front strut extension kit as a means to give you the opportunity to give your truck the popular prerunner stance without the high cost of a typical prerunner suspension. This kit provides clearance to add up to 32.5" wheels and tires to 2wd & 4wd and PreRunner trucks. 33' tires can be used with some minor trimming of the inner fender panel.
