Fits

The Readylift 66-3012 Leveling Kit utilizes their time-tested torsion leveling key which is the strongest and safest leveling key system on the market. Combine the torsion key with these ultra-strong fabricated boxed upper control arms and 1-ton ball joints and you have an excellent leveling option offered at a great price!

Frame side pivots feature Readylifts proprietary new TCT bushings which are self-lubricating and engineered to last. These new bushings include "side biter" washers to aid in maintaining alignment settings. The free-floating bushing design eliminates friction which is the most common culprit of traditional bushing failure.
