Lift Kits - ReadyLIFT Suspension, Inc. 69-3005 Rating: 4 Stars

Not Much Difference.

Easy kit to install, but didn't really see much of a lift at the setting the instructions gave for the adjusting bolt. Will have the alignment rechecked to make sure it is good. If I were to change it again, I would spend the money and get a 4" lift kit.
