Quadratec 2.5” Coil Spring Suspension Kit with FOX IFP Mono-Tube Shocks Reviews
Perfect kit without needing to upgrade to much in your Jeep. Best buck for your dollar.
Rides phenomenal with the Fox shocks. I also installed a Teraflex monster track bar. Lift gave me about 3.3 inches I’m assuming It’ll settle some.
I love this kit. It was time to replace the stock shocks and I wanted to increase the ride height. Perfect height, rides great, doesn't cause any unwanted esp issues. Very simple install too.
Questions
The Quadratec Morphic Wheels are a key part of making this work. These rims feature 5.2 inches of backspacing, which is about an inch less than factory wheels. This pushes the tire outward just enough to prevent the sidewall from rubbing against your suspension components or frame when you turn the steering wheel all the way to the "lock" position.
