I have been looking for some type of adjustable spacer set up to compensate for the factory rake plus the additional sag due to my bumper and winch up front. Does anyone have any experience with the JKS coil over spacer set up? They look like a beefy part but a bit on the pricey side. I have a 2010 Wrangler Sport sitting on a set of Rubi take off springs and 33x12.50 tires. I'm on a budget and these spacers will blow it, but with the additional weight up front, I need more (about 2 inches) than the urethane spacers I have found seem to offer. I'm planning to do a 3.5 inch lift, possibly as much as 4.5, with a set of 35s or 37s as soon as this set of tires needs replaced and don't want to get a spacer kit that will be removed in the spring at the latest. Any input is appreciated.
