After this weekend I have started wondering if I need to add some longer coil springs to my Jeep. When I have issues it is because i get high centered. I have a 2014 JKURX (same as the 10th anniversary and hard rock editions). I currently have a 3" Mopar stage 3 lift, which comes with Fox Reservoir shocks, 6 fixed control arms (front uppers are stock), and limit straps. I have, but have not installed, an Artec Truss, control arm skids, gussets, and Synergy ball joints. I plan to go up to 37s within the next year or so. My question is can I go to a 4" or 4.5" coil spring instead of the 3" that are on there now? If so, what else do I need to change or add to make it work the best? Are there other options that will give a bit more clearance that will work as well or better?

FYI for those who want to know about weight - I have the original bumpers, 9.5cti winch, grill guard, PS Rocker Knockers, Rock Hard oil/trans skid plate, 35" spare with 18x9 wheel, Tera Flex tire carriers, and light bar.

 

With fixed length control arms you're not going to be able to get everything set properly if you add another 1.5". You're also looking at adding a drag link flip at that lift height. Point being, it won't be as simple as swapping springs. Is 2" of ground clearance really going to help you or could maybe picking a better line save you some money?

 

Yeah I'm sure picking a better line would work, but there are times when things don't work out as planned. This weekend for example, I'm on a Jeep Jamboree and the trail guide gives me the line to take, I take it, and this happens. In this spot I think 1.5" and 37s would get me over it. But, I'm not looking at spending a bunch of money right now anyway. Also, would a drag link flip give me reason to need the other version of the Artec truss?

 

It would depend which trackbar mount you ordered. The truss is the same regardless which mount you got, but you will need a higher than stock track bar mount with a draglink flip.
You're looking at a draglink flip, adjustable front lower arms, coils, and more than likely shocks.

 

And a driveshaft (rear should be ok, but maybe both?), if they are still stock. Longer links, if the current ones are not adjustable. Axle centering, if not adjustable.

Slap the 37's on, then see if you still get hung up?
