I have a 2014 JKU with 4" lift and adjustable short arm from Teraflex. I have purchased a Teraflex long arm kit and waiting on getting it installed to make sure I have everything else I need for me to make sure it is done right the first time. My question is since I am not running coil overs, do I need some kind of limiting straps or spring retainers to keep my coils in place when flexing? I am new to the Jeeps but always been in the custom truck scene. I just don't want to get out on a trail or course somewhere and have something go wrong because I didn't have everything I needed. I already have sway bar disconnects, extended brake lines, axle trusses, and Fox 2.0 shocks with reservoir for 3.5-6" lift ready to be installed with long arm kit. Already on Jeep I have adjustable front track bar, front and rear driveshaft with u-joints, and 1 ton steering flip kit. Is there anything else that I need to purchase before having it all installed other than coil overs? I plan on buying some coil overs at much later date since they are so expensive and already spending so much as is.
