I just had our guys install the pro Comp 2.5" levelling kit in my 2014 1500 double cab 4x4. prior to install the front measured 36.5" and the rear was dead on 39". Installed measures 39" on all four corners with stock 18" wheels and tires. The kit I purchased on Amazon for $165.00(187.00 to my door), labour to install and align was 2.0 hrs. @ $130.00/hr. flat rate. The truck rides great, a little tighter in the front end, no unwanted noises, headlights will need to be adjusted. Tire sizing is next up.
