I was looking over a few different Mopar parts websites and found a few different part #'s for the front coil springs for 2013-2014 1500 4x4's. 5154615AA, 5154616AA, 5154617AA 5154622AA, 5154623AA, 5154624AA 5154629AA, 5154630AA, 5154631AA Does anyone have any information about spring rates? or if they are for the Left or Right. The 2 or 3 websites I looked at didn't specify left or right or give any spring rates. The description was the same for all the part numbers, "4WD W/O AIR SUSPENSION." The only difference was the spring codes at the end are different (example: ZVH, ZUJ, ZGC, ZFJ). For the Jeep JK, there were a lot more spring part numbers and the higher the number, the higher the spring rate. This meant the higher the part#, the higher the Jeep sat. Each higher number gave about a 1/4" lift. So some with X models could get 3/4" to 1.25" lift up front depending on what stock springs they had. I was hoping I could do the same with mine. Maybe get a 1" lift using higher part# stock coil springs to avoid any BS at the dealership down the road. Anyone have any knowledge or experience with these part numbers and their differences?
