hey guys, I have a 4" spring lift on my 97 jeep tj . the springs are from rough country and were on the jeep when i bought it. Well I just found some OME springs for a 4" lift and they are brand new OME939 and OME946 are the part numbers. and the price is 175.00 for all 4 springs. is that a great deal on these springs ?? and are the OEM springs SOOO much better than the rough country that I should buy these springs and change out the RC springs.?? The RC springs were put on 03/13/13
