Here is my summary on the Rocky Road YJ spring lift, for those who might find it helpful. Again, thanks to those who did previous write-ups with suggestions on tools, etc! I previously had a BDS 2.5" spring under lift with slightly longer shackles. I was never happy with ride, even with the tires aired down and adjustable shocks. But our roads are very rough. I went with the spring under 3.5" OME kit with heavy duty front and rear, and the cheaper shocks. RR recommended heavy duty front and rear (I was hesitant on the rear because soft ride was the goal). In the front, I have a c channel front bumper with a 8274 winch with steel cable and a simple pipe grill guard. In the back I have a rear tank, bumper w/ swing out tire carrier, 33x10.50 tire, and highlift jack. Overall, the installation went ok. Some spacers were missing from the kit, but RR sent me the missing parts for free and without much explaining. There was a lot of drilling, so sharp bits, cutting fluid, reamers were necessary. A 90 degree drill also came in handy. I also had to do some welding and bracing on my rear shackle hanger (they aren't replaced with kit) since they had bent inward and cracked at the rear cross member location. Also one of my spring hangers was not welded on centered with frame, so that needed a lot of grinding to allow the bracket to slide over it. Finally, even though it is not limited to this lift, the stock shock mounts on the frame are just not wide enough for modern shocks...I kinda wish I had done the front shock tower relocation while I had all my tools out. The front sits noticeably higher than the BDS did but I did also lose about 50lbs up there with my winch mount change. The whole jeep is also alittle higher. The front shackle ended up about where it is supposed to (bottom slightly angled forward). The rear shackle is straight up and down despite the weight listed above, full tank of gas and a 50lb hitch basket attached. I don't have any shims on the front, and the alignment came back ok (although I am still suspicious of it). The rear springs clear the gas tank skid plate on the rear with some trimming. I haven't flexed it out yet, so more trimming may be necessary. I only have a few miles on it at this point and the ride is softer. It didn't do anything for the bucking, but that is life with short wheelbase. Once I break in the springs, I'll repost about the outcome and whether it was worth it.
