I've had the Rockfather 2 in for almost 4 years and I've noticed that the front is beginning to sag some with the weight of the bull bar.
When I bought the lift, the only option for the front was medium duty, which I felt would be sturdy enough for the bull bar.
I got the parts in last week and swapped out the rears in a couple of hours (I am NOT a mechanic so I just take my time and make sure it's all SAFETY FIRST). Actually, it's only after a long time of studying the various threads on this site that I have finally worked up the nerve to do this at all.....
I don't have a garage, so right now I'm waiting for good weather (rainy and cold lately, almost made it down to freezing last night).
So, what I am actually putting in are: OME 927 springs up front with NS131 struts; OME948 springs rear with N132 shocks. I'm also planning to go with 2 conduit nuts per side.
So, it seems the only difference for the rear, between the RF2 and the OME lift is the oversized shocks that came with the RF2. I seem to have lost about 3/4" of lift with the OME. Noddabiggie IMO. Overall gain over stock is still about 2".
Okay, so until I get the new fronts in, currently I am running the RF2 front (OME medium duty with NS131 struts) and the OME rear, i.e: OME medium duty with a slightly tired front end. I can honestly say I like the configuration of the KJ better without its butt so high in the air, and the ride is noticeably nicer with the new rears. Those OME shocks seem really dynamic.
Do I need any extra rear bumpstops with this setup? I'm not into extreme offroading but I still get into flexy situations now and then.
