Superlift 4" + RC 2"?

So.... I am finally installing my SL 4", and I am looking at the old RC 2".
The 2" kit has no issues and I was thinking why not combine them?!

Has anyone done this? Considered it?
I upgraded the superlift with adjustable upper rear control arms, beefed up front CV axles, tom woods dbl cardon front Drive shaft, new front upper control arms.
Other than new 6" front and rear swaybar adds, what am I missing?

I don't know enough to advice you eitherway. Personally, I think combining two lift kits has the potential for things going very wrong.

Those driveshafts can only go to certain angles before they chew themselves up, same with the tie rods. As well, as they get close those critical angles, they may NOT break, but the stress goes up 10 fold and thus they wear very quickly. So at least the front, with the independent suspension, you're pushing it going so high.

Then there is the whole suspension how it will react and especially now with the high center of gravity.

Maybe it would be fine, and you won't get yourself in trouble if you know what you're doing. I could see it going bad also, either chewing parts in no time or bad reactions from the suspension.

Thanks for the thoughts, I had some of the same. I have given myself 72 hours to mull it over.

The only reason I think it may be feasable is that I have an older 2" kit that is just a pair of daystar spring spacers. Whereas the SL kit adds the component pieces that basically moves the whole system 4".
I was thing at the end of the SL install it is basically back to the stock tolerances, in regards to geometry.

Shouldn't the spring spacer kit be the same now, geometry, for effect on the new suspension?

I will post a pic of what the strut looks like on the ground

Granted, I have not switched to the OME springs yet, so that is stock spring with 2" spacer and SL 4" bracket
