RC 3.5 Series II Suspension vs RC 3.75 Combo
I've pretty much narrowed my choices down to these two lifts. I just dont see any reason to spend more on a Teraflex lift when nobody has anything but great things to say about Rough Country Lifts and their outstanding Customer Service. I'll be using it primarily as a DD with some moderate mud, trail, and some sand by the river. Which one do ya'll think is the better deal? Will the 3.5 inch lift need drive shaft mods? If so which ones? The price and size difference between the two is negligible, but which lift would be better for my use. I understand the body lift doesn't look wonderful to some people, but the gap doesn't bother me too much. At least a rear bumper lift is included to hide the space between the body and bumper. What are ya'lls opinions? Which do ya'll think will have the best ride? Thanks guys

My vote is for the 3.5 series II, I'm happy with mine. Depending on how much you wheel a new front driveshaft may eventually be in order. Make sure you give the guys at R/C a call and let them know your a forum member and they will do better on the price!

Did you end up having to buy a new driveshaft? And is it both front and rear or just the front drive shaft?

My vote is for 3.5 II. I am really happy with mine as well. No problems to mention. Installed last Jan. Only about 4,000 miles on current setup, but no issues. Cheers

I've read on the forums that if you put a 27.5" or longer shock on a 2012 Jeep, you will need a new driveshaft. From personal experience, I have a 3.5" RK xfactor mid arm suspension installed and I needed an aftermarket driveshaft because the stock driveshaft hit the crossover exhaust pipe and had such a steep angle at the transfer case that the CV boot was pinched. I bought a Coast driveshaft that barely cleared the crossover exhaust pipe. I ended up moving the crossover pipe anyways because the Coast driveshaft clearance was about 1/4" at full droop.
