2.5" or 3" lift help.
I would go with the TF 3" for the JKU. I got the TF 2.5" coils and read you generally get more lift then advertised. I actually got 3 1/8" in front and 2" in the rear. TF said this was normal. I ended up adding 1/2" spacers. I don't believe you will have to replace your driveshafts right away but I would start saving for one.
I started out with just the TF 2.5" coils. When they started sagging, I added a 1" spacer in the front and 1/2" on the rears. It just continued to sag, to the point that even with the spacers, my extended bumpstops were only an inch or two from touching the landing blocks. This past Saturday, I switched to the 2.5" RK progressive coils and kept the spacers installed. The bumpstops are a good 3"+ from touching down now. It is noticibly taller getting in, and the ride feels better also.
As for the driveshafts, I tore the front splineshaft boot at Rausch and the CV boot was just starting to sling grease, so I replaced it with a Tattons 1310. Front lower control arms have been replaced also.
Hmmm ok. I'm thinking I'm going with then RK 2.5" flex kit.
