Swapping out springs?

I have the Full Traction 3" kit and it sags a little bit too much for my liking and i wanted just another inch or so. I was thinking of swapping in RE 4.5" coils. To do this what control arms would I have to change the lower, upper, or both. I would add extended brake lines. What else would I need? Please just don't turn this into a discussion about how thats too high for a SA.

RE coils tend to provide actual lift a bit more than rated, so you would probably get closer to 2" more lift out of them. If you only want another inch, you should consider just adding 1" spacers on the the springs you have. But if you go with the RE springs, you will most likely need adjustable upper arms to set the geometry right.

I would install a SYE I was thinking since a majority of the sag is in front of putting 5.5" coils in front and 4.5" in back. Would that be a good setup or would they not sag much from engine weight, new bumper, winch etc. Or would you recommend 4.5" in front and 3.5" rear or 4.5" all around and spacer in front to compensate for sag. Also will I need lower control arms or just upper adjustables? Would I need extended bump stops too or are the FT kit ones fine?

I wouldn't swap in 4.5" RE springs since RE springs have such a high spring rate and will sit closer to 5". Your 3" components weren't designed for that high of a lift. If you're wanting to counteract sag just buy some .75" spacers or something. Those work well.

i would just buy a set of NEW RE 3.5 coils, they will give you PLENTY of lift and you could keep what you have now, probably just adj. your TC drop if you have vibes.

good luck,

John

X2 I would consider the RE 3.5" springs. Many guys run 35s with a properly set up RE 3.5".

What if I wanted to go 4.5" coils all around. What mods would I need on top of my full traction setup? Would the stock control arms work or would I be pushing the limit? If so what are good control arms for a reasonable price.

Well in order to do that much lift properly I would recommend a SYE and rear cv driveshaft. I would only to a TC drop temporarily with that much lift. You would need upper adjustable control arms front and rear to adjust the pinion angles. Adjustable lowers would be a good idea if you still want to stick to short arms. You'll either need adjustable trackbars or drop brackets if you don't have them already. Possibly longer travel shocks and or brake lines. You'll have to take measurements with the amount of flex you gain with 4.5".

When it comes down to it. If you want to do it right and make it easy, I would just buy a whole new lift kit. Go with the RE 4.5" Superflex kit. It is very complete. Worth the money and I'm sure you can get some cash back if you sell your current lift. You'll spend about the same amount of money if you buy new coils, control arms, etc. on your own to get 4.5" than you would have if you just got a lift kit.

YEP!! work smarter not harder!!

i'm running the RE 4.5 kit and JKS 1.25 BL and its great!! though i think i'm going to put a 1.75" spacer in the front to level it out but buy the kit b/c it comes complete with everything you need to run it properly.....if you go to www.4x4groupbuy.com you can get the RE 4.5" SF kit and it has AA SYE and a Tom Woods custom shaft that comes with it for FREE, call and talk to Jason he is the owner and will help you with everything....thats where i got most all my stuff from and have no regrets at all!!

Okay So I really dont want to head down that road of all thos extra things. If I put in the 3.5" RE coils how well do they retain their height and how much net lift will i actually gain?

the RE coils are known for NOT sagging and the 3.5 coils will actually give you around 4" to 4.5" of lift, i know my 4.5 coils gave me close to 5.5" of lift!
they are great coils
