Just put 2" and middle setting 5100s with STOCK UCA and no CB grinding on my 07 4x4, i can fit my fingers between the coil bucket and UCA. If you keep her mostly on the road, you will be perfectly fine, dont let people freak you out. yea i have some minor cuts in my CB now, but theyre like a 1/16th of an inch, and not serious. You'll feel it when it hits but you have to basically be getting your wheels off the ground, like when you get the pit of your stomach feel off a hill hop.

YOU SHOULD BE MORE THAN FINE with your RC UCAs, dont let some folks freak you out

As far as rough ride, i kept the stock springs on mine, RIDES GREAT, i wanna replace the rear shocks now because now when i go around the turn, you can feel the back of the truck sag, while the front stays up, feels like i can just swing the back around and drift the sh!t out of it if i wanted.

ALSO i can tell you, you WILL DEFINITELY need Cam Bolts, i got the prgs and when you order with your spacer, he refunds $29. and you need endlinks

 

He is an 05 Titan...doesn't his come with cam bolts?

 

Yes, 04-06 titans have cam bolts according to PRG's website

 

Pro4x are too stiff in general

 

I have an 04 with 08 springs and bilsteins on middle setting.It is a little firm,but not terrible.
I am planning on installing rough country UCA's,leveling spacer and moving the shock to the lowest setting just to see if I can retain the lift and soften it up some.

 

It's funny everyone is going in the opposite direction I am lol, my plan is 04 2wd with 2.5 spacer to keep same height, softer ride

 

I am very interested to hear how that goes, you will have to post up! I have a Pro4x and I have them on the lowest setting. I want to go to the middle setting for the extra inch and I don't think the ride is stiff at all right now on the lowest.

 

I have the 08 4x4 springs with the 5100's set at 1. The ride can be stiff at times, so I can only imagine how much worse it will be when you go with really stiff Pro4x springs.

 

Another one with 08 springs. The ride can be nice on new pavement but bumps/ pot holes can really shake the crap out of it. And anytime the front axle drops, it feels like the truck is following it down vs. the axle bouncing back up. As soon as I can throw the money at it, I'm putting my 04 2wd coils back on with a 1-3/4" spacer. Front shocks are Bilstein HD's and are less than a year old.

 

No, I had to grind the sh!t out of my cb. I dont have a lip where the arms hit. I personally like the ride. It's firm, but its never too rough. I would not go with pro4x coils though; either your current on the second setting or 08+ 4x4 on the bottom.

I also do not run a swaybar, which makes a huge difference.

Running the original Pro4x springs (the stiffer ones) on 5100s. Originally had them on the middle setting. Rode terrible in my opinion. Like a pogo stick. Moved to the lowest setting and the ride is considerably better. To me the added height was not even close to worth the crappy ride.

 

My trucks shakes and judders at every bump in the road, and just with stock front end with 1.5 leveling.

 

The 5100's would solve that. Mine was the same way with the stock Ranchos...

 

i have my bilsteins on the second setting and i don't feel any different

 

I've got bilsteins on the middle setting with 08 4x4 springs and tried to run a 2" NCD spacer. Ground the crap out of my cb and it just wouldn't work so I'm interested in your setup jmoore.

this is exactly the setup that i had... it sucked lol... at first i thought it would be ok, but if you hit a tiny pebel lol it hit hard. i dropped my bills to the lowest setting, and it got a little bit better, but not to my liking. i am currently taking my 08pro 4x coils off. i got a lot of lift out of it, but its not worth the ride. if i had to do it again, i would not do the 08pro 4x coils.


on a side note, not to thread jack, but im debating on going to go with stock coils on middle setting, or 084x4 coils on middle setting.

Go with stock on the middle setting. Even the 08 4x4 coils on the middle are really stiff. 04-07 on the middle will be like 08 4x4 on the bottom, ride and height.

 

I'm 2wd. Would you still think stock coils or go with 04-07 4x4 coils

The Pro4x coils are stiffer, but do add about an inch. I'm sitting at 40.5" up front and in the back. I have my 5100s on lowest setting and guess what, it rides like a truck. I wouldn't have it any other way.

 

I have 08 4x4 springs and 5100's middle setting and the ride is perfect IMO.

 

same here... i hit stuff hard too and am going to RC UCAs and a 2" spacer, going with one of the billet kinds this time cause I bent the crap out of those welded steel ones that are triangle...lol. I cut like 1/2" off the whole outside of my coil bucket already too

 

I agree about having the Bilsteins on the middle setting and a 1.5" spacer (and obviously 08+ 4x4 springs), ride is not rough at all, biggest thing I noticed is if I have to slam on the brakes there is very little, if any at all, nose dive. It is a touch stiffer than stock, but like Tntshaffer says it rides like a truck. My wife even says with my current set up, it rides less like a truck than any of the others that I have owned.

 

Well I reinstalled my bills they were missing a washer. I have them on lowest setting with a 2" space and pro4x coils. Rides great. Not too stiff at all. Little bit of cbc but not bad. Rc ucas can probably fix it.

What does your front fender measure at? I've got the 5100's on top notch and pro4x springs right now. I think I want to change to this set up.

 

I'll have to go out there man look at the tire but I know they are a little bit bigger than 33.
