SierraZ714x4

yes i have received and installed them. 100% legit from a verified seller on ebay with 100% feedback so i trusted it. the lowest price i have seen by it now is around 1200 so i got extremely lucky with the no reserve auction.

Just won a set of AMP steps with plug and play off ebay for $560...... lucky day

i had a 2011 sierra CC with a 4 inch BDS and loved it for the time i had it but really did not want that big of a lifted truck again. On my 16, I originally had a RC level but had nightmare after nightmare with my stock tires rubbing the UCA. So i ended up going with Fox 2.5 Coilovers and Cognito UCA and it fixed all my problems and it rides like a dream on and off road.

but if you do go airborne frequently please post vids

theres honestly not really even a comparison. i felt a big difference after adding the fox 2.0's in the rear while i was still stock in the front. then, after adding the 2.5 non resis, it was like a whole new truck. off road it is not even in the same ball park as it was stock and in the city it's a little stiffer but it still rides a hell of a lot better. i would spend the money again no doubt about it! hope that helps.

here is mine with the fox 2.5's, cognito UCA, and 275/65 KO2's. everything fits great with absolutely no rubbing anywhere (did not have to trim). AMPs and tint and i will call it a day with this one!

Yes, I've been meaning to post some i just haven't gotten around to getting some good ones. No, we did not cut the bump stops but i haven't really gotten it off road yet so i may cut them when hunting season comes around and i really get to try these things out.

I'm running the fox 2.5's with cognito UCA on stock 20's now with 275/65/20's and it looks awesome. Definitely recommend the 65's over the 60's hands down.

I'm running fox 2.5's with the cognitos on my OEM 20's. 275/65/20's going on thursday

not that I've seen on the forums. heres my thread http://www.gm-trucks.com/forums/topic/198451-stock-wheels-and-tires-rubbing-uca-with-leveling-kit/

most people that I've seen (assuming you have stamped steel UCA) run 2.5 with 275/65/20 with no problems but i haven't seen anyone running 305's without wheel spacers

yeah I've never run fox coil overs before so i am pretty excited about. as far as your leveling kit goes, my dealer told me the other day they run the 2.5 RC kits on all their trucks that they level with zero scrubbing issues. so I'm not sure if my issues were install related or what but i couldn't turn going forwards or backwards lock to lock without destroying my UCA

I had the same exact problem. i made a thread about it a while back. i have ordered fox 2.5 coil overs and cognito UCA to replace the stock components that will hopefully be going on within the next two weeks.

I asked the dealer about this when i bought my truck and he almost laughed at me and said AMPs would be wayyyy cheaper and much less of a headache. Just my .02

sounds like I'm going to have to bite the bullet on 1/4 wheel spacers which i definitely don't want to do.
