Eibach 2.0 Pro Kit install

[Black02Silverado]

Finally got around to installing the Eibach 2.0 Pro Kit.  Not a bad install but since I also installed the Trail Boss half shafts and Cognito UCA's it took me 5 hrs.  So far I love it. The ride is so much better and the front end doesn't bottom out going over speed bumps like it did before.  To me it was well worth it and since the shops around here wanted $1,200 to install it, I figured I could save some cash.  I have new wheels for it and getting new Toyo Open Country ATIII's tomorrow.  I got 47k out of the factory Bridgstones. I also installed a 2" block in the back.

I got the new wheels and tires on.  The front is raised an inch and a quarter from stock with the Eibachs installed.  The wheels are  Motiv 427MB Gloss Black w/ Machined Face Accents 18 x9 with a +18 offset and tires are 285/70-18 Toyo Open Country AT III's.  No rubbing at all.  The tires are louder than I expected.  I got the impression they were kind of quiet from all the reading I have been doing online.  Not bad but you can hear them.  

 

Now to give it a bath.  It could use a nice spa day.

Have that kit sitting in bedroom, lol

 

Traded my 1500 in before I got to install it

 

Eibach is down the street from me so I'll swap it for 2500 HD kit

 

My buddy has em on his Toyota and they ride really nice.....

 

Prefer em over the bilsteins I had for sure

Great looking truck and good job doing the install yourself! 

 

I have over 85k miles on my Eibach Po Truck setup and it still feels fantastic so you should get a lot of use out of them.  Again, great job doing the install yourself, its too easy of an install to pay $1200 for somebody else to do it.

It wasn't bad at all.  Only issue was the pouring rain that hit from the hurricane.  Nothing major but still got wet some since i couldn't fit the truck all the way in the garage, plus I like natural light to work with. 

 

On a side note, the next day my thighs were killing me.  I'm not as young as I once was.

Howdy, I just installed the Eibach coilovers and shocks paired with Icon's Delta upper control arms this weekend. I took a peak in the wheel well this evening and realized that the tires are contacting the ball joint of the upper control arms and it's chiseled in a small groove on the sidewall already from the 10-15 miles I've put on since doing the swap. It's doing this on both side of the truck. 

 

My tires are 315/70R-17 which is much wider than the stock 265/70R-17. However I've been running these 315 tires on my truck with the stock UCA's for almost a year now and have had no tire rub. Anyways, I'm headed to the tire shop tomorrow for an alignment and wondering if the alignment will fix this? I know my alignment is way outta wack since the lift & new UCA's so I'm hoping that'll fix the problem. Also hoping I haven't damaged my sidewall with the rubbing, too.

No, an alignment will not fix this. It will not change the spindle to A arm relationship. But some wheel spacers will  

[Black02Silverado]

Yeah, you need a new offset wheel or spacers, which I'm not a fan of.

[Rocky-X]

That is a bummer, but I guess that's what I get for going with a much wider tire. I really did NOT expect new upper control arms to have this effect, in fact I was thinking it would have a bit of the opposite where I would gain a bit more clearance.

 

Just dropped off at the tire shop so I guess I'll wait to get a call back from a tech, but I'm with you @Black02Silverado, I've never used spacers and not a fan based on what I've read about them in the past - and I wasn't looking to replace with different offset wheels either. Guess I'm just bellyaching at this point but appreciate your responses. I'll update on where this ends up. 

 

I guess my next question (because this is the first time I've installed new uppers) - why did the 315 tires NOT rub on the stock UCA when I was running a stock suspension? Thanks.

Update:

 

As @Grumpy Bear and @Black02Silverado said - the alignment did not fix this issue so I now need to find new rims with enough of a negative offset or backspacing to clear the ball joint. Tech also recommended replacing the front two tires from the grooves carved into them which is a bummer - expensive mistake but I'm the only one to blame. Going to call Icon to see what they recommend for wheels as I'm not open to trying wheel spacers. 

[Black02Silverado]

Fortunately that is the only options you have other than finding a narrower tire.  I personally like a narrower/taller tire. Not a fan of the wide. Unfortunately they don't make them narrow and tall, just fat.

 

I also went with Cognito UCA's because they looked to be the least of the bunch for interference. I'm running the factor ZR2 wheels now with 285/70-18 Toyo Open Country AT III's I have a 1/2" between the UCA and the tire.

Different geometry. Your new arms move the location of the upper joint so that when lifted it doesn't stress the joint to failure.

Update:

 

Ordered new rims and got 'em installed today - they're Pro Comp 32's (17x9) with 4.75" backspacing & -6mm offset. They poke out of the wheel wells quite a bit so I'll be chipping paint on the rockers in the future but hey - they now clear the control arms! I have some plastic to trim behind the wheel well fabric, the tires start rubbing around 3/4 full lock - yeesh.

 

Hey thanks again for you guy's input.  I put 200 miles on my bicycle commuting this week while the truck sat - self punishment for being a dumbass.  Here's some pics:

Doesn't stick out too far. Looks good.

[ocbasbalburg]

OP, Do you have the part numbers for the Cognito UCAs and Trail Boss half shafts (CV Axle I assume) that you installed? 

 

Did you need to replace the UCAs or just did it to prevent future problems? 

 

I had the Eibach 2.0 Pro Kit installed on my 23 RST about a year and 3 months ago and I am getting a clicking sound that the dealership communicated was from the CV Axles.
