Alignment, Caster, Clearance, and Driving Report with Light Racing UCAs

Based solely on the comment "about 2.75" of lift" - I'd say put them at the -1 setting.

That's where I've got mine.

But you're still going to have to engage your alignment shop in a conversation. See further up the thread for what they need to do.

 

Awesome. Thanks. I'm heading over there after work today to discuss the install with them, then I have all Saturday & Sunday for the install, then alignment scheduled first thing Mon. morning. In your write-up I saw it took you about 7 hours for complete lift install - with my caution and inexperience (and the fact that I'm "fixing" a perfectly good truck) I'm planning on double that

 

Hooked me up with a Christmas special....

 

does anyone know where i can get the paper that shows how to set the adjustment cams to adjust to desired caster? lost mine a long time ago and in need of an alignment bad.

Thanks!

 

Just for making sure I understand this....in the +1*(-1*) reference, this is also known as the "C" position or is it the "E" position. I like the read on getting more clearance in the aft well for 285's and getting those numbers bjmoose achieved. Thanks

 

Reference link in post 258. Setting "E" forces the top of the spindle forward.

 

Lol, typo... Post 253.

 

Thank you guys. I'm dialed in on the "E" (+1) caster setting for more rear clearance.

 

Installed my OME complete kit with LR UCAs a few weeks ago. Don't know too much about alignment but printed out the first page of this thread for the guys at the alignment shop to help them out. Here's what I got.

What do you guys think?

 

3.4 / 3.8 ?

 

This is why I asked, I'm guessing this is bad?

 

That's a fair amount of caster. Some people like that as it makes it "drive like a truck" and track really straight on the highway... As long as your tire clearance at the back of the wheel well and cab mount is good - I'd say you're set.

 

Thanks for the help, so far so good and I've had her stretched out quite a bit, goes down the road straight as an arrow, I will be doing some adjusting when I upgrade to 285's. Thanks again and for the very helpful install thread!

Just got my alignment done.
Caster L 2.0 R 2.5
Camber L 0.0 R 0.0
Toe L 0.00 R 0.00

The truck is pulling pretty good to the right.

Tried to rotate tires with same outcome.
I have complete OME with 885s and top plate spacer. LR's set at D.
Any info would be helpful.

 

I would like to know too, I will be putting this same setup on this sat and having it aligned.

 

I have almost identical alignment numbers as you and my truck pulls slightly to the right as well. I noticed that with larger tires ( I have 285s) that the truck will pull a little bit one way or the other even with a perfect alignment.

 

I also noticed that about the first 1000 miles or so after a tire rotation the pulling starts happening. I drive straight as an arrow until my tires start to pull to the right. I rotated just my front tires to test the theory and it worked for me for a little while until i put some mileage on them and then the truck started pulling to the right again. I think it's just because of the larger mud tires i have on my truck

 

Looking over my alignment sheet again I'm starting to think the problem may be in the rear.
Left Toe 0.60
Right Toe -0.45
That would make the rear track like this / / Right
