Intro to fitting 35s (< 3" Lifts for those that wheel and love alignments)

When you are turned full lock, how far is your tire from the arm on the upper? With the 1" spacer I'm 1/2" from the upper on full lock (pic below with 1/2" piece of plywood)
You can see the smudge where the tire hit the control arm without the spacer.

 

I don't think anyone answered this. Low caster causes tracking on the highway. For example, if you are travelling parallel to an uneven line on the freeway, when your tire hits it, the truck will get pulled to where the line goes. It's very annoying. I experienced this when I first lifted my truck and still had the stock UCAs. Anything below 3 and the truck feels squirrely and unpredictable on the highway. I can't even imagine a 1 or 2 dgree castor with swaybar delete, that would scary. (not saying you're doing that, just a PSA)

 

I didn't get measurements and the pics aren't the greatest.. was holding the steering wheel at lock and trying to snag pics at the same time.. I've easily got 1" of clearance at the UCA. Don't mind that rub mark on the uniball cup.. I got into an accident a while back and the tire blew out and rubbed on the upper.





This last pic isn't at full lock.

 

I really appreciate all your help. Unfortunately it's the front arm of the UCA that I'm concerned about. I clear the ball joint area. My tire hits the front arm of the upper before full lock when not using the spacers. The trick to checking at full lock is to turn the wheel all the way and then turn the truck off. The wheel will stay at full lock that way.

 

ahhh I thought you meant at the cup. I'll get some other pics in a sec..

 

Full lock



Thumb for reference... Lol

 

Awesome, thanks, that helps a lot. My tires will be about 3/8" closer but it looks like it'll be fine.

 

Thanks luckily I live in Colorado where we have no lines just massive potholes and things of the like. Lol

I haven’t noticed anything of the sort so far but will be trying a different shop once I decide I need another alignment since maybe I don’t know how it could feel better. I plan to remove the sway bar eventually for summers only but have left it so far. Maybe I should until I get a better caster setting

 

Good thing you haven't experienced any issues. One way to think of what's happening is to picture a shopping cart. They have 0 caster. I'm sure you've pushed a shopping cart and had the front wheels shimmy back and forth for no reason. Granted because there are no other suspension parts you would need to add negative caster to a shopping cart but it would stop that from happening. Also the head tube angle on a bike. They are never perpendicular to the ground because you'd kill yourself on a bike like that, they always have a forward rack or positive caster.
Good luck with your alignments and I highly recommend keeping the sway bar until you get it sorted out. There was a great place in Pagosa Springs for alignments years ago but I doubt you want to drive 5hrs for one, if it's even there still.

 

Replace that with 37s

 

I adjust mine on vehicle in maybe 5 minutes per side. Loosen jam nut for the heim, pull the uca bolt, and lean the Uca out a bit and spin the heims and then bolt it back up. Do it without removing anything else

 

Anyone running DK tubular UCA with 35s? I have a cmr, pinch weld cut/hammered and fender liners cut up. Looking to avoid cutting fenders/flares but will if I have to. Also, wheels are 17x8.5 -25 offset

 

Thank you for this OP thinking of going bigger on my truck and didn’t know how much a pain it would be

 

Relocated spare tire hoist for more clearance. My 35 10.5 r17 was rubbing my diff

 

It takes me longer to shine my tires than to wash the entire truck

 

It will make its way back to its old home if you ever do hangers. Diff rub is a way of life. Lol

 

damn I thought I did some good lol

 

why is it that hangers allow it to slide forward? Do they allow more clearance as far as the space from hanger to other hanger?

I’m probably going to go with DRT fabrication hangers

 

The hangers are just a little tighter and since the tire is a circle, it moves forward where it was before relocating the spare tire hanger.
