Has anyone installed SPC UCA and still needed to change there stock Lower Control Arms as well?

I was told that the SPC will not work with my current lift system. Its made for a much higher lift that is way its maxed on on camber and no caster.
So i am thinking i need to install a Diff drop, ans sway bar relo. That should give me some camber on drop the LCA a bit.
Whats your thoughts guys? Also, has anyone used the Total Chaos Spindles before?
Will that help as well?

 

First of all your SPC balljoint is installed backwards. Secondly you can have the SPC arms with no lift and have facory alignment specs if you want. Thirdly your alignment tech is an idiot and so is the mechanic that installed the UCAs... the 2 degrees of camber post alignment and the SPC camber adjustment maxed out should have been a hint... Forthly adding caster with the SPC arms moves your wheel back towards the cab mount.

And yes your stock mud flaps wont sork with 285s....

So much misinformation in this thread its not even funny.

 

And a diff drop has nothing to do with anything regarding alignment, or controll arms or clunking.. based on the SPC instal in seems your mechanic cant read instructions and you should have everything else he did checked over by somebody competent.

 

Thanks Swissrally i will look at theae things today and see if the ball joints are in correct orientation and have an "expert" look at them again.

 

Right now your camber is way out at +2 degrees so you will wear out your tires very fast. All you need to do is jack up each front corner, take off the nut on the SPC arm, lift the arm off the balljoint, and turn your balljoint 180 degrees so the flat surface with the SPC logo on it faces out. then reinstall nut, torque to 150 lbs and get another wheel alignment. And bring them the SPC instruction sheet.

 

Do you guys know which orientation is this when i look at the diagram?

 

I almost wonder if your guy didn't put them on the wrong side

 

You want orientation "D" but they are installed backwards. Both balljoints are the same, there it no left or right. The UCA itself looks to be installed correctly. You want the flat part to be facing outwards, not the round part. Turning them around takes 5 minutes per side..

 

Good catch for you guys to see that. Os the instruction i posted on hwre the correct document they can use to realign everything?

 

Yes, looks like the orientation currently on the truck is set to A +2.0 caster.
I can do this change on my own, but i would still need to take for alignment still. I called up the shop and they will fix the issue.

 

You are not set to A. You are backwards from D.

 

ditch the flaps, get a shop that what the hell they are talking about

 

Thanks everyone on your input. Yeah, after looking at the instructions online, its totally whacked out. Appreciate guys.
