alignment after lift

I know that this topic has been discussed quite a bit lately, but its all in passing, so I wanted to ask a straight forward question...

Once I put my lift on, what kind of alignment will I need, AND WHY? If I put 4" longer springs on, 4" longer r-arm brackets, 4" longer ttb drop brackets, 4" longer pitman arm, then what else is there to screw up the alignment? I've heard by several people that I definately will need an alignment after a lift, and I don't doubt it, but I just don't see what changes affect the current alignment. Thanks in advance!

Re: alignment after lift

The new parts do not keep the same relational mounting distances as the stock parts, though in theory your idea is correct. If you were spacing everything exactly 4" from it's current point, alignment would be unaffected. Not the case, so alignment is mandatory.

Coils are probably the biggest variant in the equation, as they do settle over time and differently in every application.

Re: alignment after lift

Your toe will likely not be correct. You may also notice that the top of the front tires stick out a bit.

Looking from the front, they would look like this: \ /

That's + camber, and will need to be corrected.

Everything may say for a 4" lift, but the reality is that alignment deals in 1/32nd's, .03", 1degree, in other words, very small increments. It does not take much for it to be off a bit.

Re: alignment after lift

Thanks for the clarification. So what you're saying is that I should go and get my camber re-aligned, and if I notice it pulling I should also get my toe in checked. Again, thanks!

Re: alignment after lift

I'd suggest getting the ADJUSTABLE camber/caster bushings from NAPA. I aligned my own, several times now as the springs settled and I lengthened the radius arms. They are pricey, but will allow you to make changes over time without spending more.

Re: alignment after lift

I know nothing about how to align the camber, do you have to get different bushing everytime or what?

Re: alignment after lift

There are different types of bushings. The stock bushings go in one position only and adjust camber only. The adjustable caster/camber ones can be placed in several positions to adjust caster/camber and have a seperate adjustment for caster. They may be overkill (price) for your situation.
I learned, through trial and error with the adjustable bushings to do my own alignment. I used a tape measure for tow-in and a level for caster/camber. Some places will give you a lifetime warrnaty on alignment, but I don't know if that includes parts (bushings) if you needed to make changes. Check and see how much the regular bushings are and how the warranty works.

Re: Adjustable Bushings

Here's the post with the Ingall's (at NAPA) part numbers.

This is what they look like, and where they go.
