    Going to install SPC UCAs this weekend and was hoping to not need an alignment right away, because life...

    Instructions tell me what setting to use to keep factory caster, but what about camber? I have factory UCAs right now with a decent alignment.

    Anybody have experience with this?

    I've installed a few SPC's. Camber must be set manually. The adjustment bolt should be set outward almost all the way. Instructions say to start at the center, but so far that has resulted in lots of negative camber.

    After making camber adjustments, need to take the truck for a short drive. Either down the block, around the block, or up and down the driveway a few times. Then come back and check camber again. This allows the suspension to settle.

    You will need a toe alignment as well. The longer the alignment is out, the faster your tires will be wearing at an accelerated rate.

    Just completed the install. That was much easier than expected. Used the device that @Shavenyak suggested and your alignment advice.
    Toe was out quite a bit after install. Was an inch difference between the front and the back of the wheels.
    I feel confident that I got the alignment pretty good, so I can schedule a proper alignment within a few weeks.

    Would a chalk test help confirm your confidence?

    That would be a good idea regardless. Still need to figure out what the proper pressure is for these tires anyways.

    Ha! Just got it back from the shop today. I was only off 0.06 degrees on the driver side toe, rest was pretty much spot on!

    Caster is at 4.

    Not bad for a driveway alignment.

    impressive, good info in this thread. I have spc's and once I go up to 35s will need to do some adjusting myself.
