Spacer lift interference Question (UCA)

My spacers (2.5") cause the UCA to hit the strut buckets as most of you know. I was going to make/modify a set to clear the bucket.

My Question is if the new UCA don't hit the bucket what will limit the suspension travel from over extending (not wanting to destroy strut seals or brake/ABS lines)?

Do the after market UCA's still hit, but with a bump stop? and if so would they still hit the buckets over every speed bump?

Thanks in advance, OUR collective knowledge is very impressive (by "our" I mean you)

yes, aftermarket ucas will hit if you have the suspension cranked way up. do they hit on evry speed bump like stock? no for the prg's. this topic has been covered several times

PRG's are after market, if you say they do not hit on every bump like stock, how are they doing that, and as to my question what will limit the suspension travel before damage could occur (if any)?

Thanks

the aftermarket UCAs dont hit because of their lower profile design of round bar vs the block styling of the stock UCAs. they do have a bump stop for them so that you don't over-extend your arms and rip out the CV.

So the PRG's for example would allow more travel than the stock ones but they would still be used as the travel limiter?

With aftermarket arms you will not have any coilbucket contact due to their tubular design. The aftermarket uca has a bump stop attached to it so that will be the limiting factor on droop. You will not gain any travel per se as the stock shock is still a stock shock. If you want more travel than an extended coilover is needed.

With the total ciaos UCA's or others if my alignment was just done after the spacers and cam bolts would I need to have the alignment done again or are they the same angles/size?

Thanks

you will need another alignment. anytime you mess with your suspension, you should get an alignment.

When you replace a non-adjustable suspension part (like a ball joint, bushing, our struts) there would be no suspension alignment changes, so my previous question of do the aftermarket UCA's have the same alignment angles/dimensions or are they different, thus needing an alignment still stands.

they are different (much different) and thus need an alignment. and i would still get my alignment checked after anything done to the suspension - even ball joints etc. if you wheel and mess around with your struts, ball joints etc then you need to make friends with an alignment shop asap.

Whether the parts were adjustable or not there is always a chance that an alignment will be needed or should be checked as the parts that are being replaced are usually worn and that always changes things. With the aftermarket UCA you will need an alignment as it a different component!

I second those above. An alignment should be done as the aftermarket arms are build with diffferent angles built in them purposely and factory specs dont apply 100%.
