Default Do UCAs affect on-road handling?

Howdy Folks,

I just pulled the trigger on some Icon Delta Joint UCAs for my truck this morning, and while I wait for them to arrive, I've been scouring the internet for reviews of the same setup.

Most everything I've read indicates you'll see an increase of 1-3" in drop travel, and you should see increased reliability using a joint that allows for more articulation.

That said, I was curious if folks who have installed UCAs after doing a coilover level saw any improvement in performance during their everyday driving conditions?

Also, if I'm having these done at a shop, do you think it's worth replacing the LCAs too, if only to have a completely fresh front end?

The truck has ~44k on it.

Thanks,
Mike

It should only affect daily driving if the stock UCA wasnt allowing the truck to be in proper alignment. I had to get UCA's on my Jeep because the stock UCAs were not the right length once the suspension was sitting higher and the bolts on the LCA's could not be adjusted far enough to bring it back into spec.

If the stock UCA does allow proper alignment then I cannot see an aftermarket UCA changing much of anything.

You'll pick up about 1.5" of droop and as posted above, you won't notice a difference unless there was something wrong with the outgoing set.

no need to replace the LCAs unless something is wrong with them.

I don't know that anything is necessarily out of spec, but I've been on the Fox 2.0 coilovers for about three years now, and the truck doesn't seem to track as well as it used to.

I'm not seeing any tire wear, but I was halfway hopeful the new joint, along with bushings where it connects to the shock tower would help tighten things up.

Regarding the LCAs, I was just doing that as a matter of best practice. I've never owned an F150 before, but my previous Super Duty's ate ball joints constantly. I figured if the original ball joints had 44k on them, it might be wise to replace them now for the ~$200 parts cost, vs. having to pay labor again in the near future.

If the lower ball joints on the F150s seem to last, then I guess that's not a concern.
