When do you need a diff drop?

Right now im debating on buying some spcs that were installed them removed for 200$ or some brand new jbas for $600

 

What yall guys think

 

Generally, but not always, JBA is the preferred UCA.
SPC has had issues with bushing failing prematurely. And the ball joints don't seem to hold up as well as JBA.

It's Ford vs Chevy. You have people that like both, and run both.

However, it seems like the JBA hold up better.
It also goes with saying, how you use the truck will play the biggest roll in longevity.
(Fact is, they both are not going to last as long as OE)

If you never wheel the truck, The SPC should be fine.

Then you are on to the task of finding a shop that will take the time to do a CORRECT alignment.
There "can be" (is) more to the alignment procedure than OE.
So here, print this out and hand it to the Alignment Tech and hope he bothers to read the instructions.
