spacer lift and 5100???

OK i am a little slow and my mind is numb from reading. so here is my question.
i put a 3" (tuff coutry) spacer lift with AAL on my 2010 DCLB. would i gain anything by also changing the shocks to the 5100??? would that be a waste of money?? also with the spacer lift do i need to worry about the uca??? should i have changed that out also?????
i am confused by it all. is there any problems with the stock drive line with the AAL????
here is a link to the lift i have.

thanks for the help

 

Not worth it you are already limiting your coil travel with the spacer, if you put 5100's on and set them to a higher setting it would be a horrible ride

 

If you get the 5100's you would be better off ditching the spacers and setting the billys to 2.5". That's a much higher quality lift than the spacers.

 

would i need to change the UCA? what else would be involved with using the 5100 over the spacer. should i have changed the UCA with the spacer lift?

 

You only need to change the UCA if the shop can't get your alignment right. The new UCA puts the geometry closer to stock.
