Adding 5100 in front with spacer

[cajunduck1]

I have a 2019 RST Z71 with a 2" rear block and 2" front spacer. I already added 5100s to the rear and will be adding them to the front. Would it be possible to set the front an inch higher with strut and be ok? And I would add a 3" block to the rear to keep it level.

I thought 5100 rears were good for up to 1" of lift...+3" might be stretching it.

It's gonna be REALLY hard to get the front end back together like that, if not impossible. Your ball joints are going to have some really bad angles. 2" is all I would lift with factory control arms.

3.5" total (2" Lift and 1.5" spacer) is the highest you want to go over stock in the front for NON Trailboss/AT4 before upgrading UCA's. 

 

For TB and AT4, 1.5" (spacer)is the highest you want to go in the front before upgrading UCA's.

 

Going higher without replacing UCA's will generally result on a short life span for your factory UCA's.  Once you go 4"+, your usually looking at UCA's and differential drops to keep your CV angles in check.
