im looking at possibly buying a lift for my 99 k1500 but I really would much rather go with a steering knuckle lift like I had on my last truck(Chevy Colorado).
The thing is I want only a 4” lift. Is there any out there I haven’t been able to find one.
Thanks in advance
Short answer, no. Lift knuckles/spindles do not exist for GMT400 as they do for GMT800+, there are funky add-on pieces to sort of make a lift knuckles out of the stock unit.
Longer answer, it might be possible: What you would need to do is perform the GMT800 brake upgrade, as discussed here:
https://www.gmt400.com/threads/nbs-front-brake-swap-for-obs-trucks.17805/ and other threads/forums, but instead of milling the BJ tapers out on a stock knuckle it would be on a lift knuckle.
I don't think I've read where anyone has done this, I'm speculating that it is possible based on the reality of making stock GMT800 knuckles fit GMT400s. I have the LCA & diff drop brackets for my flatbed, I need a set of knuckles and something for the torsion bars and I'm game to try it.
