Lowering a 4x4

[Supercharged111]

Cool guys, but this is a GMT400 forum and they didn't get factory blocks.

Just like some said earlier, use 1999-06 dropped spindles which allow you to run the bigger NBS brakes. You have to ream out for the upper and lower ball joints. There is a thread on this forum about it. Then you can use the Atomic Fab coil overs and ditch the torsion bars to achieve your desired height.

I lowered my 4x4 Tahoe with belltech keys and spindles I used moog problem solver Upper CA with 4* and belltech shocks on 20’s rides descent. I think I’m gonna try different shocks one day

Yes, that is what i'm doing. Got spindles from a 06 gmt800(or lowered spindles). Lower control arm from a 2000 2500, you have to ream out the upper ball joint in the spindle to fit the stock upper control arm of the GMT 400 truck. The lower control arm will fit no mounting mods. Then you just have to run the GMT800 brakes. The GMT400 axles will work if you discard the thin metal ring that is closes to the spindle. Or use the GMT800 axles if you have them too.

So the gmt800 lca fits the factory gmt400 lca mounting location? Does it keep the same track width? Do you know if the uppers are compatible?

A 2000 2500 is still a GMT400.

I didn't know that

Could be a GMT800 also.
