TnT LA install question

Alright so I'm installing the TNT arms. I've removed the axle completely from the vehicle and now it's sitting on jackstands underneath the vehicle (semi lined up). I'm wondering if anybody knows the approximate length the arms should be to bolt onto a 4.5 inch lift so I'm at least in the ballpark. I haven't been able to find any info on this thus far.

You ever decide how to handle this?

If I was doing it and my axle positioning and pinion angle were acceptable on the short arms, I'd install the new crossmember with the LA mounts, set the axle and frame on jackstands with the short arms still hooked up(so that the axle was supported but not bearing the main weight of the vehicle). Then I'd measure from the new LA mounting points to the axle side LCA mounts, set the new long arms to that length, unhook the short LCA's and hook up the long arms. Then measure from the y mounting point to the UCA mount on the Axle, set the upper arm on the LA's to that length, and then unhook the short UCA's and attach the radius arms' upper arms. tweak as needed from there.

Either that, or use stands/straps to set the axle against the bumpstops and get the pinion angle sorted appropriately for fully stuffed, connect the arms and then let it back down to put the springs and such back in. That'd let you center the wheel when stuffed so you don't have fender issues when one side crams up. Then tweak as needed to dial in the angle at ride height.

Those are the options that make sense to me but I'm not sure if they're practical when you're in the middle of it and it would definitely be good to know what you did (or even what lengths you came up with on your setup).

Have you contacted TnT and asked them for some tech assistance?

I adjusted the lowers far enough to retain the 101.5" wheelbase and set the uppers a few degrees forward for slightly less caster angle. TNT recommends about 6.5 degrees IIRC.
