It's easy. Takes more time to swap a trans than the rear, IMO

Contemplating the Spohn link kit minus the panhard bar.

It came sooner than expected and has the denali links and sway bars which is kinda nice.

That is a cool piece. So is that a GMT900 SUV rear? Is it 1500 or 2500? I don't think 2500's came with a 4 link but I thought I would ask.

The VIN this came out of is from a 2011 Yukon Denali 1500 with a 6.2, 6l80, and 2wd. Says it had 152k miles 3.42 gears a posi and lived its entire life in south Florida which seems true as there's nearly no rust.

2500s are leaf out back

the "14b" is just a 9.5" SF light duty axle. They are pretty strong, nearly 7k GAWR, and they are of course from the AAM 9.xx family, so bearings, lockers, gears and covers interchange with a whole family of axles; both front and rear. So parts are cheap 👌🏻

It surprised me how limited the gear ratios are. 3.42 is the highest I could get would have probably done 3.08s

yeah, i ran the math on 3.08s a while back... what gets you close to the original nv3500 starting ratios would make for a dog on the highway because 4th & 5th are the same.
granted, depending on whether you're talking blown/cammed 6.0 in a 5000lb truck or cam-only 6.0 in a 6000lb truck, it could make the difference in acceptable loss.

I think 3.08s would be great in this thing because it has pretty high compression and the small cam. 5th would be for cruising only and if I needed to pass someone quickly I could always drop a gear. After driving the silverado last night and seeing how useless 2nd gear is now with much more power it makes me want to go to 3.73s if/when its 10bolt dies. But then again I like how I can start from a stop in 3rd gear in both trucks. Makes it like driving a 3 speed and you hardly have to shift if you don't want to.
