I'm so glad that the search is over! I was wondering if you were going to get them both!
Me also, I owe you guys one. Welcome to come up for Trout or swift water Smallmouth fishing, whitewater rafting, Appalachian Trail, golf at the Greenbrier, or ______(whatever) anytime.

Honestly was going to wait and get it later.....then thought about the front and rear 3.08 set I can sell + the extra 3.08 front diff(with missing passenger side tube I can return($300) and made myself do it so I could get through the buyers remorse stage as quickly as poss and enjoy what I bought... Plus Summit beat the $686 price I found it for on some site I'd never heard of. Still a lot to buy though.... coil springs, bump stops, HP Tuner MPVI interface, POR 15, Amsoil, bar style in lb torque wrench, new perf leather seat cover, sunroof track cable......then immediately into the Torque Converter job....kitchen stuff....smh. Here comes the anxiety again :oops:

I hope your wife understands the significance of bringing home this kind of rear end instead of another!
HAhaahhaha... Thankfully, that's her kind of humor because she called about a minute after I typed that....had to read it to her ;)

Kinda banking on making sure there's visible progress being made in our kitchen everyday. That's my best chance of maintaining my current residency in the house

Sounds like my house, at times the money flows out faster than it comes in!

This the front diff you got the Cognito spacers for? I went back and Re-read that thread this morning. When I read it the other day I didn't catch that it was 2010+ 2500...

yea silverado/sierra 2500/3500,
spline - inside the diff i think are 33? but doesnt really matter youre connecting to the 8 bolt axle stubs.
the 8bolt complete cv axles are 36 spline iirc. cant use them on 1500s or pre-2010 2500s, however gmt900 and pre2010s are same size and both 33 spline at the wheel hubs....

Sup bro....Hope all is well in Fla! You still runnin those Cognito CV axle spacers? Any issues?

Been tryin to think of ways I could raise my truck game up nearer to the level of yours :D and have decided go Long Travel front suspension, w/DIY LCA's (cause you know I'm not paying desert racing fab shop prices...smh)

Working out the axle math currently. Tryin decide between goin with some extended travel 8-ball increased angle CV axle assemblies? -or- ordering some longer axle shafts? -or- cutting and sleeve welding my shafts? -or- a set of spacers?? All those last three options will likely get a little modification to my inner CV housings also?

Watched a really interesting vid, of a young man, taking a Dremel to the 90* edge on the inside lip of his inner, sliding tri-pod, housings. Dramatically increased his inner CV joint articulation angle at full droop.... Did it in 10-15min per side too, just by grinding that 90* inside corner of the outer end (directly under/inside the boot clamp), the inside corner that the axle shaft would be resting on when at full droop. 90* down to around 35-40*.....pretty impressive piece of ingenuity IMHO
