I bet the clutch pack went out and that's why it won't lock.

I'm thinking that's what happened

Unless something has changed a mini spool allows no slip at all. Wouldn’t be very pleasant for a daily driver.

Confusing post when read with the title.  Perhaps this will help. 

 

 

I know how a diff works mines broken I don't want an issue with it not locking rather have it always locked mini spool or full spool

When you have that kind of horsepower you have to control the right foot a little. My supercharged stroked 92 will spin two just as easily as one. The only way I can plant my foot is with slicks on a hot track. Then things start to break. Back in the day you could get big block pony cars with out limited slip. Unless you ordered them with it. Try some sticky tires.

No one makes a spool for the 9.5" 12 bolt.  The only direct bolt in posi other than the G80 is the Yukon Duragrip.  The Trutrac is a 14 bolt part that can be retrofitted to work in a 12 bolt with spacers and I believe you need a new diff cover.

I've been looking for one for my 2018 Custom 4X4 Crew Cab. Every thing I look up on the internet says it won't fit my truck. I haven't even found out what size my rear diff is or the gear ratio. I've heard some say you have to go with 411 gears. Didn't want to do all that, just put in a Truetrac in the rear. Do you know any part numbers for one? 

Thanks!

I put a TruTrac in my old 02 Silverado. 

I was blown away with how well it worked. Just fantastic in every aspect for my needs. 
 

worked much better than the g80 in my 2018

Silverado.
