What is the best performance diff to run?
 

My current OEM diff is in need of a freshing, I use the truck as a fun toy, not as a DD. I do use it to buzz around town and do normal things with. But Since the diff in the truck has lost the limited slip and I am waiting to also install gears. I wanted to grab some opnions on what is one of the best performance diff's to run. I am new to the truck thing, but have had multiple other cars.

I was looking at running 3.73's gears.

I was looking at the following diffs.
Eaton 19559-010 Eaton Posi Differentials - Free Shipping on All Orders @ JEGS
Auburn Gear 542052 Auburn Gear Pro Series Differentials - Free Shipping on All Orders @ JEGS

Eaton clutch type. Tru-track can stay on the shelf in my camp.

19559-010 is the ticket. I run an auburn and haven't had a single hiccup with it but I don't know how it will handle 800hp. I'm at about 600rwhp right now

Good Info guys, I guess its Auburn then, anything special I need to know about them? specific gear oil they like to run? specific bearings i need to order with the diff?

If you drag race and do burnouts with water, that auburn could have a short life. Been there, done that. It's nice on the street though.

What are you suggestions then, I am open to any diff. I want a "serious" diff I can do 60 ft burn out withs down my driveway. And be able to abuse it with little to no concern.

I have put 2 eaton diff's in mustangs I have built and they are 800hp plus and took the absue for 5 years and then needed rebuilt, but I want a serious posi or locker that can take punishment.

Just was reading your signature, caught my eye. do you have a build thread or maybe a web page or site about your truck. it peaks my interest! :devil:

Yea, I have 2. Search my name in the projects section.

I like eatons with upgraded springs.

Is there a possibility you could link me to what diff you are referring to? I am not familiar, and I dont want to order the wrong one. Thanks
