The LSD is not the weak point in the diff...

 

thanks, this is what i was getting at. so what exactly is the weak point in the diff? i don't know what's wrong with my diff right now. i need to let someone who knows their stuff listen to it. i might be able to get a vid.

 

i believe its the casing. The pinion gear gettin pushed out the back of the casing and cracking with high hp applications.

 

From what I've seen, the gear teeth break off along with other mechanical parts inside the differential.

 

okay so wat would u have to get for ur rear end to be safe?

 

As previously mentioned in this thread...

upgraded axles / driveshaft
puddymod differential / InlinePRO R200 Diff kit

 

i'm running hte Chrysler 8.75" rear by Kasper Fabrications w/ Driveshop shop 1000hp axles and prop shaft.

Broke rear in for a while. After installing linelock, did my first hole shot first and second gear. After that, my tranny blew.

 

wow that sucks, your still with the 3mm headgasket aren't you? how much power your putting down?

 

still on the 3mm gasket making 520.

Have a built engine by Inlinepro whih I plan on making 600 +.
But the trans is concerning me. Not going to put the car back on road and blow the trans the same day so gonna chill for a while and see what other options there are.

 

There is always going to be a week link in the drive train. My out look on it is make it cheep, easy to get to, and easy to fix. The stock axles are very good and will take a good amount of demand before a failure. You can replace one pretty easy and pick one up for around $200 bucks.

Sorry to here you have a very expensive and hard to replace transmission. I here there is a company in Australia making a transmission for our car that will handle pretty much anything for $7,000

Good luck
