I have run a Tru Trac for many miles, both street & track. On a road course when they start to wear out the unloaded side will spin and lose traction. Coming right off a road course to the drag strip the wore out Tru Trac still hooked both rears. They will fail first in a auto cross / road race envrinoment before the drag strip.
Do not use synthetic gear oil, dino oil only.
Street manners are way better than a Detroit Locker.
The Tru Trac is not rebuilable.
I am currently running a HD wave trac for the first time. So far I like it, but only has about 2K miles on it and maybe 20 race miles.
I went from a Trac Lok to a DL to a Tru Trac to a Wave Trac. The DL by far had the worst street manners...

Hope this helps make a decision.
