Could someone please explain what a goldtrack rearend is, & what affect it would have,(if any), on the handling of a modified. I overheard someone talking about a mod running one, & don't understand their concern. Thanks

the gold trac is a limited slip differential that is purpose built for dirt ovals (they may have more than just dirt systems but thats what we are talking about here)It allows the car to turn easier without breaking loose the rear tires. They are ILLEGAL in IMCA. I don't know about UMP maybe someone could answer that if you run UMP.

Traction control , limited slip basicly , you won`t see wheel spin with a car that runs one , just bad fast .

basically a car that is bad fast and doesn't slide through the turns. Or doesn't slide much.

If your teching it, jack up the rear end and try to hold one tire while turning the other, if you can turn one without turning the other, then something is wrong, not neccesarily a gold trac, because a broke axle will do that and open carriers will also (don't know why anyone would run an open carrier) But that will give you an idea, then you can tear it down to find out for sure

Can't you mark both back tires in the same place and see if they line up after driving it or am I wrong? I've see them do this and I thought that is what they were checking. Please correct me if I'm wrong.

I have a goldtrack, and yes the mark on each rear tire is the way to go. Flyinlo, I cant turn one wheel with my hands, and the other stay still. I ran this on pavement in a prostock, and it did make it fast. I have it for sale by the way, if anyone can run it, and is interested.

so you can't do that..... hummm. I figured it would be like a regular limited slip deal where one would turn and the other wouldn't.

Then I guess the best way would be marking the tires.
Sorry for the mis-information, my bad LOL!

We used to run one in the late model & if both tires turned together it was time for a rebuild. I don't see how marking the tires would tell anything..the smaller tire is gonna turn more than the larger tire so your marks won't line up anyway.

What is your gold track setup for? A 9in ford? How much?

I hope thats tongue in cheek because your nuts if its not.

Gold tracs were not intially designed for dirt tracks. Its a worm gear limited slip type differential. The problem with them is that they are preload dependant and with such limited traction on dirt they are very sensitive to preload. When we were running them 6-7 years ago we had to reset the preload every couple nights to maintain any kind of consistancy and longevity. If you let them get too loose for too long they will wear out very quickly. IMO you are better off buying an aluminum spool, the tradeoff in rotating/unsprung weight is not worth it for the gold track, they just don't work that well on dirt.

i ran true track for a while...it is the same as a goldtrack, just less money..what a piece of junk. i never had my car work so inconsistant, it would take off towards the wall out of turn 4 every so often. and this with leafs. i got rid of it years ago and now run a mega light full spool, much better.

I always checked by watching if a tire "jumped" while pulling into/out of your parking spot in the pits. If the rear isn't locked, you won't see a tire "jumping" while the front wheels are cut hard.
