Gear ratio

[davidh]

Clutch packs inside the differential create additional resistance. This resistance is always present. It is called preload. So, whenever one side wants to start rotating faster than the other, this resistance (preload), in addition to the traction present at the wheel has to be overcome before a tire can spin.
Traction and preload have to be high enough to keep tires from spinning but low enough to still allow tires to rotate at different speeds in a turn. Since the preload has to be kept low enough to allow safe cornering the slowing effect on wheels that want to spin is marginal. It works in easy off-road conditions and on mildly slippery roads. For serious off-road use and very slippery roads (snow, ice) limited slip is not powerful enough.

Remember, it limits slip but it does not prevent it completely. Only a differential lock can do that.

Look in your glove box.
GT4 equals 3.73
GT5 equals 4.10

You will probably find you have a GT4. If you have a GT5, you must be living right. Praise the Lord.

Double D I got that info off a site, but to make it simple limited slip allows the inside drive wheel to slow down when making a corner while the outside wheel will turn faster, this makes less bind on the carrior in the rear end.

I will look at all those numbers again and see what I can find. Thanks for your help!

Whew. I was a bit lost on the first one. Makes sense. Thanks again!

Thanks, Basecamp. Will check again!

Hey, everyone! It's a GT4! 3.73... Thanks all!
