I think I've found a 4.10 center section. I'm going to go get it on Sunday. What should I look for before I hand over the money? I'll make sure the pattern looks correct and that it all turns smoothly and the splines are good. The guy also says it has limited slip, but I don't believe any stock 28 spline setup has limited slip. Can I tell just by looking at it what type of differential it is?

They were available in 28 spline. Check out this site for Id tips: http://www.kevinstang.com/Ninecase.htm Hope this helps. Chuck

Charlie. For a limited slip carrier, look for 5/8” headed ring gear bolts and those bolt heads will be countersunk somewhat into the outer cover. Single track carriers typically have ¾” headed bolts while the bolt heads themselves sit above the carrier cover (no counter-sinking). Also look for a double row of splines within one side of the ring gear carrier where the axles fit.

Thanks. That helps. Is the ratio stamped on the ring gear?

Charlie: I can't believe YOU'RE asking questions!!! You normally have all the answers...LOL The ring gear may not be stamped 4:10 but it will usually have the pinion & ring gear #'s Like 41:10 or?......Trying to lower that E.T. huh? See Ya, Bill

Haha. I'm just a grasshopper and have lots to learn. I know pretty much nothing about rear ends. I'm actually hoping the 4.10 will increase mileage and make it a little more user friendly in crawling or stop and go traffic since the engine has noticeably less torque below about 1500rpm but I am going to take it to Atlanta Dragway to see how it changes things. So the first round of gear testing will be for street manners. When that is figured out, I'll work on strip gearing. I don't really need the limited slip now but it will be good to have if it is in fact equipped. I just need something that moves the truck forward and backward for testing, for now. That is good. A stamped ratio will be much easier than counting teeth.

Charlie, Just one year older and you are getting foggy already? Did you check the site on 9" rears? It's very informative althoug some of the pictures seem to have fallen off. Chuck

I did take a look at the site. What do you mean? Foggy about what?

Alright. I got it. This one is a learning experience. The ratio is not stamped on the gear, rather a part number and that number is 4210. You have to count the teeth. It is 39/13 or 3.00 ratio. It does appear to be in good shape, so if anything, I have a 3rd member that I can swap a R&P to. It is an open differential, too, not limited slip. Oh, and if you buy reams of paper by the case, the cardboard box they come in is a perfect size for a 9" center section. Very light duty but great for a short trip.
