when i had my exhaust replaced, i noticed that we have a 8" differential. obviously, 8.8" gears will not work. lincoln has 3 sizes...none are cheap. i was looking at my summit catalog and came across 8" ford gears. would these work or not? gears (http://www.richmondgear.com/01pdfs/page5.pdf). doesn't say by application, but 8" is 8", right!

hmm, seem to stumped you guys. what do i win?

The only gears available are 3.31 and 3.58. Are you looking at 3.73's or something?

Read this thread: LS Gear Swap (http://www.lincolnvscadillac.com/showthread.php?t=11970)

i'm somewhat happy with my 3.31's. i was just trying to help others out. my link shows several different gears for an 8" unit, including 3.80, 4.11, and 4.62. just wasn't sure if there is a difference in ford 8" diffs. i work at ford, so i know there are only 3 "oem" gear ratios. i read that thread already. sounds like he is very happy!

Does anyone have the specs on the LS diff, besides the obvious? I would be very interested in a real low set of gears.

Those WILL NOT fit. Not even close.

By the way, there is a complete IRS on eBay for $200. It claims to be out of a 2003. I believe that's 3.58's, right? Regardless...that's cheap for a set of gears already in a pumpkin. Someone should jump on that.

I agree with ya 2001LS8, but the only problem is shipping. I have another 3.58 pumpkin I bought as a spare and it cost me $100 just to truck freight it from Ohio to Illinois. I cant imagine what the whole rear assembly would cost to ship. If you guys need help finding 3.58 pumpkins, I have a good source. I can get most at $350-400 to your door. Its the shipping that kills you on these. The pumpkin is pretty heavy.
