Cross referencing this here...

Figured I would post my links to 8.8 tech i have aquired, never made my own because these were more then sufficient. If people search I hope this will come up for them.

at a glance...

These are the codes you will need when out shopping for your 8.8

Axle tag codes:

3L73 = 3.73 LS

4 10 = 4.10 open

4L10 = 4.10 LS

and so on

Door codes:

43 Open 3200 3.08

41 Open 3200 3.27

42 Open 4.10

46 Open 3.73

45 Open 3200 3.55

D4 Limited Slip 3200 3.73

D2 Limited Slip 4.10

L73 Limited Slip 3.73

Here's all the specs, measurements, and misc crap about the 8.8 you'll ever want to know.

another word on the u-joint flange, the one off an early 90s explorer will work for the 1310 ujoint, it has a spicer p/n 2-2-671, I was unable to look up that number, but it did work.

I've got a quick question. Can I get a ring and pinion set of 5.38 gears for an 8.8? I can't seem to find them it goes from 5.13 to 5.71? I'd like to put a dana 44 up front and regear to 5.38s so I'm hoping someone can help me find gears for the 8.8. thanks
