4.11's These possible? Hey all, I just scored a set of gears for my car from a mechanic friend of mine. He said they came off an S10 or something that'd been modded/converted.. and that they would fit my car. I guess what I want to know is, I haven't seen many people with 4.11 ratios. These gears are GM as indicated on them:
-9-37-GM on the pinion. (similar markings on the ring)
Is it just that these are factory gears and aftermarket companies don't make them to fit our 7.5 rears? Or is there a way I can tell specifically if these gears will work with my car? Measurements?
Thanks guys, I just wanna make sure since I'm going to be ordering a TA Girdle, and if I need new gears, I'll order them with it and sell these.
Thanks,
Mat

5000, I get a slight whine around 60-65 mph with street tires all I do is spin, you can only hear it cruising with the windows up and everyone else who rides in the car says they can't hear anything i guess i have sensitive hears, sticky tires and there's no doubt the rear would go boom.My advice if you go to the track and have/ can get traction save up for a 9 inch or 12 bolt.

Before I went nuts on the motor in my car I had 4.10's. With a hooker catback, lid, FTRA, ASP pulley, I ran 12.77 at 111 MPH. The gears helped tons! I ran that time at 2 different tracks and did it on the factory GoodYear F1 tires. On top of that the real reason I would tell anyone to get them is the fun factor goes WAY UP.
By the way those gears from that S10 should work.

Nice... That's where I want to be, I've just got to decide what I want to do in the way of mods to the car. I know next year I want 12's bar none.. but I feel I might even squeak a 12 with nothing done to the car save some sticky tires.. Another problem in my equation is that I want to switch to drag radials on the back of the car next year (since I need 4 new tires anyhow). This presents the problem for me, if I do Nitto's with gears, even with a TA Girdle, I'm looking for some broken teeth, If I leave street tires on, I'm still going to have a hell of a time hooking up, but like you say, that car might be a LOT more fun.. I dunno.. Something I'm going to have to debate.. This is why I'm thinking I might throw on the set of headers and exhaust/cutout. Add 15 to 20 rwhp with my current config and a set of stickies, I should be solid 12.80's anyhow.. Hrmph.. hard to say.Any more opinions?
