# of axle splines in an E-body stocker
 

Time to buy some axles for my challenger. Using an 8.75 housing with 1.75 pinion. Moser has axle and spool packages. Spline choices are 28,30,31, 33, or 35. What number of splines would you choose ? I'm assuming 35 is the standard. Will be running a 383 auto. Thanks

35 spline with gun drilled shafts and 5/8th studs.

I would not put any money in the 8 3/4 rearend, you can not get gears for them, they break. Be money ahead and put a Dana 60 in it.

8 3/4 break. I have been running the same Richmond pro gear in my Dana 60 since 1991. I change oil 2qts. every other year.

35 splines with 5/8 studs with Mark Williams yokes, just bullet proof.

I suggest a Dana 60 35 spline as well for an auto, 40 spline wouldn't hurt if it's a stick. If I didn't have so much 8 3/4 stuff accumulated, I would have put a Dana 60 in my cars. Moser has good, complete assemblies at a reasonable price. You don't have to worry about straightening an old housing or bracing with a new Dana 60.

Ok fellas, I appreciate the replies. I hadn't planned on dumping the 8.75, and don't want to. So maybe to back up a bit, what level of hp are we talking to justify going from an 8.75 to a dana ? auto trans stocker, foot braking. Maybe you can tell me how much hp should I expect from a 383/335 to qualify mid-pack in an E-body ? 450 - 500 ? FYI, it's my first stocker, home built, doing everything possible myself, body is done, just finished with paint. I don't want to shoot myself in the foot with bad decisions, also don't want to buy what I don't need either.

This! I am also building a e body, super stock instead of stock. I would not waste my time with the 8&3/4 when you break one and you will, You will be into the trans & converter also. So money well spent ahead of time. I have a strange s-60 in mine, Do a cost estimate on both of them, The dana is Prob around $1800 You will be into the 8&3/4 for around $800 or so.But the first time you break it you will be upside down in the deal. Big question for the 8&3/4 is what race weight are you going to be?

Listen to this advice!!! He and all the rest above him are trying to save you some money and a lot of hard work... Unless you like repairing broken rear ends, trannys and converters....

It's not a horsepower thing, it's more of a weight issue. The 8 3/4's live well in a-bodies that are under or around 3300 pounds. Once you get over 3500 it's just a matter of time until a cap breaks and wrecks everything else. A big problem at the moment is getting gears lower that 4:56, forget about a set of 5:13's. I bet you can find some good used parts if you look around. Moser, Strange and Mark Williams are all quality pieces.

I hear you guys and don't doubt your expertise. As far as weight goes, with the 383 it looks an F car, and since I haven't done anything special making it lighter, it may be a little heavy and fall into G. And I agree, it will be more stress on it than a A body/340 car. I have a budget and can't afford to make everything bullet proof. I'll start looking around and run some numbers. thanks
