This is probably a bit of overkill for the thread topic, but I'll provide this for those looking at narrowing 12-bolts, etc. I'm not sure what you can do with your 10-bolt - is there a Locker available for it ? If so, you may be able to do pretty much what I did here. If you're interested, I can provide you with the Visio file I used to produce these drawings, etc. All this stuff is drawn to scale, so it'd be pretty simple to adjust the design drawing to fit your housing width / flange needs, etc. If you don't have Visio and would like a custom drawing, contact me and I could perhaps modify the drawing to fit your widths and provide you with a design doc for use by the folks doing the narrowing. This may be old hat and a lot of overkill for those of you who've narrowed a thousand rear-ends. I'm obviously not one of those.BILTIT wrote:I have been looking at this option aswell. I currently run moser 28spl c-clip axles for some added strength over stock as i have added nitrous. I am going to be narrowing the rear this winter and want to upgrade axles. The only way i can get any decent axle spline in a 8.5 10b is to go with the 33 (highest spline option) and a spool. I do not know if i will like this as it sees alot of street time. I figure 33 splines are overkill for me and thought that gun drilled and star flanged would be plenty strong yet lighter.
I may have to look into Strange or MKW options though.
I was looking to upgrade rears but i am confident the 8.5'' will hold up to my peezly low 11 times and will be much cheaper.
You could maybe do this same thing and use a spool, but I cringe at the thought running a spool on the street with all this rubber on the road. Big block Chevy, manual steering, monster rear rubber with a full spool. I'm not man enough to drive *that* combo everyday on the street
On the Camaro I went with 33 spline axles because they were the toughest I could get for my standard GM 12-Bolt housing and new Detroit Locker, and with Moser cuz they seemed to offer suitable hardware for a good price. Beyond that, as I recall, there is an aftermarket 12-bolt housing available which allows you to run the heavier carrier along with the stouter 35 spline axles. For me, that would have been a bit of overkill, at least in terms of what I want to do with the Camaro. Attached is a design doc I put together for the shop I engaged to revamp my 12-bolt housing - I went with Pontiac/Olds housing ends, replacing my original small GM housing ends (which also used c-clip eliminators) and had the shop install the new Locker and order my axles. After I got it back home I added the Aerospace Components disc brakes, etc. It turned out pretty well though it took a chunk of change to get the work done and all the new parts ordered. I ended up powder coating, etc., a cost and bother you might not need to fool with. Below the drawing is a shot of the finished rear-end just prior to installation.
