Question C-clip eliminators...Any negative side effects?

I'll be building a rear end for my car soon, including an Eaton or FMS 31 spline posi, 31 spline axles, and 4.10s. My car sees street and plenty of strip use (on DR's). I'm also going to start auto-x'ing as soon as I get my rear done (reason for not buying a locker and running 'big boy' tires).

Should I buy C-clip eliminators to install also? If I should buy C-clip elims, are there any side effects that come with the elims? Will I still be able to tAkE Da TwIStiez, y0, or are these designed for drag only use?

Thanks corral,
-Patrick

From what I've been told C clip eliminators are not meant for road race duty. This is from Rob Moser at Moser Engineering. Basically the bearings used in the eliminators don't like side loads like from taking hard corners and will eventually fail. The alternative I've been told is having 9" housing ends welded onto an 8.8 would be able to handle the side load and would allow you to elminate the c clips in the differential.

As far as what I've heard, if you use the 9" housing ends it is the perfect solution except you loose your rear ABS, since the ABS exciter-thingy-of-a-ma-bobs don't fit on.

Yep, c-clip eliminators will leak if used on the street.

You could probably come up with some other way to make the ABS work with 9" ends.

Not true. If they are sealed properly they will not leak. I went through the issues of leakage on the street because I drive my car every day. Initial leaking was due to the shop doing a poor job using silicone on the passenger side. This was easily fixed. Then the other leak that I encountered was through the bearing itself. After some research I found out that if you use a 87-93 type rear end seal, notch it and press it into the house this will fix all leaking problems.

Since installing the seals on my car the rear end has been completely dry. I've put 8K miles on the car including a 1300 mile trip to and from Georiga and a trip from Texas to Florida as well.

The problem with the C clip elminators in road racing is the side load on the bearing. The bearing can't handle the side load and will cause failures. The 9" housing bearings can handle the side load that is why they are better. Adding 9" housing ends isn't exactly a simple job. The rear end has to be pulled and put in a jig to keep the rear end straight while putting the new ends on.

Thanks Bill, that's exactly what I was looking for (and thought would be true).

I'll be attempting the install myself, and it's the first time I've done a gear install. I feel confident that I can do it, but I don't think I'll be welding any 9" housing ends onto my rear anytime soon. So, I'll just keep the C-clips and break them so I can be mad at myself.

BTW, if I break this thing, I'm going to give up trying to auto-x and buy a locker.
