Cobra 8.8 IRS axle clips
« on: September 27, 2024, 05:06:31 AM »
I am still struggling to find axle clips for my 8.8 IRS. When searching, all I keep coming up with is the c-clips that aren't used in my setup.

I need the part in this pic, though that still isn't the setup I have. I don't have 4C130.

Ideally I just want to get them from rockauto but cant find them on there either.

Just found this bit of info:

Note: Whenever you have a shaft pulled, it is a good idea to check those snap rings, or "circlips" on the inner stubs (no, they are not "C-clips"). There had been a rumor that the inner grooves of the traction-lock carrier could have been machined incorrectly, making the snap rings fit extremely tight (and susceptible to damage when they come out), but I have never been able to confirm that. My $0.02 is that since some rings are made from flat stock - like the ones I had - it causes them to catch on the inner groves, hence the extra force needed to extract them. If you have those, grab another set from Ford, 1L2Z-4B422-BA, which hopefully are a round wire and will allow the axles to come out much more smoothly. If you still have trouble, a 1-5/8" tie rod separator, such as the PowerBuilt 647056 works great. You can rent the AutoZone set with that one in there, or buy one of your own for the tool stash: a couple taps with it between the differential and hub will pop the axle right out!

My axles were an absolute pig to remove, so maybe this is why? I will try and source the part number mentioned and see if they fit.

Struggling a bit. Ebay is going to cost me $40 for a 50c clip that I don't know will fit. No luck on RockAuto.

I (or someone in the US) could get them from a dealer and ship them over?

If you've got the dimensions of the clip could you try some gearbox specialists over here as I'd imagine its a standard part.

This could be worth a try as they seem to have 8.8 parts in the uk, but I've never used them.

Pages 236 to 239 of this have the different circlips & part numbers in the EMPI range, might be of some use?  The Ronin kit uses boot kit EMPI 86-2215 that does have these clips and they're round.

Installing the inner stub axles was a right pig of a job due to these circlips, I had to tweak the shape slightly.  I definitely don't want to remove them.

I will look into that thanks Rhino. Unfortunately one of my seals is leaking even though they are pretty much new. I thinknI may have damaged it trying to get the axles out last time.

If that fails I might take you up on that offer Digi.

I asked Empi what clips come with the Ronin setup and they said its # 87-3138-a.

I am.notnsure of the significance of the -a but the catalogue shows 87-3138 @

24.55mm I.D. 2.45mm Thick Rectangular

Pretty sure that won't fit mine. Looks to be a flat clip, but in the wrong axis. FYI I have driveshaft shop built axles from the Samberg era.
