Axleshaft length

they dont fit. get the proper part for your application, they are not the correct length.

just buy 31 spline axles from Superior, Alloy, Moser or whoever you want.

1979-1993 8.8's - 29 3/16" axle lengths
1994-1998 8.8's - 29 31/32" axle lengths
1999-2004 8.8's - 30 11/16" axle lengths

The 1998 and earlier had shorter axles, and I wouldn't recommend trying to use them. Just get the 30 11/16" axles. I would prefer Strange axles over anyone else. Their 1550 and "Hy-Tuf" thru hardened axles are very strong.

If you plan on keeping the ABS functional, it is going to depend on how thick the c-clip eliminators are. "Normally" there is plenty of room between the outboard face of the eliminator and the inside surface of the ABS reluctor (exciter), but since the ABS reluctor (exciter) is pressed onto the axle shaft, sometimes they are not always pressed on in an equal length from the back of the axle flange. Make sense?

C-clip eliminators are generally specific to the axle you order so just verify that with whomever you order your spool and axle set from. I'm sure you already know this, but just make sure you get the 31 spline spool as well.

If you do not plan on reataining the ABS system, then just order the axles without the ABS reluctor (exciter) rings.

Be careful when you push in the axles to remove the factory axle c-clips, the ABS reluctor (exciter) ring can mistakenly be pushed into the ABS pickup sensor and damage it.
