8.8 31 spline shafts question

[escort_gts]

Are the 31 splined shafts the same length as the 28 splined? I have an 8.8 with 28sp shafts and have a line on 31 spline shafts for almost nothing. I know I would need a new carrier but want to know if the 31's are the same length before I buy them.

I dont believe that will work . The axle tubes are larger on the 31 spline 8.8 same as wheel bearings seals ect. Best bet is to buy a complete 31spline axle.

No dice. You need the whole assembly for the 31-spline 8.8, basically nothing is compatible between the two.

This is getting out of hand. Can we please make this a sticky?

ok thanks. I figured i would ask before i spent the $20 on them.

EVERYTHING in the diff except the 2 spider gears that the axleshaft's pass through can be swapped between the two.

agreed




but to answer the question. no, the shafts are different diameter's and different lengths. axle tubes are different diameters.

Technically they are "side gears". The spiders can't be swapped because the 31 spline carrier uses a 7/8" cross-pin and the 28 spline carrier is 3/4".

I added it to the FAQ. Though who knows how much good it's going to do...
