Axle Spline confirmation
 

2004 Ranger EDGE (WOO WOO)

Has the axle code 97 (Open diff)
Has the gear ratio of 4.10
I do believe it is an 8.8 but would me thinking that the 8.8 is a 31 spline be wrong or would I be right?

Edge = 28spline. Probably 8.8.

If it's in a 2004 Edge it would be 28 spline. The only Rangers i know of that came with 31 spline axles are FX4 Level 2 trucks. And those are definitely not open diff. The 2003 and 2004 Edges that I have both are 4.10 gear ratio but 28 spline axles. The 2002 FX4 that I have has a 4.10 Torsen limited slip and is a 31 spline. I hope this helps.

28 spline....I have the same axle code on my 01 wreck.

According to the TRS Axle guide it says the 97 code on my year model is a 8.8 with 4.10's

Oh okay I thought with the 8.8's it was 31 and with the 7.5's it was the 28 spline. My mistake

I think only FX4's came with the Torsen 31 Spline 4.10 8.8 LS

So If I were to upgrade to a 31 Splin LS, I would need new axle shafts wouldnt I?

31 spline shafts won't fit in your 28 spline axle tubes. If you wanna go 31 spline you'll have to get a complete axle.

lol Im glad you said that now because tomorrow I was going to bu a 31 Spline LS out of a Pony
