Im fixing to buy new gears for my 2001 4x4 slt 318 and i dont know which rearend i have and which spline or whatever. When it comes to gears im lost so any help would be awesome.

Is it a 4x4 or a 2WD? (edit: I'm dumb too, because I didn't notice you mention it was a 4x4)

If you have the 1500 (1/2 ton), you have the 9 1/4 rear and the Dana 44 front. The 2500's came with the Dana 60's and the Dana 44HD front, and the 3500's came with either the Dana 60 (single rear wheel) or the Dana 70 (dual rear wheel) and the Dana 60 front. As for the spline, I'm not sure, but any reputable shop should know the spline count based on year and axle (I think all 9 1/4 rear had the same spline, but I don't know for sure).

If I'm wrong on the 2500's and the 3500's, someone let me know, but that's what pops in my head (I'm more used to the first gen 3/4 and 1 ton trucks than the second gen rigs).

 

OK thanks for all your help man. I have one more dumb question do i need to buy gears for the front and back or just the back. Where would u recommend me buy them from and do you suggest any certain brand

 

No problem. I always love to help if I can, because I need some help from time to time.

If you're going to re-gear the rear, then you need to re-gear the front too, other wise you'll get a driveline bind and start breaking things when you put it into 4WD. The best place I've heard of to get gears from is Randy's Ring and Pinion. From what I've heard, they have great prices, great knowledge, and even better tech. support. I'm sure a few others will post their favorite suppliers too.

 

2500= 60F/60R or 60F/70R or 2500 Diesel and V-10 manual transmission 60F/80R (a hybrid Dana 80)
3500= 60F/80R

 

Thanks for the info. I had a feeling I was wrong on the 3/4 and 1 ton info.

 

Will 4:10 gears fit in the stock 9.25 1500 4x4 rearend?

 

Yes, you can go as big as 4.56 in that diff.

 

Would you go with 4:10 or 4:56? I have 35in tires and might go to 38's.

 

Without a doubt, you should go with 4.56. That would be perfect for 35's, and helpful (but not ideal) for 38's.
