Hey guys,
New to the forum and you seem like the people that can help me. I've got an '01 dakota with the 9.25" rear and a 3.55 ratio. I'm wanting to go to a 2.94 ratio, but am having trouble finding a set of 2.94's for that rear. I have found an 8.25" rear that already has the 2.94 ratio in it and all its other dimesnions will work for me. My question is, is there any chance that the brakes from my 9.25" will bolt onto the 8.25" tubes? I'd love to keep the big brakes, plus I just redid them. I know I'll have to do wheel adapters and such, but will the brakes fit?

Thanks a lot

9.25 brakes are larger, fittin to the tubes wont work as the 9.25 is a 3.5" tube and 8.25 is 3" tube, i would recommend the 3.55 over anything taller, 2.94s? lowest ive ever heard is 3.24s that were for 5 speed 4cyls

I have an automatic with the four cylinder, and the 2.94's will put me right where I want to be. Anybody on here got a set of 2.94's for the 9.25"? I forgot to mention that the engine is a cummins.

Thanks

Wrong. the brakes are identical.

I know because I took brakes from an 8.25 (disc) and put them onto a 9.25 that was previously drums.

if you look at the 9.25 axles, they actually neck down at the ends, whereas the 8.25 tubes are the same diameter all the way to the center section.

If you're looking for a super light duty, economical cruiser, then yea, swap out to the 8.25 axle. but if you plan on puting any torque through that drivetrain from hauling weight or towing, you'll explode that 8.25 with the torque of a turbo diesel, even if it is a 4 banger. keep the 9.25
