Why do people not put them in the 8.25 and use 4.56 even if they are running 35s or 33s for tires.

Is it to much stress on the axle to have it that low of gearing or something else?

 

Cost.
There are limited suppliers for 8.25" 4.88's

 

A lot of people seam to be afraid of gearing. they think it will cause bad gas mileage and to high of RPM's.

Some people like 4.88's and 33's
Some people like 4.56's and 33's

Same thing for 35's...

After using 4.56's for 33's I would recommend this for anyone who plans to run a 33" tire, it was a perfect combo for me. good rpms on highway, better gas mileage then I had with 31's and stock gears.

But I would recommend 4.88's for 35's as with 4.56's its doable and no real complaints, but when I am loaded up with gear headed to the trail/Moab ect, Hills are a bit slower and seams to be just under ideal rpm, and lower side of the power band... Just my opinion.

Cost can also play a role IIRC... the 4.88's are a bit more $

 

whats usually the carrier break on the dana 30 when re gearing

 

3.73 & up.

 

isnt 3.73 the same break for the 8.25 too??

 

4.88s have only been available for the 8.25 in the past couple years

 

There is no break on the 8.25 carrier.

I can't recall ever seeing 4.88's for the 8.25, the lowest I can remember seeing is 4.56. 4.88's everywhere for D30's and d35's.

Point me to a 4.88 for the 8.25 if you have a link please.

 

Nevermind, found em' at Serious Offroad!

 

i see you have a ax15 with a 4.5" lift, what did you use for the rear ds

 

I still have the stock rear driveshaft, no SYE.
