4.88 gears in 8.25 and the 35

anyone who did this did you just need to order just the ring a pinion kit or did you need a hole new housing for the gears too?

When you say "housing for the gears" do you mean the carrier which the gears mount to or are you asking about the actual axle housing itself?

assumming that you had stock gears, then yes for the 4.88 gears you would need to upgrade to a carrier that will fit that gear range.

You do not need a new carrier for 4.88 gears in a C8.25. The carrier break is super low - like near 2.56 or something. No need to worry about it on XJs.

----------------------------------------
Ring Gear Diameter: 8.25"
Cover Bolts: 10
Carrier Breaks: 2.45 / 2.56
Max Recommended Tire Size: 33

Edit: go do a google search for "carrier break 8.25 chrysler" and you will see plenty of pages that say the carrier break is non-existent for XJs (because our gears are numerically too high)

In a Dana 35, the carrier break should be 3.55 and higher use the same carrier. If you have 3.55 or higher gears, there is no need to change carriers. If you have the 3.07 gears (manual) you will need a new carrier.

Edit: confirmed here: http://www.quadratecforum.com/showpost.php?p=863578

2nd edit: As someone who has regeared a Dana 35 rear axle and wasted the money...Don't waste the money. Find another rear axle (C8.25, D44, or Ford 8.8) and regear it.

Good advice, though I might add that a LATE MODEL 8.25 (29 spline) is the one to look for if going that route. I don't think an early 27 spline would be worth the effort.
