Axle and brakes

im looking for a ford 8.8 for my TJ, im about to run 35x12.50s, so i was wondering what size of disk brakes and what gear ratio i should have?

96 or newer 8.8's all have disk brakes on them. However the older ones still have a bigger drum setup than the TJ does so braking will be somewhat improved no matter what.

As far as the ratio's go. 8.8's only come in 2. Either 3.73 or 4.10. So if you have one of those ratio's in your rig already then you can save some coin by not having to re-gear the front right away.

Of course it would be good if you geared it to 4.56. Are you running an auto or manual?

With an auto and 35's I'd say that 4.56's would be a perfect mix for you of on road useability and off road gearing. If you were running a manual you would need to be at 4.88 to be the same. However if you don't mind having the RPM's run a little higher on the highway then going to 4.88's will help you even more when you are down in 4LO.

I'd say that depends on what gearing is in your TJ now? If you can do one or the other without having to re-gear the front then all the better.

If not then you are either going to have to re-gear the front or remember to NEVER put it in 4wd until you do re-gear it.

And honestly it's almost like wasting money to re-gear twice. Maybe if you are going to need to re-gear one axle you should just wait and do your 8.8 swap when you can have your final ratio in there?
