full spool or selectible

[hps4evr]

im not shooting down some of these ideas but the auburn is a clutch type limited slip, the clutches will wear out and need replacing. it may be 10 years from now but they will wear out. if a selectable locker is your choice the elocker and arb dont use clutches. i think the spool is cheap, tough and predictable. but it will wear your tires. so if you run cheap tires then who cares. if you drop a couple grand on tires you may want to make them last. a detroit could be a happy medium between selectable and spool. something to think about. even your driving style and what you want to be able to do with it should affect your choice. if you want to wheel hard all day and not give up an inch, then spool it and live with the quirks. otherwise spend the extra coin.

I agree the Detroit would probably be best.  But I like the idea of no maintenance spool

As for tires the jeep will not be a daily driver after this build but it will be out and about

So havin a spool in the rear in my mind is easy cheap and strong. Fine I'll wear my tires out a bit fast. But I can live with that.

Then I'll put a selectable locker in the front

Air or electronic is the new question

I agree from what you are saying it sounds like you are a good candidate for spooling the rear.

The front is simple, electric. Easier to install, less maintance, no lines to freeze up in winter, easier to repair on the trail.......

Thanks.  I will be posting picture as the diffs get built

If you are going to run hubs you are actually better off spooling the front, and selectable rear. As long as you have hydraulic steering of course. But you wouldnt run anything over a 35 without hydro assist or full hydro anyways.

That setup also makes true cutting brakes possible.

You stay in 4wd and just brake 1 rear tire, then pivot on it in 3 wheel drive.

Thats how most comp guys run a spool/selectable combo.

You get all the positives, and none of the negatives. Still get simplicity of a spool, and reduced cost. Turn the hubs out (or pull slugs) on the road and get normal tire wear.

You want to make sure you have a good steering angle to make it work though. You should able to clearence stock type knuckles and axles to get right around 40 degrees which would be perfect for the above setup.

basically you need to be able to turn tight in order to overcome the scrub in the frontend from being locked solid.

There's tricks you can do with the steering angle (ackerman) to further help with that as well.
