Thanks for the review MountainBikeRoamer. For the same reason, that it is a mechanical locker, I researched the OX Locker for my '99 E350 with a Dana 60 full float with 32 spline axles. In this case I'd swap to 35 spline axles.

It is on my build list but, a ways off before I eventually get to it. I'm curios, do you mind sharing how much the locker and install cost you? To do the axle swap, install the locker with new bearings etc I'd be around $2100 or more.

Also, please do let us know how this thing performs and where it allows you to roam that you previously where not able to reach.

It looks like the parts totaled around $1900, not including labor.
This accounted for *everything*......the locker unit, gears, bearings, all gaskets/seals, gear oil, cables for the OX Locker actuators, etc....

Your part costs would obviously be cheaper if you're not re-gearing.

This part total was for a pretty thorough rebuild of the rear axle. All bearings and seals were replaced throughout, and the rear was also re-geared to 4:10 using Dana Spicer OEM gears -- and there may have been slightly less-expensive gears available from a different vendor. These were around $400 or so for the set alone, so if your gearing is already where you want it, you're that much ahead of the game.

If you're curious, here's the complete part list.
