Need center diff help…

[xcntrk]

Hey all, could use some advice about a center diff setup. I just converted a Ofna Hyper-7 over to electric using an RCM mount, Neu 1512/2.5d on 4s. I replaced the center fluid with 130k, new seals, and run 46/13 gearing.

First run out everything performed well for about 10min until I blew the center diff. Prior to the damage the front-end still seemed to unload a bit slipping the center diff nearly all the way up to top-speed before it seemed stopped unloading; even with the heavy 130k. Upon teardown, the entire diff gearing is shot. One bevel gear and all 4 spiders teeth are munched.

Is there a logical upgrade for the stock center diff? Something strong, perhaps a 6-spider, maybe a torsen-style? Or should I just replace/fix the damaged gears and give it another go? Is the center diff the same as the front/rear diffs? What fluid should I be running or is this dependent on number of spider-gears?
