hybrid diff>>1/8th gears that don't fit.

Yes. The ones that come with the RCM Revo Hybrid Diffs are hardend. Just try and tear them up. I was blowing stock revo diffs almost every time I ran the truck untill I got this upgrade. Havent had an ussie since. Only thing I ever did was take them apart to change diff fluids and inspect. They still looked new after months of abuse. Best upgrade ever for the revo IMO.

^^^ I agree, I got more power than any , ANY italian nitro, going through mine and no problems. I'm running a Neu 1515/2.5d (1700kv) on 5s and they don't complain. Like Jhautz said "Bar none the best upgrade for a revo based truck" I am thinking of going to HB diffs in my UE set in my Gmaxx

Will the Mugen MBX5T gears fit the RCM cases?

I notice they have a 4.6:1 ratio. It's a 46 tooth ring with a 10 tooth spiral pinion gear.

One way to tell which gears will work is to measure the ring gear. It will need to be no larger than 38mm (1.500 inches).
