in 2008 i used their r2 2 speed, but it was in my heavy Super. it broke in 3 feet. Maybe it was an early version and not meant for a heavy rig, but I drove slow. I think it was the sudden stop that broke the 2 speed mech.

Strong reliable but bigger is the summit trans or emaxx trans.

Does that help?

My rc4wd beast came with one. Besides a crappy servo horn it works fine. This rig weighs in about 10plus pounds and 3 axles. It does have limited gearing options and has been known to fail. The more proven summit tranny would be my choice. Both for strength and the gearing is spur and pinion based for more options.
