Looking at building a 1.9 rig and I’m looking at transmission options. I want something with the motor mounted up front. With a transfer case of some sort. Kind of leaning towards an RC4WD r3 single speed. However I was wondering if anyone had experience with them. I have a roc412/MMP and currently run it on 3s in my current truck. Will their transmissions and t-cases hold up in what will prob be a pretty heavy truck.
