Its pretty much the same "center" driveline as the Rampage. There are a few changes but it is essentially the same. There is no center diff, its a spool just like the original Ramp. The gearplate and gears should be interchangable between the 2 models. I wasn't able to discern any huge between between them visually. The tire compound is fairly hard, its noticeably firmer than a stock HPI Dirtbuster. They should last a prtty good while if you do not abuse them on concrete.
