Got a complete Akula chassis conversion which replaces front, rear and the bit in the middle with alloy. Fairly tough alround and has alloy hangers.

Alternatively you can pick up the Kevlar front end or the uprated one that has the extra screw in the middle. I can't remember the number of the top of my head but if you want it I'll look it up.
