RE: New Era's H4x4?
I built my e-maxx with all new era parts,i got the extended chassis and added a 2 inch extension plate i made one on top and one on bottom.It is very strong and this truck is heavy with 3 servos and two 7 cell battery's i have never had a problem.
I now have a 14.25'' wheelbase because of my extension plate you can make one yourself with alum from the hardware store.
