...the chassis is actually quite long...Almost big enough to take a Hellfire stock body...Too long for the E-Sav but probably good for the GP conversion...
...The drivetrain will take what you throw at it for sure...Especially when mated with the GP front and rear diffs...
...You can read ALL about the E-Savage at, surprise surprise, E-Savage.com
EDIT: Here is one shot of the original extended chassis...These are EP diffs front and rear, NOT the GP diffs like the chassis we are talking about...Gives you an idea though...
