t-maxx aluminum bulkhead, help please

You can mod your stock bulks to make them much stronger, but you have to give up the bumpers.
Get a set of RPM bulk braces and a front titanium skid. Remove the front bumper and install the RPM bulkhead using only the lower screws. Line up the top holes in the bulks/brace and cross drill the brace so you can run a 50mm M3 bolt through both bulks and the brace, using flat washers on both ends of the bolt. Install a nylock on the bolt and snug it down. Remove the lower screws, cross drill it and install the bolt and washers the same as you did for the top screw, again, snugging everything up but not to final tightness. Install the titanium front skid and tighten all the screws holding it on. It wouldn't hurt to run longer screws through the skid where the center braces attach. Use a long enough screw that you can put a washer and screw on top of the center braces and tighten all the skid screws down. Once you have the skid screws good and tight, do the final tightening on the long bolts and nuts you installed in your bulk and brace. The titanium front skid will act like a bumper as it takes a very hard hit and just bounces off rather than folding like an aluminum skid, or breaking like a plastic skid.
You can do the same thing to the rear bulks and it will protect your truck from bad landings, but it's not as vital as doing it to the front.
If you do both ends of the maxx this way and add a set of good aluminum lower braces, it's almost impossible to break a bulk. I raced a tmaxx for several years and after doing this to it I never broke another bulkhead.
Here's a pic of a rear clip on an e-maxx I built for a guy showing the cross drilled bulk and brace.
