RE: Project bulletproof stampede!
I would stick with RPM parts. Aluminum is not your friend when you start extreme bashing. It will just bend and then you get to throw it in the trash. I also noticed you have the steel diff but the aluminum idler. I'd swap that out for the steel idler. The Steel top gear and diff gear will eat up the aluminum idler. I made that mistake.
Not sure the big bores are worth the money. When I need shocks I typically just search Ebay for someone parting out a Losi or assoc truck. I have XXX-T shocks on one of my Pede's. It sits slightly lower but I'm happy with it. Best part is I can typically get them for about $20 shipped and they've taken all the abuse I can throw at them
