Ok so i'm upgrading my t maxx 2.5 to a 3.3.I just got the 3.3 driveshafts,knuckles,and turnbuckles.i noticed the 3.3 knuckles are taller than stock wich causes the a arms to set at odd angles.do i need to upgrade the bulkheads to?it seems the 3.3 driveshafts would hit the a arms during heavy suspension travel.not sure.... Any help would be great.
Thanks guys for helping a newbie

If you really want to upgrade your truck quit buying the next generation of STOCK parts and buy RPM parts. You are just trading stock for stock. That's not technically upgrading. Buying RPM 2.5 parts would be an upgrade, or RPM 3.3 parts. I'd much rather drive a 2.5 truck with all RPM parts than a 3.3 stock.

While i do agree i got these parts for 15 bucks.and i plan on eventually going all aluminum on this truck.i have 2 t maxx's this one will be street only.but for now I'm just trying to get it together.if i need to upgrade bulkhead i will go ahead and get the aluminum ones.this will be a slow process as this crap ain't cheap.lol

have to join the revo-lution on this one; you might want to look into just selling your 2.5 and getting a 3.3 roller and doing the upgrades from that; might be more cost effective and better in the long run

Appreciate the advice guys....but I've already got the parts and engine and some goodies too.so for now I'm gonna run with it.i had considered just getting a 3.3 but the truck was practically free so what the hell.
