I have a ? about the turbo plugs i see that you can get them but i dont see where you can buy the heads for them. also i got a twin truckzilla for christmas. i know this is gonna create a lot of stress on the drivetrain and i was wondering what to do to beef it up i have already bought the harden differentials, the duel brakes, and the heavy duty brake hub. the only reason i the twin engine because it was the only thing i could think of i wanted for christmas. also i have got the intergty heavyduty shocks what would be a good shock oil to use for bashing around the yard.
