www.powerlineracing.com hop-ups
www.nitrohouse.com place to get replacement parts
these sites have all the parts you need for the truck. Most of the parts from the monster pirate will fit, there are only a few minor differences and even the parts that look different can be swapped between the two trucks. The diffs are different in the dominator but they fit in either truck. the shocks have different hole sizes in the pistons too. All the aluminum hop ups will fit unless it says so. Any tires for the max or savage will work on the dominator wheels
