HPI new for the Nitro MT 2 truck owners are heavy-duty option parts that are made to handle extreme conditions, racing and high output engines. These heavy-duty parts are made from high strength steel and chrome plated for extra durability and custom looks. Increased durability prevents breakage, so racers spend more time driving and less time doing repairs. Our Team Drivers have seen extended life of up to 5 times the stock parts, so the long-term replacement costs are lower. The shiny chrome finish makes the truck look great, and helps prevent dirt build-up on the parts. These heavy-duty parts will be popular items for Nitro MT 2 owners, and our Team Drivers highly recommend them for replacement parts.
