HPI Racing now offers a Heavy-Duty Final Gear Set for the Nitro MT 2 line of 1/10th scale trucks. These are standard replacement parts for the powerful Nitro MT 2 18SS trucks, and can be installed on the standard Nitro MT 2 trucks for a significant increase in drivetrain strength and extended maintenance intervals. Precision machined from special heat treated steel, these heavy-duty gears are highly recommended for Nitro MT 2 owners who have upgraded to powerful engines and for extreme off-road driving conditions. The set includes one 38 tooth ring gear and one 13 tooth bevel gear, two sets are required for a complete upgrade to the Nitro MT 2 truck. Not recommended for the original Nitro RS4 MT due to fitment complications.
