Coming from Pro-Line and made for the Pro-MT 4×4 monster truck are three new heavy duty aluminium and steel upgrades. First up is a set of aluminium shock caps that add strength, durability and style to a very important part of the truck. The caps are made from CNC machined aluminium and come gunmetal anodised to perfectly match the rest of the truck and have large laser engraved P-L logos on the front and back of the caps. The shock caps come in a pack of two with new inner diaphragms and they are a direct stock replacement upgrade.
Also new is an aluminium servo saver arm for the Pro-MT 4×4. The alloy upgrade improves overall durability of the steering assembly, adding strength and making for improved steering emphasis on high-bite surfaces or when the goings gets tough. The servo saver arm is a direct stock replacement upgrade and will enable drivers to also tighten down the servo saver spring for a more precise steering feel. Last but not least is a steel spur gear for the Pro-MT 4×4. The steel gear adds strength and durability as it is CNC machined from hardened steel and black oxide coated to avoid rust. The steel spur gear has been narrowed compared to the stock gear to reduce weight and friction for smooth and quiet performance.
