Traxxas 5742X Blue Aluminum Rudder Mount with Hardware for Spartan SR

The Traxxas® 5742X Blue Aluminum Rudder Mount is a direct upgrade over the stock plastic rudder assembly on the Traxxas Spartan SR RC boat. Blue-anodized aluminum construction delivers dramatically improved strength and durability, while the included stainless steel hardware ensures corrosion resistance in the harsh marine environment. At high speed on the water, precise rudder alignment is everything — the 5742X keeps it locked in where plastic can’t.
