The SSD Trail King Scale Transmission & Mount Set offers an incredibly realistic, motor forward transmission design for multiple applications. This is a direct replacement for the SSD Trail King, but can also be used with the SCX10 II, when combined with an offset front axle (SSD00370 or SSD00398). This transmission keeps the motor low, to keep CG in check, while at the same time positioning the motor weight in front of the skid, for improved fore/aft weight bias. Plus, this transmission will allow the use of the SSD Scale V8 Engine Motor Cover (SSD00299), allowing you to add even more detail to your build. NOTE: For assembly instructions see Trail King manual in the resources tab above - page 10. For SCX10 II fitting this transmission requires an offset front axle (SSD00370 or SSD00398) Features: Injection molded nylon transmission case CNC machined aluminum motor mount Hardened steel 48p gears and shafts Realistic scale design Front mounted motor Injection molded nylon transmission mount/skid Direct fit into Trail King chassis Fits into SCX10 II chassis Fits SSD V8 motor cover (SSD00299) 11.8:1 Ratio Includes: Scale transmission kit Motor pinion gear Mounts and skid Bearings Hardware
