This is an optional Serpent SRX2 4-Gear Transmission Set for low traction applications.
The SRX2 MH kit includes the standard 3-gear standing gear box, as well as the 3-gear laydown gear box; this 4-gear set now completes the lineup.
The set includes the light machined aluminum motor-plate, the transmission cases, idler shafts, gears, bearings and hardware.
The 4-gear standing transmission will work well on low to medium traction tracks and is easier to handle/more forgiving compared to the more aggressive 3-gear standing set-up (which is used a lot in the stock-class).
