The 'bullet proof' piece for your high powered DR10M build. Heavy duty machined alloy gearbox that keeps your gears in perfect alignment, even under the heaviest motor rpm loads. The '3 Gear' option rotates the motor around and uses 1 less idler gear like other traditional drag cars for use on higher grip surfaces. 1 less idler gear makes the transmission more efficient, quieter and translates to more rpm. The chassis will feel 'flatter' too when launching from start. Includes a reversed, light weight motor plate. Direct bolt on for the DR10M only. Polished and anodized black using 7075 aluminum.
