DriveLine

At the heart of the driveline is the Drexler Limited-Slip Differential. This fantastic device allows the traction of a solid axle with the maneuverability of an open differential. It is fed power via a low-friction chain drive to a genetically optimized aluminum rear sprocket; and transfers it through tripod bearings and 4140 alloy steel half shafts. System architecture choices were made for reduced complexity and weight at no penalty to reliability.
