Kyosho Aluminum Lightweight Differential Bevel Shaft (2)

Substantial weight difference compared to stock steel crosspins. Rotating mass is reduced if you use thise pins in all 3 diffs, and I know from experience that these pins will outlast the gears and outdrives by a long shot. The internal diff gear material is much aofter than these hard anodized pins. These pins won't save you from being a horrible, inept driver, but they will certainly lighten your drivetrain.
