This is the new Pro-Level Rear axle kit for the 1G AWD DSM. These axles feature much larger aerospace grade 36 spline bars (factory are 30 spline), billet ball & cage inner CV, and a Porsche-style 108mm outer CV with a conversion plate and hardware to mount the 6-bolt cv to the factory 4-bolt hub flange. The strongest axles to date for the 1G AWD.
