A ratchet type locking differential, the Detroit No-Spin™ was also available for some years and models. We have no service parts for the No-Spin™, but we do stock parts for the Powr-Lok™ Limited Slip.

1991-1993 Dodge Dana 71 rear axles with the 3.07 ratio can use all the ABS compatible 3.31-4.10 ratio differentials. 1991-1993 are the only years where the 3.07 ratio was used with 32 spline axle shafts. The Dana 71 has a greater pinion offset compared to the Dana 70 due to the larger diameter of the pinion head.
