Cheapest is often to find a Sure-Grip 3rd member in the ratio you want. Best? That's dependent upon use. Locking differentials tend to be a bit harsh. Clutch type without preload will still spin one tire on snow or ice. Preloaded clutch type (Auburn) aren't rebuildable. If not drag racing on slicks or prioritizing best Winter traction I like the bevel gear type as they are smooth and put the power down well: https://www.summitracing.com/parts/dtl-913a572 The entire differential case generally gets replaced unless you use a Lock-Right. https://www.summitracing.com/parts/pwt- ... plications See many options here: https://www.ringpinion.com/DiffWizard.aspx Select Chrysler and then the 8.75" with your case casting number '41, '42 or '89 and then Traction devices to see what is available. |

You're highly unlikely to break any of them unless you're drag racing with a stick, running slicks and dropping the clutch at high RPM. |
