Dodge Dart Differential Information

A car differential

Though Dodge produced several different vehicles from 1960 to 1976 with the "Dart" nomenclature, it is the compact giant-killer produced from 1963-76 that garners the most attention. This incarnation is the most commonly hot-rodded, and (arguably) the most beloved of the series.

Basics

Sports versions of the Dart used the 8 3/4-inch differential, while straight six versions used a smaller, weaker version of the same.

Sure Grip

This is Chrysler's name for a posi-traction or locking diff. This type uses a series of clutches in the diff that lock the rear tires together under acceleration.

Interchange

In general, Dart rear-ends will interchange with similarly-equipped mid-sized Chrysler cars of the same generation. These include the Plymouth Valiant, Dodge Demon and Dodge Lancer.

Straight Six Weakness

The diff used in most straight six Darts is considered by most to be a fairly reliable unit at stock power levels, but is known to fail at anything exceeding 300 ft.lbs. of torque.

8 3/4 Rear Ends

Comparable to the ford 9-inch or GM 12-Bolt rear, the Chrysler 8 3/4-inch rear end is both strong and versatile. This is the rear of choice for most big-block clone cars.
