YearOne’s Differential Kits Are A Driveline Delight


 

One of the most arduous tasks of any restoration is parts selection. While rebuilding something like a rear end seems straightforward, there is a litany of components within that take careful research for correct fit and performance. Seals, shims, bearings, gears, axles, oil, and the differential itself all have to be gathered with each other in mind for cohesive cruising.

YearOne can ease a bunch of that burden with their new differential kits. Available for both 489 case 8.75” and Dana 60 rear ends, each package is comprised of a ring and pinion set, Timken master overhaul kit, and clutch-style limited slip. Basically, one box brings home everything that’s needed for a complete turnover of the center section.

Gear sets for 8.75” applications include 3.23, 3.55, and 3.73. Big boy toys with a Dana can pick from 3.54, 3.73 and 4.11 ratios. Within the overhaul kit are top-quality bearings, races, a pinion nut, pinion seal, gasket, crush sleeve, shim kit, and ring gear bolts. They even threw in some marking compound to verify setup once it’s all together.

The cherry on top is that since these parts are all being bought as a kit, the savings are significant compared to buying them piece-by-piece. Furthermore, everything is brand new so there are no concerns with chipped pinion teeth, cooked clutches, or burnt bearings…but some new tires might be on the shopping list soon.
