Carrier and pinion bearings, shims, crush sleeve, seal and ring gear bolts for setting up gears in a Dana 60 or 61 differential, 1966-1998.
If you are putting new gears in a Dana 60, or chasing a howl from a tired one under an older 3/4 or 1 ton truck, the gears are only half the job. The bearings, races, shims and crush sleeve that hold them in position wear along with the teeth, and reusing them is the fastest way to turn a fresh ring and pinion into a noisy one. The Allstar Performance ALL68534 puts those wear parts in one box for Dana-Spicer Model 60 and Model 61 differentials built from 1966 to 1998.
A Dana 60 locates its pinion on two tapered roller bearings, a head bearing next to the gear and a tail bearing near the yoke. A shim stack behind the head bearing race sets pinion depth, and a collapsible crush sleeve between the bearings sets pinion preload when the nut is torqued. The carrier rides on two more tapered bearings, and the shims behind them set both carrier preload and backlash. Every one of those dimensions changes when the gear set changes, which is why a regear calls for new bearings and fresh shims. Summit Racing's spec sheet for this kit lists head, tail and carrier bearings, pinion and carrier shims, a crush sleeve, pinion seal, pinion nut, ring gear bolts and a cover gasket, and it identifies the kit for a 29-spline, standard-rotation Dana 60/61 with 12 ring gear bolts and a 10-bolt cover.
Pull the cover, drain the oil and look at the ring gear teeth and the oil itself. Grab the yoke and check for in-and-out play, then spin the carrier and feel for roughness. If the gears are clean and you only hear a rumble, bearings alone may cure it. If the teeth are pitted or you are changing ratio, order gears and this kit together. Our Dana 60 ring and pinion buyer's guide covers rotation and carrier break so the gears you pick match this kit, and the Dana 60 rear axle problems guide walks through what wears first.
The listing covers Dana-Spicer Model 60 and 61 differentials from 1966 to 1998. That includes the Dana 60 rears and low-pinion fronts used under older Ford, GM and Dodge heavy-duty pickups and the Dana 60 rears used in some muscle cars. Summit's data lists the kit as standard rotation with a 29-spline pinion. High-pinion, reverse-rotation fronts such as the Super Duty Dana 60 and later axles with different bearing sizes are not covered by that description, so check before ordering. Dana 60s were built in many versions over three decades, so match your axle tag and bearing numbers, or send us your year, model and VIN and we will check it. Pair it with gears such as the Yukon Dana 60 4.56 gear set or the taller Revolution Dana 60 3.55 set, and browse the rest of our differential and transmission rebuild kits.
A Dana 60 housing has to be spread slightly to get the carrier in and out without damaging the bearing bores, so have a Dana 60 housing spreader on hand and never spread past what the tool maker recommends. Revolution Gear and Axle publishes these Dana 60 starting points: 0.052 in starting pinion depth, 17-30 in-lb pinion bearing preload, 0.006-0.010 in backlash, 110 ft-lb on the ring gear bolts and 80 ft-lb on the bearing caps. Start with the original pinion shim stack, press the new head bearing on, install the new races, then crush the sleeve slowly and check rotating torque often, because an over-crushed sleeve has to be replaced. Shim the carrier for backlash and preload, then paint the teeth with the supplied marking compound and read the drive and coast pattern before final assembly. Use thread locker on the ring gear bolts, install the new pinion seal with the lip facing the oil, and fill with 75W-90 or 75W-140 gear oil, adding friction modifier if the axle has a clutch-type limited slip such as a Power Lok. Drive gently for the first few hundred miles and change the oil early.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It contains the bearings, races, shims, crush sleeve, pinion seal, pinion nut, ring gear bolts, sealant and marking compound needed to install a gear set. Order the gears separately in the ratio you want.
That axle is a high-pinion, reverse-rotation Dana 60 built after 1998. This kit is listed for 1966-1998 standard-rotation Dana 60 and 61 axles, so it is not the right kit for that truck.
It is not worth it during a gear change. New gears change pinion depth and preload, and worn bearings or a reused crush sleeve are the most common cause of noise after a regear.
A housing spreader, a bearing puller and press or driver set, an inch-pound torque wrench or beam gauge for preload, a dial indicator for backlash and a large breaker bar to crush the sleeve.
75W-90 or 75W-140 gear oil. Add friction modifier for a clutch-type limited slip, and change the oil after the first few hundred miles of break-in.
