Tech Note 1: Conversion Kits

Tech Note 2: Included Components

Tech Note 3: U-Joints Preinstalled
TKA4946 Axle U-Joints included in TK4942 Kit will be pre-installed in your new outer axle shafts. These u-joints are special Torque King® conversion u-joints that fit the Dynatrac outer axle shafts (Spicer 1480 series yokes) and your original AAM 1485 series inner axle shafts. Our direct-fit U-joints eliminate the need to use snap ring spacers supplied in the Dynatrac Free-Spin™ Kit.

Tech Note 4: Ram 3500
If you have a Dodge Ram 3500 dually, your factory dual wheel hub adapters will have to be changed as they have insufficient clearance for the new lockout hubs included in our Kits. Order optional QU42072 Dual Wheel Adapter Set.

Tech Note 5: To Install
To install TK4942 Kit, you need to remove the original hubs and axle shafts. Depending upon age, mileage, and use, your truck may also need inner axle shaft oil seals, ball joints, brake parts, or pinion seal. Inspect the axle before disassembly for worn or damaged parts and order those extra parts/tools you desire for a first class job.

Tech Note 6: Ball Joints
We also stock TK42058 Dynatrac, Heavy-Duty greaseable/rebuildable Ball Joints and TK11266 Carli Extreme Duty Ball Joints for your Dodge Ram.

Tech Note 7: Kits
Torque King Premium TK4942 Kits INCLUDE QK4964 Tool and Lube Kit which has the extras you need for a pro-quality installation. All the components are also available separately. QK4964 includes:
QT1505 Wheel Seal Installer
QT1100 Drive Handle for Seal Installer
(2) QU90018 14 oz. Tubes Pyroplex Plus Synthetic Grease (One is used to fill the Bearing Packer)
S9975 Anti-Seize (Use between the spindle and knuckle and on the brake shield mating surfaces)
QT9404 Brush for applying anti-seize
QT5500 Bearing Packer with Cover

Tech Note 8: Axle Seals
Given the era of trucks this Kit fits, it is recommended you replace the inner axle seals which can become hard and brittle with age. For Inner Axle Shaft Seal Kits with oil seals and installation tools see QK4685.

Tech Note 9: Details
The first time a 2003-2008 Ram 2500, Ram 3500 AAM 9-1/4" front axle has to come apart, it is usually an absolute WITCH to separate the factory wheel hub assemblies from the steering knuckle as AAM did not use any anti-corrosion compound between the wheel hub flange and steering knuckle. The good news is since you are replacing the original hubs, you do not have to worry about them separating or getting damaged during the removal process.

Tech Note 10: Component Differences
The only component difference between TK4942, TK4950, and TK4957 Kits is the lock out hubs. TK4942 includes TK56120 Warn Premium Hubs. TK4950 includes TK11258 heavy-duty Dynaloc™ Hubs. TK4957 comes with QU56112 Mile Marker Stainless Steel Hubs.
