Yukon Dana 44 Standard Open Spider Gear Kit – 30 Spline
YUKYPKD44-S-30
This Dana 44 standard open spider gear replacement kit is designed to restore worn or damaged internals inside open Dana 44 differentials using 30 spline axle shafts. Whether servicing a factory truck axle, Jeep rear differential, classic 4x4 front axle, or custom off-road build, this kit provides the critical internal components needed to bring a worn open carrier back to proper operating condition.
Dana 44 axles have been used for decades across Jeep, Ford, Chevrolet, Dodge, International, and GMC platforms because of their balance of strength, size, aftermarket support, and versatility. Over time, spider gears and cross shafts wear from larger tires, off-road abuse, towing, or lack of lubrication. This replacement kit restores proper differential operation while maintaining factory open differential characteristics for predictable street manners and smooth drivability.
Includes:
- (2) Side gears
- (2) Pinion spider gears
- Cross pin shaft
- Cross pin retaining bolt
- Spider gear thrust washers

Tech Insight
Spider gears are one of the most commonly worn components inside open differentials, especially in vehicles running oversized tires, lower gear ratios, or subjected to repeated shock loading off-road. Excessive spider gear wear can cause clicking, popping, uneven power transfer, or complete internal differential failure if left unserviced.
The Dana 44 remains one of the most widely used light and medium-duty axles in off-road and restoration markets because of its broad parts availability and adaptability. Replacing worn spider gears during a differential rebuild helps maintain proper backlash, smooth differential operation, and reliable drivetrain performance without converting to a locker or limited slip system.
