Product Description

The Yukon Gear YPKD44-S-30-JK Standard Open Spider Gear Kit is engineered for the rear Dana 44 axle in Jeep Wrangler JK/JKU vehicles (2007-2018) equipped with 30-spline axles and an open differential. This kit provides all the internal spider gear components needed to rebuild the axle carrier when the factory spider gears are worn, chipped or failing under heavy use.

Manufactured to higher standards than many OEM replacements, the kit features upgraded material and precise manufacturing that improve durability and reduce noise. Because it's specifically for open carriers--not limited-slip or locker units--it's important to confirm your differential type before purchasing. This set is ideal for trail vehicles, off-road builds or general rebuilds requiring a reliable drop-in solution for the Dana 44 rear axle with 30-spline configuration.
