Yukon Dana 30 Nodular Iron Differential Cover - 10-Bolt
YHCC-D30
The Yukon Heavy-Duty Nodular Iron Differential Cover for Dana 30 Axles replaces the factory differential cover with a thick-wall casting built for added protection and housing support. Whether you're running a trail Jeep, rock crawler, or daily-driven 4x4, this cover helps protect the ring and pinion, locker, carrier, and differential bearings from rocks, ledges, and other trail obstacles. It's designed for compatible Dana 30 front axles using the factory-style 10-bolt cover pattern.
The nodular iron construction adds rigidity around the differential housing, while internal oil-flow shaping is designed to support lubrication around the gears and bearings. A black powder-coated finish, stainless steel mounting hardware, accent plate, and magnetic drain plug complete the package. Compatible with applicable standard and reverse rotation Dana 30 configurations, this cover is a straightforward upgrade when rebuilding an axle or replacing a factory stamped cover.
Includes:
- (1) Yukon Dana 30 Nodular Iron Differential Cover
- Stainless Steel Cover Bolts
- Stainless Steel Accent Plate
- Magnetic Drain Plug
Important: Designed for traditional Dana 30 front axle housings with the 10-bolt differential cover pattern. Not interchangeable with the newer Jeep JL Dana 30 M186 12-bolt cover. Gasket or sealant and gear oil are not listed as included.

FAQ
Will this Yukon differential cover fit my Jeep Dana 30 front axle?
It fits compatible Dana 30 front axles using the traditional 10-bolt differential cover pattern. Common applications include Jeep Cherokee XJ, Wrangler YJ, Wrangler TJ, and non-Rubicon Wrangler JK models. Verify your axle before ordering, especially if the vehicle has been modified or axle-swapped.
Does this cover work with reverse rotation Dana 30 front axles?
Yes, in compatible reverse rotation Dana 30 applications using the correct 10-bolt cover pattern. Reverse rotation refers to the ring and pinion gear design, so cover fitment still depends on the housing and mounting pattern.
Will this cover fit a Jeep Wrangler JL Dana 30 M186 axle?
No. The newer Jeep JL Dana 30 M186 uses a different 12-bolt differential cover design. This Yukon cover is intended for traditional Dana 30 housings with the 10-bolt mounting pattern.
What is the advantage of a nodular iron differential cover?
Nodular iron provides a rigid, impact-resistant cover that helps protect the differential housing and internal components. Compared with a thin factory-style stamped cover, the thicker construction can provide additional housing support under heavy drivetrain loads and off-road use.
Does this cover include mounting hardware?
Yes. The cover includes stainless steel mounting bolts, a stainless accent plate, and a magnetic drain plug. Gasket or sealant and gear oil are not listed as included.
What does the magnetic drain plug do?
The magnetic drain plug helps collect ferrous metal particles circulating in the differential oil. It also allows the gear oil to be drained without removing the cover, making routine axle service easier.
Is this differential cover a good upgrade for rock crawling?
Yes. A heavy-duty nodular iron cover is a practical upgrade for trail Jeeps and rock crawlers that regularly encounter rocks, ledges, and heavy drivetrain loads. It provides additional protection for the differential housing while retaining bolt-on serviceability.
