Dana 30 Diff Cover

Stop Your Dana 30 From Being the Weakest Link on the Trail

The Dana 30 is the standard front axle on nearly every Jeep from the CJ to the Wrangler JK — millions of rigs rely on it daily. It's a capable axle, but Jeep has always cut corners on the differential cover. The factory stamped steel cover flexes under load, dents easily, and offers zero protection against the rocks and debris.

Our nodular iron Dana 30 differential cover changes that.

Built Specifically for the Dana 30

This cover is precision-cast to fit the Dana 30 axle housing found in Jeep CJs, YJs, TJs, XJs, and JKs. The nodular iron construction is dramatically stiffer than stamped steel — reinforcing ribs add rigidity directly to a known weak point in the Dana 30's design, helping the housing hold its shape under the torsional stress of hard wheeling, heavy loads, and flex-intensive terrain.

The fully machined seal surface mates perfectly to the Dana 30 housing, and machined bolt bosses deliver maximum clamping force so you get a leak-free seal even after repeated thermal cycles on the trail.

A Bonus for Dana 30 Locker Owners

Running an Detroit, or lunchbox locker in your Dana 30 front? The dense nodular iron construction dampens the characteristic clatter those lockers are known for — a side benefit that makes daily driving noticeably quieter.
