Crane Axle Dana 30 Chromoly Differential Cover
CAD30C
The Crane Axle Dana 30 Diff Cover is built for Jeep owners who need real protection without unnecessary bulk. Designed with an aggressive low-profile shape, this cover helps maintain clearance around steering and suspension components while giving your Dana 30 axle the strength to handle hard hits, rocks, and repeated abuse on the trail. The lipless design helps prevent the cover from catching on obstacles, making it a smart upgrade for crawlers, trail rigs, and street-driven Jeeps that still see serious off-road use.
Cast from 8620 chromoly steel and machined in house, this heavy duty Dana 30 diff cover is made to deliver a precise fit and long-term durability. The recessed bolt land helps protect the hardware from impact damage, keeping the cover secured even in rough conditions. Each cover ships as unfinished steel and includes Grade 8 twelve-point hardware and a fill plug. Proudly cast and machined in the USA, this is a heavy duty Dana 30 cover built for performance and protection.

Tech Insight
A differential cover is more than just a cap for your axle housing. On a Dana 30 that sees real trail use, the cover is one of the first points of contact with rocks and ledges. A lipless, low-profile design helps the axle slide across obstacles instead of hanging up, which can make a real difference when climbing or dragging the front axle through tight terrain.
The choice of 8620 chromoly steel matters too. Compared to mild steel, 8620 offers a stronger material structure with a hard outer surface and a more ductile core. That combination helps the cover resist impact damage while still handling repeated abuse without becoming brittle.
