This carrier serves as the core of your differential assembly and is required when installing 3.73+ gear ratios in a Dana 30 that originally used a lower split. As an unloaded case, this unit allows builders to choose their preferred spider gears, bearings, and locker solutions. Because it’s a genuine Spicer product, you’re getting OE-grade metallurgy, machining, and reliability — the exact standard Jeep engineers rely on.
Perfect for gear installs, front end rebuilds, or returning a Dana 30 back to stock functionality after damage.
