When it comes to the legendary 4:1 crawl ratio of a Rubicon, you do not want to gamble on a cheap aftermarket rebuild filled with inferior chains and weak internal components. Choosing a genuine OEM Mopar salvage transfer case ensures you retain the exact heavy-duty case strength, planetary gear precision, and reliable engagement engineered specifically for your JK. Because this is an authentic factory unit removed from an excellent running vehicle, it guarantees a flawless drop-in fitment that will get your rig back on the trails with true factory dependability.
