MIA's Description

The Rock Hard 4x4 Doublewall Transmission Crossmember is an upgrade designed for Jeep Wrangler JK models with the 3.6L engine, manufactured between 2012 and 2018. It replaces the weaker factory crossmember, offering enhanced protection for the transmission and exhaust system, especially during off-road activities. The double-wall construction provides superior strength and rigidity. It is compatible with both 2-door and 4-door JK models.
