Mopar 68384503AA Transfer Case Extension for 18-26 Jeep Wrangler JL & Gladiator JT

Mopar Transfer Case Extension (68384503AA) is an OEM replacement housing component engineered to restore proper transfer case assembly fit and durability on compatible Jeep applications. Designed for select 2018 to 2026 Jeep Wrangler and Gladiator JT models, this transfer case extension helps ensure the drivetrain remains protected and properly supported, which is critical for reliable 4x4 performance both on-road and off.

Built to Mopar factory specifications, the extension features a rigid, cast-metal construction with reinforced ribbing for strength and long-term resistance to vibration and load. Using a genuine Mopar part helps maintain original equipment alignment and sealing surfaces, reducing the risk of improper fit that can occur with non-OE alternatives.

Ideal for repairs after damage, wear, or teardown service, this component is intended to integrate with the existing transfer case system as originally designed. For best results, confirm compatibility by part number and vehicle configuration before ordering.
