RockJock Driveshaft Carrier Bearing Spacer

2018–2026 Jeep Gladiator

RJ-151402-101

Overview:

The RockJock Billet Aluminum Driveshaft Carrier Bearing Spacer is a precision-engineered solution designed specifically for lifted Jeep Gladiator models from 2018 through 2026. When lifting your Gladiator, driveline angles can become excessively steep, leading to premature wear and potential driveline vibrations. This spacer addresses that issue by lowering the driveshaft carrier bearing, effectively reducing driveline angles and improving overall drivetrain reliability.

Crafted for Jeep Gladiator enthusiasts who demand durability and performance from their off-road builds, this spacer ensures your drivetrain components maintain optimal alignment even with suspension modifications. It is an essential upgrade for anyone running a lifted Gladiator who wants to protect their driveshaft and carrier bearing from undue stress.

Key Features:

Engineered for durability and ease of installation, the RockJock Driveshaft Carrier Bearing Spacer offers the following benefits:

• Precision-machined billet aluminum construction for superior strength and corrosion resistance
• Designed to lower the rear driveshaft carrier bearing, reducing driveline angles in lifted Gladiators
• Includes longer, high-quality hardware for secure and proper installation
• Direct fitment for a wide range of Jeep Gladiator trims and model years (2018–2026)
• Helps extend the life of your driveshaft and carrier bearing by minimizing vibration and wear
• Maintains factory mounting points for a straightforward, bolt-on upgrade
• Compatible with popular Gladiator trims including Rubicon, Mojave, Overland, Sport, and more

Construction & Design:

This spacer is crafted from billet aluminum, chosen for its excellent strength-to-weight ratio and resistance to corrosion in harsh off-road environments. The billet machining process ensures tight tolerances and a perfect fit between the factory carrier bearing and the frame. The design maintains factory mounting geometry while providing the necessary offset to lower the carrier bearing position.

RockJock’s attention to detail extends to the included hardware, which consists of longer bolts engineered to securely fasten the spacer and bearing assembly without compromising structural integrity. This combination of premium materials and precise engineering guarantees a durable, long-lasting upgrade for your Gladiator’s driveline.

Installation & Fitment:

Installation is straightforward for anyone with basic mechanical skills and standard hand tools. The spacer fits directly between the factory driveshaft carrier bearing and the frame, requiring the removal of the original hardware and replacement with the supplied longer bolts. No modifications to the vehicle’s frame or driveshaft are necessary.

This product is compatible with Jeep Gladiator models from 2018 through 2026, including the 80th Anniversary, Altitude, Freedom, High Altitude, Launch Edition, Mojave, Mojave X, Overland, Rubicon, Rubicon X, Sport, Sport S, Texas Trail, Willys, and Willys Sport trims. It is specifically designed for lifted Gladiators where driveline angle correction is critical.

What's Included:

• Billet aluminum driveshaft carrier bearing spacer
• New, longer mounting hardware for installation

Ideal For:

This spacer is ideal for Jeep Gladiator owners who have installed a suspension lift and want to maintain proper driveline geometry. It is perfect for off-road enthusiasts, daily drivers with lifted Gladiators, and anyone looking to prevent driveline vibrations and premature component wear caused by steep driveline angles.
