Construction & Design:

The kit features a bare 9-inch rear housing constructed from high-strength materials to endure the rigors of high horsepower applications. The front mount is precision-engineered to bolt directly to the original 5-bolt pinion support, ensuring a seamless integration with your vehicle’s drivetrain. Driveshaft Shop’s custom billet CV joints incorporate fully REM polished internals for reduced friction and enhanced durability, while the Porsche style 930 inner CV uses a larger center bar—the strongest tested component on the market—proven in record-breaking IRS race cars.

All CV shafts are meticulously balanced on a state-of-the-art 9500 RPM balancer, addressing the unique vibration challenges posed by modern unibody muscle cars. This attention to detail guarantees smooth operation and longevity under extreme torque loads.

Installation & Fitment:

Installation is a straightforward bolt-in process requiring no major modifications, making it accessible for experienced enthusiasts and professional installers alike. The rear housing bolts directly into place, replacing your factory rear end with a durable 9-inch unit designed to be the last rear end upgrade your Grand Cherokee SRT8 will ever need—unless you choose to swap gears for different track conditions.

Note that this kit is engineered for use with Strange 5-bolt pinion center sections. If you plan to use a center section from another manufacturer, modifications may be necessary, and fitment cannot be guaranteed.
