This is the complete 3.90 ratio limited slip carrier for the 230mm rear axle, the unit that comes standard behind the six-speed manual Scat Pack and SRT cars. The ZF limited slip design sends torque to the wheel with grip instead of spinning one tire, which is what makes it a popular upgrade on an R/T as well as the correct replacement for a worn or noisy original.

Carrier Specifications:

• Fits 2015-2023 Dodge Challenger and Charger with the 230mm rear axle, sales code DR4.
• 3.90 axle ratio with a 9.05 in. ring gear.
• ZF limited slip differential design.
• Supersedes the 05038703 series through 05038703AJ.
• A core charge applies. Ratio and axle size must match the vehicle, since speedometer calibration depends on it.
