The 03 04 Cobra IRS Rear End Axle Assembly 3.55 Gear is a popular aftermarket upgrade for Mustang Cobra owners who want to improve their car’s handling and performance. Here are some details about this kit:
The kit includes a complete independent rear suspension (IRS) assembly, which replaces the car’s stock solid rear axle. The IRS assembly is designed to improve the car’s handling by allowing each wheel to move independently, reducing unsprung weight, and improving traction.
The 3.55 gear ratio refers to the ratio between the number of teeth on the ring gear and pinion gear. This ratio is designed to provide a good balance between acceleration and top speed.
The kit includes all necessary hardware and instructions for installation. However, some modifications to the car’s drivetrain and suspension may be required to accommodate the IRS assembly.
The IRS assembly features aluminum differential housings, half-shafts, and control arms, which reduce weight and improve strength. The assembly also includes a limited-slip differential, which helps to improve traction and reduce wheel spin.
The kit is designed to be a direct replacement for the stock rear axle assembly and can be installed with basic hand tools. However, some tuning may be required to optimize the car’s performance with the new gear ratio and suspension setup.
Overall, the 03-04 Ford Mustang Cobra IRS Rear End Axle Assembly 3.55 Gear is a popular and effective way to improve the handling and performance of the Mustang Cobra. The IRS assembly provides better traction, improved handling, and reduced weight compared to the stock solid rear axle, while the 3.55 gear ratio provides a good balance between acceleration and top speed.
