Performance and Reliability

The Currie 9 in. Crate Rear End Assemblies CR-GA135TWAB are designed to deliver consistent drivetrain performance in both street and performance driving environments.

A major feature of this assembly is its 3.50:1 ring and pinion ratio. This gearing offers an excellent balance of acceleration and highway cruising efficiency, making it particularly well suited for street-driven vehicles. Drivers benefit from responsive performance without sacrificing comfortable highway operation.

The helical limited-slip differential further enhances performance by improving traction during acceleration and cornering. By distributing torque more effectively between the rear wheels, the differential helps maintain vehicle stability and control under varying driving conditions.

Combined with the strength of the upgraded axle shafts and premium internal components, the CR-GA135TWAB delivers reliable performance for both daily driving and enthusiast applications.

Integrated Wilwood Disc Brake System
