Performance and Reliability
The Currie 9-inch rear end platform has long been recognized for its ability to handle increased horsepower while maintaining excellent durability. The CR-GF441TWAB continues that tradition by incorporating premium components designed for both performance and everyday use.
The 4.11:1 ring and pinion ratio provides strong acceleration characteristics while delivering effective power transfer to the rear wheels. This gearing configuration is particularly beneficial for performance-oriented vehicles requiring improved launch capability and enhanced throttle response.
The helical limited-slip differential helps maximize traction by distributing power efficiently between the drive wheels. This improves vehicle stability and performance during acceleration, cornering, and varying road conditions.
The integrated Wilwood Dynapro disc brake system further enhances vehicle control by providing reliable braking performance and improved stopping capability.
Together, these features create a rear axle assembly capable of supporting demanding driving conditions while maintaining long-term dependability.
