The kit supports vehicles with stock suspension setups as well as those lifted up to 5 inches, making it versatile for a range of builds.

Adjustability allows for fine-tuning of the pinion angle, which is critical for preventing driveline vibrations and ensuring smooth power delivery. No major modifications are required, and the kit is engineered to integrate seamlessly with factory mounting points.
