Description

The Powertrax Grip Pro Traction System (GT248730) is a helical gear limited-slip differential for GM 12-bolt truck axles with 30 splines and a 3.73-up gear ratio. It improves traction by transferring power to the wheel with the most grip, suitable for street performance and light-duty off-road. It replaces the open differential carrier, offering smooth, quiet operation without harsh engagement. It's known for durability and ease of installation, typically requiring no special tools or setup changes.
