Description
If you’re running a 1/2 ton GM truck and need the flexibility to switch between full-time and part-time 4WD engagement, this conversion kit delivers a straightforward mechanical solution that reduces drivetrain wear and improves fuel efficiency. The OEM-style locking hubs give you manual control over front axle engagement, eliminating unnecessary spinning components when you’re on pavement. This is essential if you tow regularly, run highway miles, or want to extend the lifespan of your transfer case and front differential.
