The GM Adapter FJ6257KIT is a critical accessory for any professional automotive shop servicing modern fleets. As vehicle engineering evolves, so must your equipment. General Motors introduced a wider frame design on their 2019+ Chevrolet Silverado 1500 and GMC Sierra 1500 trucks, creating a lifting challenge for standard lift pads. This Forward Lift GM Adapter—which doubles as a fully compatible Rotary Lift GM Adapter—solves that problem instantly.
Why You Need the GM Adapter FJ6257KIT
Standard lift adapters are often too narrow to safely engage the front pick-up points of the “Next Gen” GM trucks. Using improper adapters can lead to instability, frame damage, or catastrophic slippage. The GM Adapter FJ6257KIT features a specifically widened 7-inch platform with “ears” or raised edges that cup the frame rail, ensuring a positive lock.
By installing this GM Adapter for lift arms, you ensure that every lift is stable, level, and safe. It is the only way to adhere to “Fixed Right First Time” standards when working on these specific vehicles.
Universal Compatibility: Forward Lift & Rotary Lift
One of the most common questions we receive is regarding brand compatibility. While often labeled as a Forward Lift part, the GM Adapter FJ6257KIT is a genuine Vertical Service Group (VSG) component. This means it is designed to work seamlessly across multiple premium lift brands that share engineering standards.
