Rotary GM Height Extensions FJ6271YL (two required) are precision-engineered 7-inch wide lift adapters designed specifically for today’s larger and wider GM truck and SUV platforms. Built for shops servicing 2019 and newer Chevrolet and GMC models, this OEM engineered upgrade provides the safe reach, accurate frame engagement, and added lift height needed for vehicles that feature wider front and mid-frame designs.
These Rotary GM truck adapters solve one of the biggest challenges faced by technicians working on late-model GM platforms: standard lift pads often fail to reach the widened front engagement points on vehicles such as the GMC Sierra, Chevrolet Silverado, and large GM SUVs. The Rotary FJ6271YL extensions deliver the correct width and height to ensure secure, slip-resistant contact on designated lift points.
Designed for use with two-post Rotary lifts equipped with flip-up adapters, these GM SUV adapters for lift add a 2 5/8″ height extension, helping technicians safely reach OEM lift points even on vehicles with higher ride heights or complex underbody structures. Because of the wider frame rails used on newer models, two adapters are required per lift to ensure proper front frame support.
Built with heavy-duty, frame-engaging surfaces, these rotary lift truck adapters provide enhanced stability and reach, making them ideal for GM SUVs such as Tahoe, Yukon, Suburban, Yukon XL, and Escalade, as well as 1500-series trucks. The wider 7-inch footprint helps maintain secure contact under load, reducing technician error and improving spotting consistency.
