Skyjacker's 1" add-a-leaf assembly is a suspension upgrade intended for Cummins-equipped diesel trucks that need increased load capacity or ride height. The part adapts to existing spring packs to tune ride attitude while retaining predictable handling on and off-road. Skyjacker notes these kits respond well to off-road conditions and may require other parts for a complete installation; hardware and instructions are provided for proper fitment.
