Important Notes: Single Cab configuration has not been validated for fitment and drivability by ReadyLIFT. Some GM HD trucks equipped with Tow Package may require custom-length U-bolts purchased separately. Custom U-bolt length may vary by vehicle application—if standard U-bolts are too short, ReadyLIFT recommends locally sourcing custom U-bolts built to your truck's specifications.
