Fitment and Installation Notes

• Includes new longer u-bolts and hardware. Will require longer shocks if you don't already have them.
• Notes: 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 the ReadyLIFT kit's standard U-bolts are too short, ReadyLIFT recommends locally sourcing custom U-bolts built to each truck's specifications.
• Longer shocks will be required if you do not currently already have longer rear shocks.
