Before You Install
Suspension modification notice. Installing this product modifies the suspension of your vehicle. A modified vehicle may handle differently than it did from the factory. Reduced speeds and different driving technique may be required, particularly in sharp turns and abrupt maneuvers. Always wear seat belts.
Alignment. Your vehicle will likely require an alignment after installation, at additional cost.
Headlamp aim. Check and adjust headlamp aim after installation.
Driver assistance systems. If your truck has camera- or radar-based safety systems, they may need to be re-aimed or recalibrated by a dealer after a ride-height change.
Read the instructions all the way through before starting. Installation by a qualified technician is recommended. Some modifications may not be legal in every state — check your local laws.
