Installation. Installation requires moderate skill, including some drilling and wire splicing. Professional installation is recommended to ensure precise fitment and reliable operation. Vehicle-specific installation instructions and mounting hardware are included to assist with the process.
Warranty. Covered by a five-year limited warranty that protects against defects in materials and workmanship when installed according to the provided instructions.
Application. Designed specifically to fit 2020 through 2023 Sierra 3500 HD Double Cab and Crew Cab models, assuring exact fit and optimal function for these vehicles.
