Curtis 13470 User manual

  • Hello! I've reviewed the installation manual for the CURT Trailer Hitch 13470. This manual provides instructions for an easy installation, including trimming the underbody panel and using specific torque settings. The hitch supports up to 3,500 lbs GTW and 5,000 lbs WD. I'm ready to answer any questions you have about the installation process or the product's specifications.
  • What is the weight carrying capacity of the trailer hitch?
    Does the installation of this trailer hitch require drilling?
    What is the torque specification for the M12 bolts?
