Computer Aided Design

We have spent countless hours and multiple prototype revisions to make sure we have developed a kit that will greatly increase strength for your control arm mounts and chassis subframe. We designed the frame stiffener / gusset kit to reinforce weak links and to work with your OEM or Aftermarket Control Arms and Lift Kits with same model year fitment. Using the latest technology in 3D scanning and computer modeling software all aspects of the suspension and chassis geometry have been verified for precision fitment.
