Brace yourself for going BIG! Larger wheels, oversize tires, lifts, and portals all add strain to your stock control arm mounts on the chassis. Reinforce your ride with a Thumper Fab engineered Bolt-On Frame Stiffener for the Polaris Ranger. We set out to design the STRONGEST and EASIEST Frame Stiffener / Gusset Kit to install on the market. Period.
Easy Bolt-On and DOES NOT require cutting or welding.
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.
