The Thumper Fab Extreme Subframe Weld-On Chassis Sub-frame allows you to upgrade & repair your bent, broken, or weak front subframe on the Polaris Ranger chassis. 

Brace yourself for the ONLY front end subframe replacement you'll ever need. When the stock A-arm mounts have got your Ranger bent out of shape, reinforce your ride with a Thumper Fab engineered Extreme Weld-On Chassis Subframe for the Polaris Ranger. (check model fitment tab to verify your year and model)

Don't total-out your Ranger just because your control arm tabs bent! Go from BENT & BROKEN to TOUGH & STOKIN'! (Cutting and welding required.) 

Computer Aided Design

We have spent countless hours and multiple prototype revisions to make sure we have developed a bulletproof replacement for your control arm mounts and beefed up chassis subframe. We designed the subframe to replace all 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. 

  • Excellent for BIG lifted Rangers with oversized tires for dramatically increasing the frame and control arm tab mount strength.
  • Greatly increase frame strength for running lifts, portals, and big wheel and tire packages for mud, rock crawling, or extreme usage.  
  • Box welded construction with tabbed through frame cross members for added torsional rigidity. 
  • CNC Laser Cut and CNC Press Brake for high precision fit and finish
  • Great for replacing the bent control arm mounts or frame area on your stock Ranger as well and getting it back with an even stronger subframe WITHOUT having to replace the entire chassis of your Polaris Ranger!

Insurance denied total, then we found this

This might get long… So bought a used lifted 2019 Northstar 4 door Ranger. Everything was fine until we were driving down a groomed trail and stopped to talk to some random folks. We go to leave, turn the wheel to go slightly right and huge “click” noise. Get out, and the A arm has pulled away from frame and took a huge chunk of the frame with it and the tire is leaning on the machine. Decide to go through insurance because (frame) and they say it’s a manufacturer defect. So have our local motor sports place who have 3 machines sitting there with similar situation reach out to Polaris. They say no, it must have been from a collision. So we’re just sitting here twiddling our thumbs with a totaled Ranger (and it’s payment). Hubby found this on the internet I don’t know where because I’ve never heard of ThumperFab. End up having the motor sports place do the cut and weld and it actually turned out. We took the lift off and replaced some parts also but hopefully this is the answer everyone who has frame damage right there in the front needs. Been on 3 pretty rocky rides and it’s held up and is doing fine. So instead of $14k for a new stock frame and labor, spend $700 and $2500 in labor.
