Jeep Grand Cherokee ZJ Frame Stiffeners

Jeep Grand Cherokee ZJ Frame Stiffeners




The Jeep Grand Cherokee ZJ was originally designed to do the mall crawl in questionable weather, not to climb a 30 foot waterfall.  As a result, the unibody will flex and eventually get bent out of shape, causing issues with door-fitment, rear hatch alignment, creaking and groaning while driving, cracking and many other less-than-pleasant issues, thus leading to the invention of TNT’s frame stiffeners. We have sold thousands of chassis stiffeners to Jeep Cherokee XJ and Grand Cherokee ZJ owners.

Using our frame stiffeners by themselves, you can establish a chassis sub-frame where there never has been one.
