Frame Stiffeners For Jeep XJ

We have been making these for more than 10 years and there are over 1,500 pairs in use! Perfect for a Crawler or Jeepspeed! This is our version of the Cherokee Unirail Reinforcement plates. They are certainly as well made as any of the rest but have some very definite improvements to boot! Where the others stop the Cap at the floor creating a very long stress riser on the very weak floorboards, ours continue 1" onto the floor itself. Spreading out the load further and increasing the lifespan of the body. Another of the unique ways these are made is the front and rear risers follow the Unirail into the wheelwells. The rear doesn't need too much but the front goes up 9" into the front fender at the angle of the rail after it turns into the well. When you install these it is the perfect time to create your own longarm kit and we have the brackets for it! If you are sticking with stock, either cutoff the leading 9" or remove and replace your link bracket after you install the rails. The last thing these do that others have chosen to ignore is make adding a skidplate easy. Weld the flat area around the crossmember and then use a jack to custom fit the bends.

This should be the first step

I did light trails with my '01 XJ with 3" lift on 31"s and would hear the unibody creak and moan whenever it would flex. I put these on as well as the front stiffeners and you can't even tell it's a unibody anymore. Definitely worth the buy and install time. It should be the very first thing you do to your XJ.

The fit is perfect. The function is stellar. I wouldn't build another xj without doing this first. Strong foundation with minimal added weight. And they look Sah-wee-tah!
