XJ Chassis Channel Reinforcement

XJ Chassis Channel Reinforcement
We have now made these for more than 8 years and there are over 1,000 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 way 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. They are 3/16" thick and come as a pair.

Reviewer: Nick Taylor (Ellensburg, WA)

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.

These are the best frame stiffeners ever they went on really easy and fit tight to the factory unibody.

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!

Reviewer: Andrew Maust (Albuquerque, NM)

The XJ has proven to be a good daily driver over the past 12 years. Never really went off road as I was unsure how a stock XJ would hold up. Put a small lift on and swear I could feel the frame flex. Called ruffstuff who really helped me out identifying the right parts for my Jeep. With the frame stiffeners they installed easy enough for a first time weld project. After words we took the jeep out for a test drive. On the road the jeep felt more solid almost like a new car. Since we were close to the mesa we decided to take a detour taking the jeep off road. Never really been that far off road but it worked without any complaints. Had the XJ fully flexed out and still able to open the doors as easy as if we were on flat ground. Only wish I had the time and funds for a long arm conversion at the same time. Regardless this is still a worth wile upgrade for any Jeep.
