Jeep XJ/MJ 4 Bolt Steering Box Conversion




This is the Jeep XJ Cherokee and MJ Comanche steering box upgrade reinforcement. If “far from perfect” is how you’d describe the Jeep XJ/MJ steering, we at TNT Customs would agree with you!  One feature that we have grown especially fond of is the steering box that has only three mounting ears.  What we were lucky enough to experience (on the trail) was the failure of said mounting ears.  We can’t tell you why so many jeeps were built with them, but we can tell you how to upgrade the steering box on your Jeep Cherokee XJ or Comanche MJ so you’re never left stranded.
