I'll just answer the question. I have an 85 x-cab 3rz with 37's and 4.88s. It runs great. I wouldn't want 5.29s on the highway. Only time I wanted a little more juice was when I swapped to beadlocks... A ton more rotating mass and it dogged her down a little. It's purely up to you. Light build 4.88s are great.
