Ok guys, I need your experience here. Here's the deal '89 Suburban 4" lift, tired 350TBI/700/241, 10b/14bff/3.73. I've all but put my money on the table for 37" Trxus tires. Before I do, tell me if you think I'm doing the wrong thing, and should stick with 35's. Here are my thoughts; I know that I have to regear but I've got 33's now and already want to regear so I don't consider that an added expense. I know the 10bolt is a weak link but my wheeling is mostly mud so I'm hoping to limp it along until I can afford a d60. I really like the idea of avoiding a 6" lift. It is a daily driver in a big crowded city, I like the idea of a lower cog, and I want to avoid driveline issues. I'm not too worried about the trimming as I have rust to remove anyway. I've looked closely at the trimming others have done for 35's and figure I only need to take away another couple of inches. I am concerned with how I will fill in the gap between the inners and outers but I'm sure I'll come up with something. Am I underestimating how easy it will be to stuff those meats under my truck? So what do you think? Am I risking too much trouble and money for a couple of extra inches? I really value the vast experience that is compiled here at CK5.
