I'm kinda new, but eager to learn. I'm in the process of building up my stock 85 K5. I have 10 bolt axles f&r. I plan on putting 35's to start with. Maybe add a body lift later and go bigger. My delima is should I ditch my 10 bolts first. And get something stronger. Or they okay for now. I just dont want to waste money on re-gearing and such. This is not a daily driver. Its going to used to pull a boat in the summer, and crawl the rest of the time. So are these going to crap out on me as soon as I get a lift and start hammering on them? Any suggestions?? And buy the way this forum is great. You guys have really helped me with some problems, Thanks.
