The 10-bolt gets the job done up to a point.That point is serious wheeling that puts most any axle to the test,and that`s with larger tires.They do just fine for normal use.I never hurt the one in my diesel Suburban with 12.50/35s.Mostly mud on job sites or up eroded muddy logging roads.
The Eaton HO52 is a great rear that I`d leave be as long as it`s working fine,which they have no problem doing when serviced properly,like forever.They are just as strong internally as the 14-bolt full-floater.They are alot lighter and less bulky,too.4.10 is the most highway friendly ratio they came in,which is my gear of choice for my trucks.I run 33"+ tires.A 35" tire on a 4.10 will net you right about 3.73:1.Anything taller,in my book,ain`t a hauler as far as I`m concerned.
It all depends on use and equipment.My`90 Blazer ran 3.08s,12.50/33s,10-bolt/12-bolt and did great.I had a manual 4spd so I could use granny when towing.3.08s is like having full-time o/d in my book.Just a note:I sold it @193,000 with the original clutch and tall gears are tough on a clutch...not that I toed that much with it.But the bigger tired simulate hauling to a degree.Never hurt that 10-bolt either.
