10.25 Sterling is far better because it's a full float axle...the other one is a semi-floater
The 10.25 came in semi-float as well. I would not say the full-float is far better installed in a Ranger. A Ranger isn't heavy enough to hurt either axle. You aren't using these for weight carrying, which is the advantage of a full-float axle. You just need the shafts and gears, which are the same dimensions.
