Not really modified when it is a direct swap.... is it??
The 8.25, in my book, is much better of a axle then the D35. I friend of mine has been running my old 8.25 under his rig for at least a year with it lincon locked turning 35's without any issues. He beats on it hard.. not easy on the go pedal at all. He is big on the rocks and still has not broke anything. I have seen many D35's break under the strain he has put the 8.25 under.
