I don't agree with this post at all.
Front end on my grizzly 550 doesn;t walk around, the quad has an excellent power to weight ratio, I have zero issues driving up the ramps to my truck bed even though my truck is higher of the ground than most. Pretty much the same height as an F150 with 4" lift.... again, in over a decade of loading and offloading my machine ..... never an issue.
On last weekends ice fishing trip I was pulling several hundred pounds of gear in 2 ice sleds and at the same time I had TWO grown men of 200lbs plus each riding on the rear rack, plus me driving (160lbs) and no weight on the front rack...... zero issues,
In fact I have never gotten a bouncy or light front end so I call bull####e on that one. Perhaps take your machine in and get the shocks adjusted or replaced in the rear.
When I ordered my grizzly back in 2012 I got them to give me as much ride height as possible so this "should" according to the above poster make it less stable, more tip angle on uphills...... but no. I have oversize rims, oversize ITP mud lite II's and longer suspension travel and fully adjustable shocks so I can adjust them to the conditions or load.
I take no special actions to ride my quad uphills at steep inclines other than to just use common sense and adjust my body weight accordingly.
