2005 Sportsman 800 EFI bottoming out!!!

I've read numerous threads on here with some GREAT visual descriptions. However, I am still at a loss regarding which spring would be the best. I currently put my 125lbs girlfriend and a storage bag behind me on the quad. I also have a 2" receiver adaptor, 2" receiver riser, and a cargo rack (narrowed to 3') on which I have a medium sized cooler and two 5-Gallon gas tanks. I weigh 230lbs. All in all... a bunch of weight:

Me 230lbs
Girlfriend 25lbs
Storage Bag 40lbs
Receiver(s) 25lbs
Cargo Rack 40lbs
10 Gallons of Gas 60lbs
Medium Sized Cooler (full) 50lbs
TOTAL 470lbs +/- 10%

So my question is... Which of all the types I can recall off the top of my head (EPI, Highlifter, MV7, Progressive, etc) would be the best option for me to install to stiffen the rear end? If/when you respond, please include reasons WHY you suggest the product(s) you suggest. Thank you all very much for your replies.

JT

I appreciate the direction. However, it's been my experience that manufacturers are going to praise their individual products in lieu of suggesting another. I'm really looking for "end-user" feedback.

Follow the link titield Clutch Theory towards the bottom of the original post. It describes cause and effect of varying degrees of issues regarding clutches.

You may have one or "gee" moments during and after reading.

What does the belt and clutch have to do with stiffer suspension springs? He wants to carry a bigger load without the suspension collapsing. Maybe I misread the OP, but that is what I walked away with.

My mistake. I assumed "bottoming out" meant no acceleration despite RPMS. After re-reading, he literally means too much weight.

JRich96... I have already tightened them up. I'm still getting the rub.

I have no problem buying whatever is needed, I just want to buy the right stuff.
