I’ve been researching on this:

Polaris Signature Lift Kit for Sportsman and Scrambler

And I have some questions…
I don’t do mud, and I don’t plan on getting bigger tires (currently running 26" Bighorns)

What I do need is the extra clearance. I do a lot of desert trail riding, and a lot of river-bed rock crawling, which is what I need the most clearance for.

Do I need to upgrade the axles, even though I would not be doing any mudding or bigger tires?

Would I need to put spacers to keep stability?

I aready hot a QSC Clutch kit.

Thanks in advance if anybody can help.
