2023 ruck rear shock gravel/dirt roads

Hey hey, mother-ruckers!! Ok i got a 2023 ruckus and i pretty much commute 15 miles daily… half of those miles are on dirt/rocky/gravel roads. I weigh about 200lbs.
My rear shock isnt doing what i need.
Im looking at this one but havent found out if it’ll fit my ruckus.

I need some info. And… im a public school elementary teacher so budget is important. Im broke as a joke, folks. Lol
