HD springs/Aftermarket suspension

Anything other than Elkas? They are sweet, but a little more than I really need. I wanted some stiffer springs, my rear sags a lot when I am towing my compost spreader.

I have seen springs from quad boss saying 25% stiffer. Is that my best bet?

I've seen the EPI as well, they say 25% too, seem similar priced as quad boss. I saw the highlifter, but thought they might be meant for the highlifter model, or am I wrong its just their name?

Thanks!!

Hi-lifter ones are twice the price of the other brands from what I have seen on their site, but don't seem to be any better? I'm sort of hoping for something with more than 25lbs extra on each corner, but their inch lift might help too...

Does anyone know where I can find info on the OEM springs so I can see if that is a significant jump? And also would help compare quad bosses claims of 25-30% more.


My dusty dawg carrier adds about 80 lbs to the back, plus tongue weight from a trailer...

Right so the HL's is just the name not meant specifically for the Polaris HL model. Generally speaking the HL are stiffer springs. Some have said they are to stuff. But of course it's all dependent on your situation and needs.

For what I'm doing, and the load I'm putting on it, I don't think "too stiff" is currently being made. They might be the fix, stinks they are bright gold tho? Oh well, I'm not doing a beauty show over here I guess. I might have to find some heavier stuff to stash in my front compartment to balance it out at some point, but I can figure that out as I go.

Thank you for your help with this! I really appreciate it.

That's cool!! And you always have the spring tension adjustment collars on the shocks to help balance it all out once you have the HL installed.
