Buddy bought a 97 zl 440 for his girlfriend but doesn't think she'll like the harsh engagment of the clutch at 5000 rpm.
stock yellow-green spring and stock 48.5 gram weights.

is this just the way they are or is there a lower engagment spring thats known to work in this sled ?

Can anyone be more specific with a spring recommendation ? I'm a polaris guy and know all those springs. Cat is alot less familiar to me. thanks in advance.

On my 99 ZL440 I have the green/yellow spring with 46.5 grams and it engages around 3800 to 4000 give or take a few.

I think Polaris springs will work in that clutch. I'm planning on getting a few Polaris springs to try in mine.

That pretty much proves my initial thought. His spring/weight combo shouldn't be kicking in that high.

the polaris springs do work in these clutches, i ran one in my zrt600 and it worked fine.
