just wondering if anybody has any clutching tips for a 96 ext 580. still has factory 6 tower clutch.
it engages at 3800 rpm, i was also wondering what i had to change to get it to 4500. i heard that a polaris spring was the way to go, please let me know

Try the yellow green spring. If I remember right that is what I used....that or the HPE orange. You might have to change weights to get it to pull. I used the A-52 mods that were used in the 96 ZR 580 ETT.
