scram500,

the red spring in the drive pulley allows the belt to engage much faster. For most of us, too fast. If you rock crawl, it would not be a very good idea unless you like laying on you back with an atv on top of youl.

The red spring on this post is the secondary spring for a "360"...

Scram500, actually the red spring delays the engagement. I makes the rpm's increase before the belt engages. Its like reving up a manual clutch atv and "popping" the clutch on it. When it takes off it really takes off. Only places I dont think it belongs is farming and rock crawling. For anything else it is great. Some people dont like the engagement but once you get used to it, its great.
