Act drive actually gave a slight weight loss to the sled over the chain case because of the missing drive components, one of the major down falls of not having the chain case is that you can not install reverse to the act drive also from my experience it is easier to work on chain case than DD. However some have said that the act, once set up properly is faster than a chain case, That I'm not sure with though. But as said before you still have a fast sled.

DJ, your sled still rocks man, don't get frustrated with it. No matter what sled you have, your always going to want something more, or something different.

I have a chaincase, so I don't know much about DD. But from what I hear, changing your secondary to a 10.4 will make a huge difference.

Chaincase will get you reverse, but they will both go forward, so have fun with what you've got!

I would not say that a chain case drive is better......Faster yes. But better. No. Chain cases have alot of slop not noticable but it does exist. If a planatery gear set (act drive) was such a bad idea enginers for automotive transmissions would not be using them. I would not go and sell your sled because you have a act drive. I can promise you, you will never brake that act drive. I personally would rather have a gear drive then a chain drive anyday.

for racing applications chain case is much better due to its simplicity of chainging gears, more noisey yes but but look at it this way gears are cheeper to replace and easyer to change, it is noisier but if noise gave me performance id go with it, as of weight im guna say its lighter than diamond drive just my opinion

There's nothin wrong with a Diamond Drive. In the '05 brochure, AC claims the DD shaves 11 lbs. off the sled. I would say that's mostly from the jackshaft you don't need. When clutched properly Diamond Drives work well. I think I'm gonna give this set up a try this year.
