is it worth it if everything is stock. My buddy just but in a dalton on his 05 and i can beat him stock, so we switched machines and my machine still beat his. Will it really help? I hve the 25" itp mudlites with the littler lugs.

 

If you can spin the tires...the clutch kit really wont improve much. But if you have trouble spinning the tires, then it can help.
Ususaly the weights are lighter, and the motor will rev higher per wheel speed, this helps to keep the motor is the powerband while running bigger or more aggresive tires. But if you have stock size tires, or can easily spin them, then the lighter weights may cause the motor to run into the rev limiter, and actually be counter productive.
Almost all of the clutch kits will reduce top speed, but should enhance acceleration..compared to not haveing the kit and having oversized tires.
If yours is quicker...no need to spend any money. But if you do, a pipe and or freer flowing air filter would do more good than a clutch kit.
