I am looking at putting 27" muddzillas on my 425 magnum 4x4. Anybody have an opinion on muddzillas? Are they too big for an atv under 500ccs?

 

I have 27's on both my 500's. If I am in deep, it takes all the 500 has to get through (more traction than power). I would definately make the clutch changes to make up for the size difference. I don't know about Mudzillas but the AMS Swamp foxes that I have are great, esp. for the money.

 

what clutch changes??

 

you better use low range alot, and he most likley(just guessing) means a clutch kit of some kind to help w/ those big tires.

Probably talking about a Heelclicker or similar heavier springs.

 

27's on a 425? Original gearing was for what, 25's? Not sure what kinda riding you do, but unless it mostly low speed mud and such... might want to think about consequences.
