So I have a brute force 750 which I have now chipped it, lifted 2inches and put 30 inch tires on it.Well I made it about 14 k down the trail and tried sun heavy chewing well click click click the cv shafts didn't stand up.So the rest of the day I followed and broke trail in two wheel drive..The BRUTE performed really well against the other Polaris and grizzly quad while in 2 wheel..So I'm looking for the strongest axle package and I here gorilla axles are the way to go.Any other suggestions would be appreciated thanks an happy riding.
