Another vote for G-force. Is it the finest one out there? Probably not. Best value? I think so. They're affordable and I gave the one on my old 350 Warrior Hell. After hitting countless jumps, accidentally rolling the quad off the side of a hill, going mudding twice in one week, swamping it out in a river, and hauling (some) ass (it was a 4-stroke after all. Heavy and slow)...zero problems.
No issues with axle nuts coming loose like on the stocker, either. Yes, I'm rough on my stuff. Meticulous maintenance and an occasional wash-down is usually all it gets. Any other time, I'm out riding like the world's gonna end. Lol.
