I was just wondering what does each device do? I know the Locker locks your diff so you get true 4 wheel drive but if I buy a locker do I need an unlocker too? I guess the real question is what is an unlocker and do I need one to go with a locker?

 

a locker is manually activated... that means that you turn it on when u need it..( usually a lever u pull )

 

according to the highlifter site, the locker is automatic. A gearless locker. if I can turn it on and off then thats what I'm lookin for. I dont want to put a locker on if its gonna keep the front diff locked ALL THE TIME.

 

Gearless lockers still allow the quad to steer without tons of effort. They use a steel disc assembly instead of gears which still allows differential action in turns.

 

I'm lookin for a setup similar to the grizz. I want a diff lock that I can turn on or off as I choose. First off, does anyone make one for a 04 big bear and if so where can I find it? I see highlifter has a locker and an unlocker. is this what I'm lookin for? or does the locker lock the diff and the unlocker do something totally different? Any help is appreciated.

 

A locker as you already know just locks your diff for true 4wd. The unlockers you're seeing are for atvs that are full time 4wd's. A lot of the Foremans, the Big Bears, Wolverines, etc. do not have selectable 2wd/4wd. The unlocker allows those who own one of these machines to put their machine in to 2wd for a sportier ride. It looks like you own a Big Bear and if you would like the option of 2wd you need the unlocker. Otherwise no.

 

Thanks for the explanation. I dont need an unlocker because my BB has push button 4x4. Like I said I'm lookin for a selectable diff lock. Thanks again.

 

I didn't know Yamaha gave the Big Bear selectable 4wd. My friend has a 2000 Big Bear and it doesn't have the option to select 2wd. I guess that means the Wolverine is Yamahas last machine with full time 4wd then. You're right then, you have absolutely no need for an unlocker kit.

 

I believe the last year they put all time 4x4 in the BB was 02 or 03. so you're buddy just missed it. Again, thanks for everyones help

 

someone said they put a locker on there yfz... is that possible
