Yamaha Grizzly, Kodiak & Big Bear:
Never get stuck in 2WD again.
The Sure 4 manual actuator replaces your electronic one, and a shift lever on your fender or console gives you 2WD, 4WD and diff lock on demand.
Why riders choose it
- No electronics: Takes the faulty electronics out of your 4WD.
- 2WD · 4WD · Diff lock: One lever, clearly marked positions.
- Factory look: Fender-mounted lever looks like it came from the factory.
- Two models: Pick the one that matches your actuator.
Pick your model
Look at the part number on your OEM actuator and choose the matching model when you add to cart.

Good to know: your dash display won’t show 2WD/4WD/diff lock with this kit. The shift lever clearly shows which position you’re in.
Install note: the shift lever mounts to your fender or console, so installing it means drilling a few small mounting holes. Never force the lever: shift slowly, and it slides in when the gears line up.
