SuperATV Can-Am Defender Pin Locker Differential

SuperATV Can-Am Defender Pin Locker Front Differential

Replace your Can-Am Defender's stock Visco-Lok front differential with SuperATV's Pin Locker Front Differential and gain true, instant on-demand four-wheel drive. Electronically actuated via a toggle switch, this differential locks both front wheels simultaneously — no waiting for a full wheel rotation like the OEM Visco-Lok clutch pack requires.

Why Upgrade from the Stock Visco-Lok Differential?

Can-Am's factory Visco-Lok differential is a reactive system: it requires at least one full wheel rotation before the clutch pack engages. In technical terrain, that delay costs you momentum and traction. SuperATV's Pin Locker eliminates that lag entirely. Flip the switch and both front wheels receive consistent, locked power for as long as you need it.

• Electronically actuated pin locker mechanism

Frequently Asked Questions

What is a pin locker differential?

A pin locker differential uses electronically actuated pins to mechanically lock both front wheel hubs together, delivering equal torque to both wheels on demand. Unlike a Visco-Lok, it engages instantly with no slip delay.

Will this fit my Can-Am Defender XMR?

No. This differential does NOT fit the Defender XMR. It is also not compatible with machines originally equipped with the Smart Lock Differential.

What is the difference between cast and billet aluminum?

The cast option uses A380 aluminum alloy — a strong, cost-effective choice for most riding conditions. The billet option uses 6061 aluminum alloy, which is machined from a solid block for higher strength and a premium finish, ideal for more demanding use.

Does this come with everything needed for installation?

Yes. The kit includes the pin locker differential, wiring harness, toggle switch, and all required hardware for a complete installation.

Is this differential made in the USA?

Yes. SuperATV's Pin Locker Differential is manufactured in the USA.

What year Defender models are compatible?

Compatible models range from 2016 to present across HD 5, HD 7, HD 8, HD 9, HD 10, and MAX variants. See the full fitment list above for year-specific details.
