The Halo Locker has 2 main advantages over the Can-Am smart-lok differential.
First, it is a 100% positive lock and cannot slip when engaged. The Smart-lok has clutches that slip and wear out.
Second, the Halo Locker is more durable and much better able withstand the abuse, and stress created by larger than stock tires, horsepower upgrades, and extreme riding. It has a 40% larger internal differential gear set and uses larger diameter axle input shafts for superior strength.
