Product Description
Get Your Defender HD8’s Power Back
Larger tires give your Can-Am Defender HD8 the extra clearance and aggressive look you want, but they can also make your machine feel a little sluggish. SuperATV’s Transmission Gear Reduction Kits help bring that lost power back by increasing torque and giving your rig the strength it needs to keep working hard. Choose from 10%, 20%, or 30% reduction options to get the perfect setup for your ride.
10%, 20%, or 30% Reduction
A 10% gear reduction is a great choice if your Can-Am Defender HD8 is running slightly larger tires and you want to keep a factory-like feel. But once you add more weight or step up to bigger tires, a 20% or 30% reduction can give you the extra torque needed to keep your machine moving strong. Whatever your setup looks like, SuperATV has a gear reduction option to match it.
Strength You Can Count On
Your Can-Am Defender HD8 deserves a gear reduction kit that can handle the extra demand of bigger tires and tougher terrain. We build ours from durable 8620 chromoly steel, then heat treat and grind the gears for a precise fit and improved contact pattern. The result? A quieter ride, smoother operation, and long-lasting performance.
