With machined pulleys, Cool Coil technology, high performance bearings, stainless steel straps and rivets, Xtreme’s Tough Wire Protection System and a replaceable bearing, the Xtreme design is pure performance in every aspect.
Billet pulleys are used on performance applications like NASCAR engines because they don't spread under load like cheap formed pulleys.* When a formed pulley "spreads", the belt sinks deeper into the groove. This lowers the belt speed (like a smaller pulley would) and slows down your blades.
The number one failure of lawnmower clutches is the pulley bearing. Xtreme's new FatBoy Series uses top grade bearings and has a massive replaceable pulley bearing.
Electromagnetic clutches run very hot. High temperatures and vibration are rough on bearings. All Xtreme Series clutches use a highly engineered bearing with a proprietary blend of high temperature grease and harder races to ensure a longer service life.
We use a "watertight" connection at the clutch body instead of a cheap plastic connector with exposed wires. Heat, water, mud, sticks and curbs are no challenge for the Xtreme Wire Protection System.
The pulley bearing takes a serious beating and is almost always the first thing to go bad. For that reason the Xtreme design has a replaceable pulley bearing.(Some models do not have this feature.)
The Xtreme design uses stainless steel brake rivets instead of weak aluminium or copper rivets. We figure your safety is worth it.
Electromagnetic clutches run very hot. Most competitive clutches run around 220 degrees. The Xtreme proprietary composite coil runs 175 degrees. The difference is simple: Less heat = extended life.
