The Xtreme Difference
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.
CNC MACHINED BILLET PULLEYS ARE STRONGER, QUIETER, SMOOTHER AND MAINTAIN STABLE AND FASTER BLADE SPEEDS.*
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.
We increase the size of our pulley bearing to improve bearing life.
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.
High Temp Bearing
Xtreme's special blend of bearing grease is rated more than two times what is required, delivering xtreme bearing life.
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.
Triple Protected Wires
Every Xtreme clutch has an integrated watertight connection with three layers of protection.
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.
Xtreme mower clutches have a replaceable pulley bearing!
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.)
Stainless Steel Rivets
Xtreme clutches use tough stainless steel brake rivets for a long and safe service life.
The Xtreme design uses stainless steel brake rivets instead of weak aluminium or copper rivets. We figure your safety is worth it.
Xtreme "Cool Coil"
The "Xtremely Cool Coil" runs over 20% cooler.
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.
One Clutch, Two Series.
Xtreme’s New Fatboy Series uses top grade bearings and has a massive replaceable Pulley Bearing. The Xtreme High Torque Series Clutch has more torque for those serious enough to tackle the toughest conditions.
