Ultimax 144-4740U4 PRO Snowmobile Drive Belt by Timken

The Ultimax 144-4740U4 PRO is a snowmobile drive belt from Ultimax by Timken, designed for modern mid-power snowmobiles. Its thicker cross section puts more surface area in contact with the clutch, which means less slippage over a broader speed range and quicker acceleration.

Key Features:

• Thicker cross section: more contact surface with the clutch for reduced slippage
• Cog design: dissipates heat and aids flexibility, so the belt runs cooler for enhanced performance and longer belt life
• Top and bottom cogs: give greater cord support for more power capability without sacrificing flexibility
• Fiber-loaded rubber: designed to grip the clutches and keep gripping over the life of the belt
• Aramid cord: strong and stable for zero stretch and maximum tensile strength
• Fifth-generation design: built on decades of refinement, using modern manufacturing methods to reduce variability and eliminate classic failure modes
• Consistent dimensions: produced with processes that reduce dimensional variation, held to tighter tolerances than OE belts
• OE-matched size: cord length and width match OE so your sled shifts like new

Specifications:

• Outside circumference: 48-1/8 in.
• Top width: 1-31/64 in.

Built with high-strength materials to handle every riding style, from ditch-banging to deep powder to trail riding.
