Why this tensioner matters

Beyond matching data, the pulley blends robust materials with precise manufacturing. The unit uses high-strength steel and double sealed bearings to resist corrosion and keep rotation smooth through heat and vibration. The exterior is groove-free, which reduces belt wear from friction, while the larger 90 mm diameter helps maintain stable tension across a variety of engine bays.

• OEM-equivalent fit with the listed part numbers for confident compatibility
• 90 mm diameter idler supports stable belt tension and quiet operation
• Groove-free steel design adds strength and reduces belt wear under heat
• Double-sealed bearings protect against dirt and moisture, extending life
• Corrosion resistant construction promotes reliable performance over time

In real world driving, a well matched tensioner can contribute to steadier belt movement and help support the alternator and accessory drive system. While results depend on the overall belt condition and correct installation, the unit is designed to integrate with a broad set of OEM configurations and a wide range of brands.

Installation and maintenance at a glance

• Installation-ready design with clear steps and routing guidance
