Built to outperform and outlast competitive OE parts. Dayco tensioners endure the toughest conditions while promoting quieter performance and longer life for all applications that feature a serpentine belt drive. Unlike tensioners with coil springs, they feature our original, patented flat spring design to provide less operating range variation and reduce the risk of premature accessory bearing failure due to high tension.
Premium design features include:
- Heavy-duty cast aluminum spring case and arm to help resist cracking and fatigue
- A steel pivot tube on specific designs for enhanced stability
- Thermoplastic rubber spring slot plugs and rubber O-ring seals to help keep contaminants out
- Zinc coated mounting bolts that resist rust
