Dayco – Serpentine Belt Tensioner; 1 Piece, HD, Built To Outperform And Outlast OE Parts (Part No.89641)

Serpentine Belt Tensioner; 1 Piece, HD, Built To Outperform And Outlast OE Parts

from

$131.99
The Dayco automatic belt tensioner features Dayco’s original, patented flat spring design to provide less operating range variation.

A PTFE string wound within the spring resists abrasion and dampens noise. Dayco’s tensioner is also designed with a heavy-duty cast aluminum spring case and arm, which helps resist cracking and fatigue and offers additional strength, lessening the risk of distortion. Additional premium thermoplastic rubber spring slot plugs and rubber O-ring seals help keep contaminants out and zinc coated mounting bolts resist rust.

Product Features:
  • Endures the toughest conditions while promoting quieter performance and longer life
  • Features a steel pivot tube on specific designs for enhanced stability
  • Built to outperform and outlast competitive OE parts
