The plastic engine timing belt tensioner pulley on certain Chrysler vehicles is brittle and will often crack. When it fails, replacing it with an OEM timing belt tensioner could mean the same issues again in the future. This Dorman OE FIX engine timing belt tensioner replaces the plastic pulley with a metal pulley for a more durable replacement. In addition, the bearing on our OE FIX tensioner is much larger than the OEM unit. This allows it to spin slower and increases bearing surface area, which leads to longer life of the part.

Timing Belt Adjuster (Adjuster Only) 420-154 Features:

• Fits 2003-2010 Chrysler; 2003-2011 Dodge
• Upgraded replacement — this engine timing belt tensioner includes an upgraded metal pulley to more reliably replace the failure-prone plastic pulley on specific Chrysler vehicles
• Improved reliability — the bearing on our OE FIX tensioner is much larger than the OEM unit, allowing it to spin slower and the increased bearing surface area leads to longer life of the part
• Repair it once — don't fix a broken engine timing belt tensioner with another failure-prone design just like it; repair it right the first time with this stronger design and don't worry about it again
• Trustworthy quality — backed by team of product experts in the United States and more than a century of automotive experience
