Gates OE+ Tensioner = True Heavy Duty Performance


Real world tested on Detroit Diesel Series Engines, the DriveAlign® tensioner boasts true heavy duty performance up to 550,000 kilometres. This advanced, drop-in ready solution will save both downtime and money.

When Detroit Diesel found that their 13 and 15 liter engines were showing premature OE tensioner failure, Gates created custom solution. 

Gates DriveAlign® Heavy Duty Tensioner (part number 38667) is designed to replace both the OE tensioners on DD13 and DD15 engines. This is an advanced, OE replacement Heavy Duty Tensioner applied to Freightliner Cascadia, Coronado and more.

The Gates DriveAlign® Heavy Duty Tensioner was trialled and tested by having it fitted to a high kilometre fleet. After the vehicles had done more than 400,000kms the tensioner was removed and inspected; results showed excellent durability and reliability. 

Tensioner Design:
The unique design of the 38667 tensioner combines the fan and accessory belt drive tensioners on a common bracket.
