These are all the latest updated OEM GM parts offered for your Duramax truck and we have put this package together. For most daily driver trucks, the GM idler and pitman arms are a great choice.

• GM Idler Arm & Support, Part# 84467788
  
• GM Pitman Arm, Part# 84089951

DmaxStore ​Notes:

• It is always a good idea to change the Idler and Pitman arms at the same time. The Idler support (included) should also be replaced if there is more than 50k miles on your current OE style unit.
