Vehicle Fitment

⚠️ Important: This is the right-side (RH) idler pulley for supercharged 3.0L V6 and 5.0L V8 petrol engines – not for naturally aspirated V8 or diesel variants. Fitment varies by model year, production date, and VIN range – verify before ordering.

Signs of Failure

• Belt squealing or chirping – especially at cold start or under load 

• Visible wear or grooves – on the pulley surface 

• Grinding or rumbling noise – from the pulley bearing area 

• Odd or uneven belt wear – cracking, glazing, or fraying 

• Misalignment of pulley – compared to mounting surface 

💡 Continuing to drive with a damaged pulley could destroy the belt if the pulley seizes or breaks apart .

Critical – Verify Your VIN Before Ordering

Idler pulleys are VIN‑, engine‑, and position‑specific. This is the right-side pulley for 3.0L V6 supercharged and 5.0L V8 petrol engines . Provide your VIN – our team confirms exact compatibility before dispatch. We cannot accept returns for misordered parts without VIN verification.

💡 Installation Tip: Professional installation recommended. The idler pulley is an often overlooked maintenance item – in most cases it is recommended to replace it at the same time as the belt tensioner . Inspect the drive belt and tensioner for wear during replacement.
