## Product's reviews:
- Great customer service - ITEMS WERE IN STOCK, QUICK DELIVERY AND GREAT CUSTOMER SERVICE.
- Bearring - Perfect
- Parts - great stock, ships quick
- Bearings - Order arrived on time, could have been packed a little tighter as the boxes the bearings came in were tore up. All is good as i used all of them instead of leaving them set in inventory.




## FAQ:

- How does Dodge warranty evaluation work if a product fails?: Failed units go to Dodge's US plants for evaluation — about a week in transit plus one to two weeks of analysis, and you get the findings either way. Warranty covers workmanship and material defects; failures caused by the application (lubrication, installation) fall to the customer, but the failure analysis tells you the root cause so it doesn't repeat.
