## Product's reviews:
- Seal - Right product at a good price with fast delivery.
- Bushing order for down equipment - Great Service, Prompt delivery!
- 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.
- Prompt & great service - As usual MRO Supply team are quick in shipping the ordered parts correctly without any delay.. Will shop online again confidently knowing they offer very good and prompt service!




## FAQ:

- How should I store a Dodge gearbox over the off-season?: Dodge's guidance for seasonal or long-term storage: fill the unit completely full of oil, plug the breather, and coat the seal surfaces with cosmoline or grease. Restore the correct operating oil level and breather before returning the unit to service.


- 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.


- Why do Dodge gearboxes cost more than import brands?: Reliability is the product. Dodge TXT and Torque-Arm II reducers go through 15 quality checks before shipping, and Dodge manufactures its own bearings at its North Carolina roller-bearing and Tennessee ball-bearing plants rather than buying them in. You're paying for uptime.
