Function of this part

The turbocharger uses exhaust gas energy to spin a turbine that forces more air into the engine. This extra airflow lets the engine burn fuel more efficiently and make more power without increasing displacement.

Why this part matters

A healthy turbo is critical for power, fuel economy, and keeping exhaust temperatures in check. A failing turbo can lead to low boost, excessive smoke, oil consumption, and in severe cases engine damage.

About the brand

Cummins engine parts are trusted for reliable power in a variety of heavy-duty truck and equipment applications.

Fitment & usage

Used OEM parts are a smart choice for controlling repair costs while still using original-equipment components. Always match the OEM part number(s) listed to your existing part, and consult your service manual, dealer, or technician if you are unsure about fitment.

Note: Because this is a used component, normal signs of wear such as scratches, discoloration, or light surface corrosion may be present. Refer to the product photos and information on Second Truck Parts for the best representation of the part you will receive.

Enables the person to move around while wearing.
These silicon socks look a bit odd at first glance but they work great and best of all, any lotions and oily creams are contained on the inside so you can walk around. They are very soft. I haven't had them long so I can't comment on durability, but they are not made of lightweight material.

Does the job but dangerous to walk with!
Does the job but dangerous to walk with: foot is sliding inside the sock if the foot was treated with cream or lotion prior. It is uncomfortable to sleep with but a necessary hurdle to heal your heels!
