Looking to install on a 2004 Ford F750 with a CAT C7. What all would be needed to control it? ( Ethan Fettig, 04/07/2026 )
In addition to the C40106B, you will need a mounting group and control group. For your F750, the mounting group will depend on the configuration of the exhaust pipe coming off the turbo. If you could send us pictures we can identify and let you know which mounting group to order. For the control group, it will use C10319.
Are there gaskets required between the pacbrake and turbo and exhaust side, and if so what are the part numbers needed on the C40106B exhaust brake,
Thank You ( Bill Brainard, 03/03/2025 )
No, there are no gasket used, just the v-band clamps.
Does this item require a core return?
C40106B ( Bill Brainard, 02/26/2025 )
No, it does not. 
I have a 2005 Freightliner M6 chassis with a C7 Cat motor. I would like to add an exhuast brake. What parts do I need to complete the installation? ( ROBERT MATHERLY, 05/02/2024 )
You would need the brake part # C40106B, mounting group part # C11546 and control group part # C20123. PacBrake recommends using the factory Freightliner exhaust brake switch part # A06-37217-056 as well. 
I have a 2007 bluebird vision school bus with a CAT C7 wex series (built in 2006). What parts would I need to install the exhaust brake? Also, does it require any welding or can it all be done with clamps?

Thanks.

We do not have a vehicle specific listing for this but it can be done, we just need additional information. What would be really helpful, are some pictures of the turbo and the exhaust coming off of it. This will determine if the brake can be mounted to the backside of the turbo or if we would need to do an inline brake further back in the exhaust system. We also will need to know if you have on-board air to operate the brake. Last bit of info, we would want to verify you have a 4th generation Allison, if you could get the Allison serial # off the data plate on the side of the transmission we will be able to determine.
