Updated the Vin straight from insurance website. Looking to add an exhaust brake on my 2001 Damon escaper 3979 with a 350 HP idc Cummins. Did not come with one from factory. ( tyler wilson, 08/22/2023 )

Have you visually confirmed there is no exhaust brake? We checked with Spartan and they are telling us your RV came equipped from the factory with a Jacobs exhaust brake.

I have a 2001 Damon Escaper 3979 with a 350 horsepower ISC 8.3 Cummins. Has no exhaust brake from the factory. I want to add one. Do you know what kit or part number I need to order? ( Tyler Wilson, 08/22/2023 )

The VIN you provided is not working for us, can you please check and confirm?

The Pacbrake on my '99 American Tradition with a Cummins 8.3L ISC has failed. The exhaust brake serial number is 022625 and I cannot see a part number. It's 4" pipe.
Which replacement Pacbrake part number along with the clamps part number should I order? Do I need anything else?
Thank you!

If your brake is mounted on a 90 degree elbow, you would want part# C40107 and clamps C10310 & C11350. If it mounts directly to the back of the turbo, you would want part # C40108 and clamps C11355 & C11350.

Last year when leaving Florida after a month stay the exhaust brake stuck closed causing the loss of power/boost. By the time I was able to get off the road a lot of heat built up in the engine area. When the heat dispersed the clapper on the exhaust brake closed. I did not use it the rest of the way home. I was able to lube the brake after returning home and it seems to actuate properly now. It does feel that the brake does not slow the coach as well as it used to. Can you offer ideas as to why it does not slow the coach down like it used to? Did the overheating of the brake/engine area cause something to warp or a gasket to become distorted that I can replace instead of the entire exhaust brake. Any help will be appreciated. Thanks ( Thomas Rouillard, 11/12/2022 )

The heat could have damaged the exhaust manifold gasket which would decrease the performance of the exhaust brake.
