Has anyone added a exhaust brake to a 650 with a 5.9 cummins. If so what brand and did you have to change the ehaust valve springs?

Thanks Don

I have a 95 F-800 with a 12 valve 5.9L. I ordered my exhaust brake kit right from the Cummins dealer. I had 20# exhaust valve springs from the factory, I had to install 60#. The exhaust valves came with the kit. The exhaust brake is extremely effective even with the Allison AT 545 automatic transmission.
