I have a Jacobs in my '03 but it came as part of the new truck deal for 395 bucks and a warranty from Dodge. Its been flawless for over 218k miles. The Jacobs operates from a mechanical vacuum pump that has to be added inline and a long long serpentine belt.
I've had zero issues with this unit.
However if I had a used Dodge/Cummins I would get the Pacbrake as it operates from air pressure from a remote electric air compressor. The air pump can be used for other things.
Remember max braking performance comes at max rpms however the Pac has a bit more power in the lower rpm ranges.
B-D is another good exhaust brake for the Cummins.
The '05 and earlier Dodge/Cummins auto trannies need updating to be exhaust brake compatible. Check with your exhaust brake supplier as they will have the tech facts. If you have the 6 speed manual your in business.
