4" Exhaust brakes?

[Archive]

Are Jacobs brakes, BD brakes, and PacBrakes available in a 4" size for use with an Hx40 turbo ?

BD makes a good one, air or vacuum actuated. They don't sell electrically actuated 4" because the underneath location would cause problems with it shorting out, etc. I don't know about the other two brands you mentioned.

I've seen several of the 4" BD remote mount, vacuum operated exhaust brakes that you inquired about (both had the Holset HX40 Super Turbo on their Rams). After talking to the respective owners, they both seemed to be quite satified with their decisions, stating they would purchase the same brake if they had it to do all over again.

The pacbrake you ordered thru the group pucase deal will work great with that and you saved almost $200 under retail price!!
