Exhaust brake question

Recommended Posts

I am interested in anyone's experience with the upgrade to Pac-Brale model PRXB. Is the improvement worth the cost? All I have read on the subject says the upgrade will result in increased slowing at lower RPM. Please post your opinions and/or personal experience. thanks

Welcome to the FMCA Forum.

I guess I can lead off on this one, as we were one of the very first to upgrade to the PRXB PacBrake. I installed ours 6/30/04.

It works exactly as advertised. The extra valve allows full back pressure to be achieved at much lower RPM than with a standard exhaust brake. I think their advertising says 30% stronger at lower RPM and it feels like every bit of that.

Would not go back to a "regular" brake.
