Dodge(Jacobs) Exhaust Brake

[FDNYMOPARGUY]

Anybody out there have the dealer supplied exhaust brake? It's manufactured by Jacobs. I was curious how well it holds up against the competition. Also, it's the only one on the market "authorized" by Dodge and won't void the warranty(when dealer installed of course).

Use the search feature on Jacobs. You'll get a lot to read!



No problems, just praise on my E-brake by Jacobs. Thirty months and 62,000 miles (self-installed).

no problems and mine was dealer installed just for that reason.

than added a [ bought from bd ]on /off switch to the 6 speed floor shift stick ,much more convient than useing the on/off dash mounted switch

 

[FDNYMOPARGUY]

Was the dash switch included with the brake? If so, did you wire the shifter switch inline with the dash or just remove it altogether? And does the Jacob brake have a provision for an EGT probe?

jake brake

wired inline to factory switch [yellow wire i think?]

no jake doesnt have provison, had to drill the maniflod check www.tstproducts.com i think you will find instructions on how to do it in addtion i also put a magnet right next to the drill bit so when i pulled thdrill bit out the shavings stayed on the drill bit

have fun

My understanding is that the dealer-installed brake is also covered by the factory warranty. I am pretty sure that none of the exhaust brakes will void the warranry, as long as they're installed properly. I think they're all pretty good products, from what I've read.



I'd have to guess that they're all about the same on top end braking. The engine can only take so much back-pressure. I keep seeing the phrase, "60# valve springs", so I assume they all generate about that much back-pressure at speed.



I think the ones that use an orifice in the butterfly to limit back-pressure won't work as well at lower engine speeds as the BD, which is why I bought it. BD uses an offset butterfly and springs in the piston to relieve the pressure, so I think it's going to do a better job of regulating back pressure independently of engine speed. As I recall, the US Gear one uses two butterflies to achieve the same result.



To me, one of the plusses of the Jacobs is the ECM wiring method. I used that method when I installed my BD, and I'm much happier than I think I would be with a microswitch on the foot-feed. I also used Bob V's Super Shifter, which puts the exhaust brake control on my shift knob, along with a 2WL switch. Highly recommended.



There is a short delay with ECM operation of the brake, which allows us to shift without the brake energizing between gears. It also lets the driveline pre-load before brake operation.



The BD has provision for an exhaust temperature probe and for a pressure gauge.



Wish I could have told you more about the Jacobs. I've never met anyone that's not happy with theirs.

There are two places on the ebrake to drill and tap for a post turbo EGT probe. Here is a picture of my ebrake after drilling the hole.
