Engine/Transmission (1994 - 1998) Jacobs Exhaust Brake Question

[MAleshire]

Is Jacobs now making an exhaust brake for the second generation Cummins with the auto transmisssion?

For warranty purposes Dodge has approved the Jacobs brake for the 2006 and 2007 5. 9 auto only. FYI It will fit on your 95 auto but is hard on a stock transmission. Shadrach

How is it hard on the stock transmission? Do you have suggestions on a brake?

I'm only 24 hours late in my answer If I remember you have to hook up a switch for the lock up torque convertor to make the brake work properly and this causes strain on the rest of the trans. Someone here will know more as I haven't had any personal experience with this. One of the reasons I am going to run a 5 speed in my truck is so I can use an exhaust brake properly, the other being I want the gear ratios. Shadrach

Oops forgot the suggestions. Jacobs makes a brake for all Dodge/Cummins' I like the Jake one personally but the others have there good points too, like an air compressor for other purposes. The Dodge /Jake model is vacuum operated. The Mopar model is a reboxed Jake. Shadrach

I've had a Pacbrake on mine for over 200K miles with a lockup switch. No problems caused by this setup. I use it all the time.
