exhaust brakes and gear vendors ?
 

I'm new to the world of diesels I have a 95powerstroke does anybody have any information on exhaust brakes I've been looking into it say wh at you think is the best 1 . does anybody have the gear vendor I have a 5 speed manual transmission is it worth getting looking for opinions

If you decide to get both you have to turn the exhaust brake is off when using the overdrive, or else you will destroy the gear vendors. The GV tech informed me of that.

how will it destroy it? a exhaust brake doesn't slow the engine that drastically.
