just bought a new 2004 silverado 3500 chassis cab. it is a 4 x 4 extended cab with locking differential with the lly duramax. i had a new dump bed put on the back and have been hauling 5 tons on a regular basis now and love the truck, the engine and the transmission(i have the manual six speed) i am trying to find an engine brake/jake brake to add on to the engine but am having some difficulty......anybody know where i can find that part??

Uh oh! There goes another warranty!

I do not believe you will ever find a true engine/jake brake for our engines. There are plenty of exhaust brakes which should serve your purpose well. A true engine brake would require a slave cylinder under the valves cover to open the exhaust valves before combustion takes place. This would no be a bolt-on procedure, sorry. http://www.dieselplace.com/forum/smileys/Cool.gif

Cumberland, MD eh?? I know a few guys out in that area. My company built the warrior run plant. I was an engineer on that job.Edited by: Forced Induction

I've been looking too. So far no one has one completed for the variable vane turbo. I had a BD on the '01 but I'm looking at the Banks this time. The unit they have for the Ford is reorted to work very well.

didn't somone on this board melt their valves using an exhaust brake???

I think the jury is still out on what exactly caused the melt down you're referring to, it was a member who's Dad fried a Dmax and it had an exhaust brake. I've not seen a post about what the final determination of the cause was, but GM was saying no warranty because of the exhaust brake....http://www.dieselplace.com/forum/smileys/Ermm.gif

Has anyone heard of any news regarding an exhaust brake for the LLY?
