im looking to get a exhaust brake for my 04.5 automatic, which one has the best stopping power and is the cheapest. does someone sell a kit with the trans controler and the brake? if i get a sps 62/14/71 will it still mount up to it?
thanks,
matt

 

pacbrake is very nice. More stopping power than the jacobs, and doesn't use the failure prone vaccum pump. No problems clearing the firewall with the pac either.

 

packbrake or bd, they work way better than jake or banks

 

i got the BD brake and it is regulated to 65lbs back pressure to protect the motor from damage.

 

does the pac brake kit come with some sort of trans lock device? does it make the truck downshift like the allisons? if not what kind of box could i get to make the tranny down shift?

 

any one know if the kit comes with the lockup?

 

You should PM Harold-PacBrake on this board as he is a direct factory rep and is SUPER helpful with any questions you have about the brake. I have had mine on for over 70k and it is the best money I have ever spent on the truck.

 

The Pac can be bought right here though the DTR store. I got mine here, Lary took VERY good care of me, unbeatable price actually.
