If you tow at all, I highly recommend an exhaust brake. Hell, even if you don't tow I suggest an exhaust brake.

It's recommended to upgrade your exhaust valve springs to 60lbs or more if you install one and I've heard both ways on wether or not its good or bad on the engine. I've rode in a 07 2500 cummins with a utility bed loaded down to the max with a welder, compressor and other such equipment and it made a big difference when it was on and off; saves the brakes too. Only down side that I've heard is a mechanic at the dealer told us that if you don't run with it on alot it will stick up with carbon and jam sometimes open sometimes closed

I'm pretty sure they're 35lbs stock but dont quote me on that. yea i feel you on the add ons theyre addicting as heck. if you're going to do the cam and exhaust springs id look into upgrading the intake springs too while your in there.

The stock 12V 5.9 came with 30# valve springs, to get the most retarding you want to install the 60# valve springs, Also if the truck is an automatic you are going to need a Transmission lock up controller.

Here's another comment in favor of the exhaust brake.... Aside from "it works", and "saves the wheel-brakes", somebody a long time ago, in a webthread far, far away said that its use would keep the exhaust valves from cooling too rapidly and warping on the downhill side after a high-temperature climb. I have no idea if that's a real concern, but, it sounded plausible to me.

geddy's uncle's Sig:My truck: "Tiny" '98 QC LB 2500 12-valve, G56, hybridized t-case (long story).
Son's truck: "Da Beast" '90 RamCharger, 12-valve from a '92, NV4500/NP205, matched D-60s, RhinoCoat inside and out.
Daughter's baby beast: '06 Liberty CRD, nearly bone-stock except for an oil-mist trap between the "hockey puck" and the turbine inlet's airhorn

Default Is a used jake brake worth anything?

I have a 95 dodge 2500 with a jake brake and do not pull any large loads I am thinking of taking the jake brake off. Is there any interest in used jake brakes and what could I get for one?
