Exaust brake 2011 F350

The 2015 has a far stronger exhaust brake than the 2011. The 6r140 is a very beefy unit. If the 68rfe in my truck can handle 180 braking, I'm sure the Ford unit can easily top 200.

Yes it is somewhat 'automatic' to apply the brakes. Just stay in the tow haul mode, then tap the brakes a few times as you decend the hill.

It will not be as strong as a 'jake brake' and the transmission is not really able to handle a full 200 braking horsepower because it is the rear axle pushing the transmission internals that is pushing on the engine, and not the other way around (such as when driving away from a stop sign).

So you get what you have. Anything much stronger in the compression braking department might break the transmission! At least it is much better than what was offered 20 years ago! my buddy's 1985 F-250 would go to idle when going down a hill, and not offer ANY compression braking at all!

Yes, they are stock from 2011 and up. Before 2015, they are adaquate for towing the average size travel trailer. An aftermarket exhaust exhaust brake is now being produced but it looks problematic to me.

You are correct. The exhaust brake is on the weak side, which is why Ford improved it on the 2015 models.
From the superduty website

"Super Duty® continues to innovate with its enhanced Tow/Haul Mode. For 2011, the new Power Stroke® 6.7L diesel and six-speed TorqShift® transmission utilizes seemless engine exhaust braking to improve driving confidence and minimize brake wear. While driving downhill in Tow/Haul Mode and tapping the brake, the combustion process is restricted to help maintain the desired vehicle speed. This big-rig-inspired feature increases towing confidence without wearing down the transmission or heating up the brakes. So when you need extra control coming down that 8% grade towing 20,000 lbs., this new feature on the Power Stroke Diesel gives you that extra driving confidence and safety"

Good luck finding an after market exhaust brake for the 6.7L. Apparently the new emissions systems (DEF/DPF) make it difficult for the after market folks to design a system that can be added to these trucks.
