12 Valve Cummins Jake Brake


Jun 8, 2022

Can you put an exhaust brake on a 12 valve?

Because you have a 12 valve engine you need to also replace your exhaust springs. Any exhaust brake could (and almost certainly will) create excessive back pressure that could float the factory valve springs risking damage to them from the pistons. via

Does 5.9 Cummins have exhaust brake?

Introducing LoadLeash : The ONLY Engine Brake for 5.9L Cummins Engines. P59 LoadLeash – An Engine Brake designed for the heavy hauler! As the only engine brake available for the class 3-5 truck market, Pacbrake’s P59 LoadLeash provides big-rig engine braking performance when used in tandem with an exhaust brake. via

How does an exhaust brake work?

So, how does an exhaust brake work? Essentially, it works by trapping engine pressure in the exhaust system, which in turn forces the engine to rotate slower (backpressure). Normally, pistons travel upward in their cylinder bore to force spent exhaust gasses out of the engine via the exhaust valve. via

What is a 12v Cummins?

The 12-valve Cummins, officially the Cummins 6BT, is the engine at the bottom of the family tree of diesel engines (at least in pickup trucks). Its simple, straightforward design is a symbol of reliability, solid engineering and tractor-style torque. via

How does Pacbrake LoadLeash work?

The Pacbrake LoadLeash is a bleeder type system. It’s ideal for “small” engines like our 6.7L Cummins. Two braking cycles are achieved. The first braking cycle is accomplished during the exhaust stroke when the piston is pushing the cylinder pressure past the open exhaust valve against the “closed” VGT. via

Does the 2006 Dodge Cummins have an engine brake?

If it’s on a Dodge/Cummins, it’s not an engine brake, it’s an exhaust brake. The closest thing to an engine brake is from Pacbrake but only works on a 6.7 with the VNT turbo, and I believe it is called a weeper brake. via

    What made the Cummins so popular was the fact that its peak power and torque was insanely usable—in fact, the redline is only at 3,000 RPM! The 12-valve was able to get respectable fuel economy while producing torque figures never-before seen in an ordinary pickup truck. via

    When should I use Jake Brake?

    Jake Brakes are commonly used to control the truck speed while descending a steep grade, rather than using the foot brakes, saving wear on the brakes. For most truck driver’s purposes, diesel “engine brake” will be used as a generic term to mean “Jake Brake”. via

    Is it bad to drive with the engine brake on?

    Engine Braking Concerns

    If the engine braking is really aggressive, it can lead to very high engine RPMs that can lead to increased piston ring wear over time. If downshifting is keeping you from using the brakes when you really should, it could potentially cause an accident. via
