It is just a replacement spring to replace the weak one presently on the accelerator. The pedal has 2 springs, a torsion spring and an extension spring. There is more than one spring because failure of both would mean WOT conditions and no way to stop the truck. The extension spring on these trucks is wholly worthless, and doesn't resist the user, or supply any real travel feel. By adding 20-30 lb/in to the spring rate, and making it more progressive, a more controlled feel is restored to the operator.
A number of times I have experienced when going over bumps, the weight of your leg causes these engine cycling feedback runups that are just plain irritating. This does away with that, as well as reduces the leg fatique from driving without cruise control. IOW, it allows you to drive with the right foot more at rest, and more resistance keeps those runups reduced. The best way to say it is it makes the truck feel more intelligent, more controlled, if that helps.
I spec'd these springs and have some extras. I will send one out to a few people who want to try it. Just pm me your address. As long as you post your experience with it, there is no cost, unless you want to pay for it.
M: is the medium spring that will be what most people will be happy with long term. Stock tune
H: is for the heavy boot driver, or the bumpy road, or the HOT tune.
They are also sized correctly for the application. The H spring is a little tough to get on, but needlenose pliers usually works unless you are a real lightweight.
Worst case, you need to pull the pedal off, but in most cases, not.
