3406E/C15 .003" Undersized Spacer Plate
Usually Ships in 24 to 48 Hours
3406E/C15 .003'' undersized plate is recommended when your liner protrusions are too low to use the standard thickness plate. We use this plate 90% of the time, if we are changing just the head with the engine having several miles on it and we are not replacing liners. Liners tend to sink a couple thousandths after the engine has been built for sometime and this spacer plate will help get your protrusions back within spec.
We recommend using a new spacer plate with each overhaul. Lots of people decide to clean up the old spacer plate and reuse it but this is not a good idea. On the 3406E/C15 liner protrusion is crucial to making the head gasket last as long as the rest of the engine. If your liner protrusions are off just .0015 of an inch and then you use a old wore out spacer plate that may be off that same amount we guarantee you'll be back into the engine in a very short time. Don't let the cost of a spacer plate keep you from rebuilding the engine the right way. Once and done is cheaper than the time or labor to pull that head off again.
