4933306 Cummins Aftercooler Core
This part is in stock and ready to ship globally.
Offered is our replacement for the 4933306 Cummins Aftercooler Core the 5.9 litre B Series.
This is the 5X13 inch part.
We will be offering the 5X19 inch before summer arrives.
This part is guaranteed for fit and function and carries a 2 year warranty per our terms and conditions.
What do you get?
When you open the box you get:
A tube of lubricant and a brush for application.
Using lubricant makes it easier to install the part and then remove it when doing your regular maintenance.
Two sets of 0-rings (in different diameters).
Smaller which matches the OEM offering plus a larger cross section which may compensate for a worn housing as your system ages.
Pre-installed core stabilizers
Although this is disregarded by some youtube installers these stabilizers are quite important. They perform 2 functions:
1. Reducing vibration at the tube header connection which has the potential of extending the cooler life and keep the area below the header from becoming embrittled.
2. Reducing air bypass at the cooler extents.
Things you should know
This part is made with OEM equivalent materials, design and manufacturing methods
Made in the USA
The fin count is 25FPI as with the OEM
Our headers are made with extruded billet brass
this is better brass material than from other parts of the world where only one substandard brass is allowed for export.
or they use machined cast headers which have a lower density likely leading to a shorter product life
We have decades of know how that have gone into this product.
Some details to note:
There’s a slight configuration change. There’s a slight little button (center) on top that we've left on the header.
It helps us in manufacturing
we guarantee it won’t get in the way.
It allows us to make this part so it is very round, very cylindrical and within a few thousandths of an inch (~0.002") of our dimensional target. It's a great fit to the housing.
This eases installation and later, when servicing, the cylindricity of the part can ease the removal of the unit.
Our product is a drop in replacement for these part numbers:
