Hello baldev patel,
please, what peripheral drivers do you have in mind?
KSDK package contains set of peripheral drivers. You can find these drivers under C:\Freescale\KSDK_1.3.0\platform\drivers
KSDK consists of the following runtime software components:

You can test these drivers under concrete board, in case of FRDM-K64F C:\Freescale\KSDK_1.3.0\examples\frdmk64f\driver_examples
or develop your own code based on the demo using KSDK Project Generator Tool (for creating KSDK projects or cloning KSDK projects/demos)
New Kinetis SDK Project Generator is available!
For more information about all these drivers please refer to KSDK v.1.3 API Reference Manual
I hope this helps you.
Best Regards,
Iva
