* Under the rear seat: This is a common location, often accessed by flipping up the seat cushion or removing a section of the seat.
* In a storage compartment under the bed: Some models keep the jack and tools in a compartment under the truck bed, usually accessible from the side.
* Underneath the truck, within the frame: Sometimes it's tucked up inside the frame rail, possibly requiring you to partially reach under the truck to locate it.
To find it, consult your owner's manual. This is the most reliable way to determine the exact location of the jack and any associated tools for your specific Silverado. The manual will also show you how to properly use the jack.
