What are Truck Door Strikers?
Door strikers are the latching point for the mechanism to lock onto when the door is closed. Every time the door is opened and closed the latch and striker make contact, and over the years the striker and latch will wear. Given enough time and use the striker or latch will eventually need replacement.
Door strikers are a hardened bolt with a custom-sized shoulder and head. The length and diameter of the shoulder are sized to work with the latch and fit tightly. Depending on the truck, the sizing may be metric or standard. Some replacements can be found by measurement if an OEM number is not available for cross-reference. There are three important measurements to consider when replacing a door striker.
