Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
Interlock buttons can serve as locking pins for doors, ramps, or safety devices, preventing unintended movement. Given its classification under Hardware & Fasteners, it may be a spring-loaded button that locks two parts together until pressed. Replacement is necessary when the button becomes worn, corroded, or fails to lock securely. Because the exact part could not be identified in industry catalogs, verify dimensions and function against your original equipment before purchase.
