Keep power flowing to your starter, ignition, and accessory circuits with the Standard Ignition Ignition Switch (US-254, also written US254). This ignition starter switch controls the electrical circuits that crank the starter and energize the ignition and accessory systems when you turn the key. It's a direct-fit replacement for the 1992-1995 Chevrolet G10 and G20, 1992-1996 Chevrolet G30, 1996 Chevrolet Express 1500, 2500 and 3500, 1993 and 1995 Chevrolet GP3500, 1992-1995 GMC G1500 and G2500, 1992-1996 GMC G3500, and 1996 GMC Savana 1500, 2500 and 3500 — see the Buyer's Guide tab for the full list of applications and engines.
- Copper alloy conductors: deliver superior electrical conductivity with low resistive losses.
- 100% tested: each switch is verified for both mechanical and electrical switching performance.
- Robust design and high-grade materials: built to meet the stringent demands of today's service professional.
- Quality-controlled build: from componentry to finished product, produced by a global manufacturer of original-equipment ignition products.
If a worn or failed ignition switch is behind a no-crank, intermittent stall, or dead accessory circuit, this replaces it.
