GM HEI Ignition Distributor For Chevy/GMC 5.0L 5.7L 7.4L TBI Engines - OEM #1103952 Replacement, Fits 1987-1997 Trucks & Vans

About This Product

Got a mid-80s to late-90s Chevy or GMC truck, van, or Blazer with a 5.0L (305), 5.7L (350), or 7.4L (454) TBI engine? This is a direct replacement HEI distributor. It matches a bunch of OEM part numbers, including 1103952, GM04, GM19, and more. It's the High Energy Ignition (HEI) type with the big cap and built-in coil, common on these trucks. Replaces worn-out distributors causing misfires, hard starts, or no-spark issues. Made with durable materials to handle engine heat and vibration. The HEI design gives a stronger spark than points-style distributors, which can help with performance and fuel efficiency. Covers a huge range of models: Chevy/GMC C/K 1500, 2500, 3500 pickups, Suburbans, Tahoes, Yukons, and even some Cadillacs and Camaros from those years. Always double-check your vehicle's exact year, engine size, and whether it's throttle body injected (TBI) before ordering. A solid, reliable part for keeping your classic GM truck on the road.
