Description
ACCEL 140040 is a single high-energy ignition SuperCoil for certain early GM LS-based truck engines. Its internal winding and heat-resistant epoxy construction are intended to improve spark delivery while using the appropriate factory-style mounting and electrical interface.
Key specifications
- Sold individually: one ignition coil, not an eight-coil set
- Yellow ACCEL housing with high-temperature epoxy encapsulation
- Designed for selected GM truck LS 4.8L, 5.3L and 6.0L engine families
- Manufacturer lists compatibility with specific 1999–2006 truck/van engines and codes
- Direct-replacement style for the matching Delco/Delphi-type coil
Applications and selection
- 1999–2006 GM light- and heavy-duty truck applications with the listed 4.8L, 5.3L or 6.0L LS ignition-coil style
- Engine codes and the exact original coil body/connector must match the manufacturer application
Important installation notes
GM used several ignition-coil housings in the same era. Confirm physical coil style, bracket and connector against the original coil before ordering; the engine displacement alone does not prove fitment.
Manufacturer: ACCEL Ignition; Manufacturer part number: 140040
