Specs At A Glance

Good To Know

Q: Do I need to replace the coil and module at the same time? A: They can fail independently, but replacing both together avoids repeat labor if the other part is already worn. Inspect the existing components before deciding.

Q: Will this fit any 4.3L or 5.7L engine? A: Fitment depends on the specific year and model within the 1995-2007 range. Verify your engine code and existing part numbers against DR49 and D577 before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
