Good To Know

Q: How do I know if this set fits my truck? A: Match your engine displacement and coil style against the listing details for 4.8L, 5.3L, 6.0L, LS1, or LS3 applications. Verify the coil connector and mounting style before ordering.

Q: Can I replace just one coil or should I do the whole set? A: A single failed coil can be replaced on its own, but many owners replace coils and plugs together for even ignition performance. Follow your service manual for torque and gap specifications.

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