LCWRGS Ignition Coil Pack Set for 5.3L V8 Trucks — 8-Pack Direct-Fit High-Energy Replacement

If your Silverado, Tahoe, Suburban, Avalanche, Sierra or Yukon with the 5.3L V8 is showing misfires, sluggish throttle response, or a check-engine light tied to ignition faults, this complete set of eight coil packs gives you a direct-fit replacement. Built to meet or exceed original equipment design, these coils use high-conductivity copper windings and durable epoxy insulation for stable performance under highway and towing loads.

How will these coil packs affect engine performance?

Replacing worn ignition coils can restore consistent spark delivery across cylinders, improving throttle response, reducing misfires and helping the engine run more smoothly. LCWRGS coils are engineered to provide slightly higher energy output than aging OE units, which helps combustion stability.

• Delivers up to ~15% more ignition energy versus some original coils for improved combustion.
• Reduces cylinder misfires that cause rough idle and power loss.
• Helps clear ignition-related diagnostic trouble codes when faulty coils are the root cause.

Which vehicles and part numbers are these coils compatible with?

This set is designed to be a direct fit for a wide range of GM models equipped with the 5.3L V8 across model years. They replace several common OE and aftermarket reference numbers so installation is straightforward for technicians or experienced owners.

• Compatible models include 2007–2013 Chevy Silverado/Avalanche/Tahoe/Suburban and 2007–2014 GMC Sierra/Yukon 5.3L V8.
• Also fits select 2005–2008 GMC Envoy 5.3L engines in applicable configurations.
• Replaces part numbers UF413, 12570616, D510C, 12611424, and related OEM references.

What are the construction and durability features of LCWRGS coils?

These coils combine robust internal windings and high-dielectric epoxy to resist heat, vibration and moisture, which are common stressors in under-hood environments. The components are selected to reproduce OE fit and function while offering long service life under normal use.

• High-conductivity copper winding for dependable electrical transfer.
• Epoxy potting and silicone boots to resist arcing and environmental exposure.
• Manufactured to meet or surpass OE electrical and dimensional specifications.

How easy is installation and what’s included in the package?

Each coil is designed for a direct swap with the original unit—no modifications required—so replacement is typically quick when you have basic hand tools. You receive a full set to change every cylinder at once, which prevents blending old and new coil performance characteristics.

• Package contains a full set of 8 coil packs for complete ignition replacement.
• Direct OEM-style design for plug-and-play installation onto compatible engines.
• Backed by a 24-month warranty and customer support for fitment or defect concerns.

Who is this for: This LCWRGS set is intended for owners and mechanics working on GM trucks and SUVs with the 5.3L V8 who need a full ignition coil replacement — whether troubleshooting persistent misfires, replacing age-related failures, or performing preventative maintenance. It’s well suited for daily drivers, fleet vehicles and light-towing trucks seeking an OE-fit replacement that balances reliability and value without complicated reprogramming.
