Sunluway LS ignition coil bracket kit — 8-piece D581/D514A mounts for 5.3L LS engines, aluminum alloy & hardware

Sunluway’s 8-piece ignition coil bracket kit secures D581/D514A/D510C coils to LS-series valve covers for a clean, reliable swap on 5.3L and related engines.

This bracket set is engineered to replace OEM coil mounts when converting or repairing LS-family engines (LS1, LS2, LS3, LS6, L92, L99, L33, LQ4, LQ9 and others) using D581-type ignition coils. Manufactured from aluminum alloy and steel, the kit includes all the hardware needed to mount eight coils across two valve covers, offering corrosion resistance and heat tolerance suitable for engine-bay conditions.

Will these brackets fit my LS-series valve covers and coil type?

Yes — the Sunluway brackets are designed to precisely position D581-series ignition coils on common LS valve covers used in 5.3L and similar swaps. They match the dimensions and mounting points for many aftermarket and OE-style valve covers, reducing modification time.

• Compatible with D581, D514A, D510C coil families.
• Fits many LS1, LS2, LS3, LS6, LQ4/LQ9 and L92/L99 valve covers.
• Includes hardware to mount eight coils across two covers.
• May require separate spacers for extra-long coils (not included).

How durable are these mounts under engine heat and vibration?

Sunluway uses high-performance aluminum alloy and steel components to withstand high temperatures and resist corrosion typical in engine compartments. The construction and finish minimize metal fatigue and maintain secure attachment under normal driving and light-performance use.

• Aluminum alloy brackets for heat tolerance and light weight.
• Steel fasteners where strength is required.
• Corrosion-resistant finishes to protect against humidity and road salts.
• Designed for stable performance under vibration loads.

How simple is installation — what’s included and what might I need?

The kit ships with all mounting brackets and necessary hardware for installing eight coils on two valve covers, making the basic install straightforward for anyone familiar with LS ignition systems. If your ignition coils are longer than standard D581 units, you’ll need to source additional spacers to achieve proper clearance; spacers are not supplied in the set.

• Complete set of brackets for eight coils and mounting screws included.
• Basic hand tools and a torque wrench recommended for accurate installation.
• Extra spacers required for long-length coil designs (sold separately).
• Installation compatible with standard valve cover gasket and coil boot clearances.

What support and warranty come with the Sunluway kit?

Sunluway backs the bracket kit with a 12-month warranty and customer support to address fitment questions or defects. If you experience issues, contact the seller for troubleshooting, replacement parts, or warranty service.

• 12-month limited warranty included.
• Customer support available for fitment and installation guidance.
• Returns or replacements processed per warranty terms.
• Quality control checks performed before shipment.

Who this is for: This bracket set is aimed at mechanics, DIY enthusiasts, and performance builders performing LS-series swaps or replacing worn coil mounts on 5.3L and related engines. It’s ideal for anyone installing D581-style coils who wants a corrosion-resistant, OEM-compatible mounting solution that saves installation time. If you use long-profile coils, plan to buy spacers separately; otherwise the Sunluway kit provides a ready-to-install, durable mounting system for eight coils across two valve covers.
