Sunluway 5.3L LS Ignition Coil Bracket Kit — D581/D514A/D510C Fit, Aluminium & Steel, 8-Position

Sunluway's 5.3L LS ignition coil bracket kit securely mounts eight ignition coils to LS-series valve covers for a direct-fit, durable replacement solution.

This precision kit is made to replace worn or missing coil mounting hardware on 5.3L LS engines and compatible LS-family platforms. Built from high-performance aluminum alloy and stamped steel, the brackets and included fasteners provide corrosion resistance and heat tolerance that stand up to under-hood conditions. The set is engineered to accept D581-style coils and matches OE mounting points so you can restore secure coil positioning and consistent spark plug connection.

Will these brackets fit my LS engine and coils?

Yes — the Sunluway kit is engineered for a wide range of GM LS-series engines and D581-format ignition coils. It matches factory valve-cover mount points and accommodates common LS swaps with similar coil geometry.

• Compatible with LS1, LS2, LS3, LQ4, LQ9, LS6, L92, L99, L33 and related 5.3L platforms.
• Designed around D581 / D514A / D510C coil footprints for secure seating.
• Direct-replacement mounting locations to simplify installation.

How durable and heat-resistant are these brackets?

These brackets combine aluminum alloy and steel components chosen for strength and corrosion resistance. The materials and factory finishing help the mounts resist the high temperatures and chemical exposure found in engine bays.

• High-performance aluminum alloy for thermal stability and light weight.
• Steel hardware where higher shear strength is needed.
• Surface treatments to reduce rust and maintain fit over time.

What comes in the kit and how easy is installation?

The package contains eight bracket pieces plus the matching bolts and mounting hardware to fasten all coils to both valve covers. Installation is straightforward for anyone comfortable removing valve-cover fasteners and repositioning coils; no special tools are required beyond common hand tools.

• Complete hardware for mounting eight coils across two valve covers.
• Simple bolt-on fitment using existing coil mounting holes.
• Note: long-body aftermarket coils may require additional spacers (not included).

Can these be used on modified engines or LS swap projects?

Absolutely — the kit is commonly used in LS-swap applications and engine modifications where original coil mounts are missing or incompatible. Its OE-style mounting points make it a reliable choice for custom installs.

• Works well in swap projects where valve covers retain factory coil bosses.
• Secure mounting reduces coil movement and connector strain in custom setups.
• Great for restoring functionality after valve-cover replacement or modification.

Who is this for: This Sunluway ignition coil bracket kit is aimed at DIY mechanics, professional technicians, and builders doing LS-series maintenance, restorations, or swaps who need a dependable set of coil mounts. If you have D581-style coils and want a long-lasting, corrosion-resistant mounting solution that mimics original fitment, this kit provides the parts and hardware to mount all eight coils cleanly and securely.
