Why a Complete Fastener Kit Matters

Most LS builds:

• Reuse torque-to-yield bolts (bad idea)
• Mix hardware grades (worse idea)
• End up with inconsistent torque and sealing

ARP Fixes All of That:

• Matched hardware across the entire engine
• High-strength alloy fasteners throughout
• 12-point head design for better access and torque accuracy
• Reusable bolts—ditch torque-to-yield for good

Translation: your engine is assembled like it should’ve been from the factory… if the factory cared about performance.

It’s easy to assemble a show-quality engine when you use ARP’s handy Engine & Accessory Fastener Kit. Virtually the whole lot you want comes completely organized in one convenient package (no wish to care for twelve different part numbers) More importantly, each fastener is superior in strength to the OEM bolts, and also significantly better than hardware grades (even Grade 8).

If you’re rebuilding an LS and not upgrading hardware… you’re just planning your next teardown.

You have a number of two premium quality materials and finishes.Traditionalists will appreciate the strength and functionality of ARP’s heat-treated 8740 Chrome Moly steel alloy bolts, which feature a black oxide finish.Those who desire a dazzling engine will undoubtedly prefer fasteners made of ARP’s specially alloyed Stainless 300 material, which has the additional advantage of being virtually impervious to rust and corrosion.

What’s Included with the ARP 534-9705 LS complete engine fastener kit

This complete engine fastener kit typically covers:

• Cylinder head bolts
• Main cap bolts
• Timing cover bolts
• Oil pan bolts
• Water pump bolts
• Intake manifold bolts
• Other critical engine fasteners

(Exact contents may vary slightly, but it’s a full-coverage kit.)

The stainless steel is polished to reach a brilliant luster, and provides a distinctive, maintenance-free environment.Each and every kit has a dozen different type fasteners, all neatly organized and labeled in protective vacuum-wrapped packages. Both materials are nominally rated at 170,000 psi tensile strength and come in both hex and 12-point heads.

Key Features

• 12-point head design for precise torque and clearance
• High-strength ARP alloy construction
• Black oxide finish for corrosion resistance
• Complete matched fastener set
• Reusable hardware throughout

Performance Benefits

• Ensures consistent clamping force across all engine components
• Improves gasket sealing and durability
• Supports high-horsepower and boosted LS builds
• Eliminates weak links from mixed or worn hardware

No more guessing which bolt is about to fail next.

Please note that these kits are designed for carbureted engines. Newer EFI applications may require the purchase of additional fasteners. Engine & Accessory Fastener Kit 12Point Head Material Black Oxide
