Nissan Micra K11 ARP Flywheel Bolts

Upgrade the flywheel fastening hardware on your Nissan Micra K11 with a set of high-strength ARP Flywheel Bolts.

Flywheel bolts are subjected to significant loads during engine operation, making the quality and integrity of the fasteners particularly important on performance, competition and high-RPM engines.

ARP has developed its performance flywheel fasteners as a higher-strength alternative to conventional OEM-style hardware, using premium materials and controlled manufacturing processes to produce a fastener suitable for demanding engine applications.

Why Upgrade the Flywheel Bolts?

The flywheel forms the connection between the engine's crankshaft and clutch assembly and is subjected to considerable rotational forces.

The bolts securing it therefore perform an extremely important job.

This becomes particularly relevant on engines operating with:

• Increased Power & Torque
• Higher Engine Speeds
• Performance Clutches
• Lightweight Flywheels
• Turbocharger Conversions
• Supercharger Conversions
• Frequent Track Use
• Motorsport Applications

ARP flywheel bolts provide a high-strength fastening solution for customers wanting to upgrade this critical hardware during a clutch, flywheel or engine build.

ARP Pro Series

ARP's premium Pro Series Flywheel Bolts are manufactured from high-strength alloy and are rated at approximately:

190,000 PSI

This provides substantial tensile strength for demanding performance applications.

The fasteners are forged from premium alloy material and heat-treated before the threads are rolled and the bolts undergo final machining.

Rolled Threads

ARP manufactures the threads after the material has undergone heat treatment.

Thread rolling forms the thread profile rather than simply cutting material away, helping produce a strong and consistent thread structure suitable for highly loaded fasteners.

12-Point Head Design

The bolts use ARP's compact 12-point head design.

This provides a positive tool engagement while allowing the fastener to remain compact in an area where clearance around the flywheel and clutch assembly can be limited.

Always use a correctly fitting, high-quality socket during installation.

Increased Shank Design

ARP flywheel bolts incorporate a larger-than-standard shank design where applicable.

This is intended to provide additional strength while also helping with accurate location of the flywheel relative to the crankshaft.

Ideal When Changing a Clutch or Flywheel

If the gearbox is already being removed for a clutch or flywheel upgrade, it is an ideal opportunity to inspect and replace critical flywheel fastening hardware.

These bolts are particularly suited to K11s undergoing:

• Performance Clutch Installation
• Lightweight Flywheel Installation
• Engine Rebuilds
• Turbo Conversions
• Supercharger Conversions
• High-RPM Naturally Aspirated Builds
• Track & Competition Preparation

Installation

Flywheel bolts are safety-critical engine fasteners and professional installation is strongly recommended.

Before installation, check:

• Crankshaft Threads
• Flywheel Bolt Holes
• Flywheel Condition
• Flywheel Seating Surface
• Crankshaft Mating Surface
• Bolt Length & Engagement
• Clutch & Flywheel Compatibility

The flywheel and crankshaft mating surfaces should be clean and correctly seated before tightening the fasteners.

⚠️ Follow the Correct ARP Installation Procedure

Do not assume that the original Nissan flywheel bolt torque specification automatically applies to ARP fasteners.

Fastener torque depends on factors including the specific ARP bolt, material, thread size and lubricant being used.

Always follow the installation and torque specifications supplied or specified by ARP for the exact fastener set being installed.

The correct tightening sequence should also be followed.
