Whether you're servicing your factory suspension or installing a compatible aftermarket shock, the mounting hardware deserves the same attention as the rest of your build.
The Imzz Elite ARP Upper Shock Mounting Bolt Kit gives you a coordinated hardware package featuring premium ARP fasteners and our signature billet aluminum finishing detail.

Because the details matter, especially when you're working on your suspension.
ARP fasteners are well known throughout the performance automotive and motorcycle industries for their precision manufacturing and demanding applications.
For this kit, Imzz Elite uses an ARP 12-point bolt selected to meet our application-specific hardware specifications.
The distinctive 12-point head provides a clean, purposeful appearance that complements other ARP hardware throughout your motorcycle.
Whether you're refreshing worn hardware or finishing a custom Softail build, it's a premium detail that belongs alongside the rest of your upgrades.
This isn't just a single replacement bolt.
We've included one of our signature Imzz Elite Billet Aluminum Accent Washers to give the mounting hardware a more finished appearance.
Our billet beauty washers have been a staple on Imzz Elite custom projects for years, from motorcycles to hot rods and sandcars.
Precision-machined in Orange, California, they're designed to complement compatible ARP bolt heads.
The result is a cleaner, more intentional hardware detail.
ARP 12-Point Bolt
Premium hardware for the specified upper shock mounting application.
Spacer Washer
Included as part of the kit's mounting hardware arrangement.
Billet Aluminum Accent Washer
A custom finishing detail that complements the ARP bolt head.
Three components. One coordinated hardware upgrade.
Black Oxide
For riders who prefer a dark, understated hardware finish.
Black Oxide complements black suspension components, dark chassis details, and blacked-out Harley builds.
Black Oxide is a conversion finish applied to steel fasteners. It requires routine care to maintain its appearance and reduce corrosion.
Stainless Steel
For riders who prefer a bright, clean hardware finish.
Stainless Steel complements polished, machined, and other stainless components throughout your motorcycle.
Stainless steel offers inherent corrosion resistance, although routine cleaning is still recommended.
Choose the finish that best suits your build.
Designed for the upper rear shock mounting location on compatible Harley-Davidson Milwaukee-Eight Softail models.
Important Fitment Information
This product is intended for the M8 Softail platform, not the older Twin Cam Softail suspension configuration.
Exact compatibility may depend on:
Motorcycle model and year
Factory or aftermarket rear shock configuration
Upper shock mounting arrangement
Required mounting hardware dimensions
Available clearance around the mounting location
Confirm compatibility with your motorcycle and suspension setup before ordering.
Do not assume this kit fits every Harley-Davidson Softail model or every aftermarket shock.
Already upgrading your rear suspension?
The upper shock mounting hardware is a detail worth considering while the suspension is being serviced.
This kit is a natural addition to compatible:
Rear shock replacements
Performance suspension installations
Factory suspension maintenance
Custom Softail builds
ARP hardware upgrades
Chassis hardware refreshes
A clean suspension setup deserves a clean hardware finish.
Upper shock mounting hardware is a critical suspension component.
Correct fitment and installation are essential.
Before installing:
Confirm the bolt, spacer washer, and accent washer are correct for your motorcycle and shock configuration.
Follow the applicable Harley-Davidson and shock manufacturer's service instructions.
Support the motorcycle and suspension as required by the service procedure.
Install the supplied components in the correct orientation and arrangement.
Use the specified tightening procedure and torque value for the exact hardware application.
Verify that the shock mounting assembly is secure and that suspension movement is unobstructed.
Inspect the installation before riding.
Do not substitute an assumed torque value or washer arrangement.
Incorrect suspension hardware installation can cause component damage or loss of control.
If you're unfamiliar with motorcycle suspension service, have the installation performed by a qualified technician.
Black Oxide is a conversion coating applied to steel hardware.
It provides a dark appearance but is not rust-proof.
A light protective oil coating is commonly used after finishing to help protect the surface.
Why Are My Black Oxide Bolts Oily?
A light oil film is normal and helps protect the finish during storage and handling.
Can Black Oxide Bolts Rust?
Yes.
Moisture, road grime, washing, and neglected maintenance can contribute to oxidation and rust.
Don't Wait for Rust to Develop.
Regular maintenance helps preserve the appearance of your hardware.
Clean and dry the hardware after washing your motorcycle
Remove road grime and moisture promptly
Apply a light protective oil where appropriate. We love Silikroil!
Wipe exposed hardware regularly with a treated cloth
Inspect more frequently in wet or humid conditions
Avoid applying oil to brake components or other surfaces where contamination could create a safety issue.
Preventative maintenance is much easier than trying to restore the finish after corrosion has developed.

Carry the same ARP 12-point appearance throughout your motorcycle with compatible Imzz Elite hardware kits for:

Matching hardware can help tie together the finishing details of your build.
At Imzz Elite, ARP hardware is one of our specialties.
Since 1996, we've been helping Harley-Davidson riders build, maintain, and customize their motorcycles with carefully selected performance parts and hardware.
Our ARP kits are developed around specific motorcycle applications rather than simply replacing bolts for appearance alone.
We select hardware to our specifications and package the components needed for the intended application.
The M8 Softail Upper Shock Mounting Bolt Kit is another example of that approach.
