AC-MTORC Rear Fender Studplate for Harley 1997–2024 — Chrome 1/4-20 Thread Complete Seat Mount Kit

AC-MTORC's chrome rear fender studplate with 1/4-20 threaded seat mount nut assembly secures the seat and protects your fender while restoring OEM-style fit on compatible Harley Touring and Softail models.

This studplate kit replaces worn or missing rear seat mounting hardware and is built to the bolt pattern used on many Harley models from 1997–2024. Machined from durable iron and finished in chrome, the assembly includes the stud plate, seat mounting nuts, and washers so you get a complete replacement that installs without modifying the stock fender or seat.

Will this studplate fit my Harley model?

The AC-MTORC studplate is designed for Harley Touring and Softail families across many model years—refer to the product detail fitment list for exact model matches. It replaces part numbers 59174-99 and 59500519, so if your bike used either of those OEM parts, this kit should align with the same mounting interface.

• Fits Harley Touring and Softail models (see detailed fitment list).
• Replaces OEM parts 59174-99 and 59500519 for direct compatibility.
• Works with seat setups that use a 1/4-20 threaded rear mount.

How durable and corrosion-resistant is the assembly?

The studplate and nuts are made from robust iron and finished in chrome to resist wear and surface corrosion under typical road conditions. Washers protect paint and spread clamping force so the fender and seat retain their original appearance and fit over time.

• Durable iron construction for long-term strength.
• Chrome finish reduces surface rust and matches factory trim.
• Washers included to protect fender paint and stabilize the mount.

What does the package include and how straightforward is installation?

The kit arrives complete with the stud plate, seat mounting nuts, and washers, so you can replace the entire rear seat mount assembly at once. Installation is bolt-on and uses the stock 1/4-20 threaded seat mount holes—basic hand tools and a short service interval are all that’s required for most do-it-yourself installs.

• Complete kit: stud plate, seat mounting nuts, washers included.
• Bolts to OEM mounting points; no cutting or drilling needed for compatible models.
• Simple install with common hand tools—suitable for home mechanics.

Will this change my bike’s appearance or interfere with accessories?

The chrome finish restores a factory-style look and sits flush with the rear fender, so it doesn’t noticeably alter the motorcycle’s silhouette. Because it matches the OEM part numbers and thread size, it should not interfere with most seats or luggage mounts designed for the factory mounting system.

• Chrome styling complements factory trim and accessories.
• Flush fit maintains seat alignment and rider ergonomics.
• Compatible with seats and luggage that use the factory seat mount interface.

Who is this for: Riders who need a reliable replacement or upgrade for damaged or missing rear seat mounting hardware on Harley Touring or Softail machines will benefit most. It's ideal for owners restoring OEM fitment, performing routine maintenance, or swapping seats who want a durable, chrome-finished studplate that uses the original 1/4-20 threaded seat mount.
