YOSOPP Harley exhaust gasket kit — Fits 1984–2023, 6pc tapered gaskets with 6061 aluminum installer for leak-free seating

YOSOPP’s kit contains a tapered exhaust port gasket set plus an aluminum installer tool to seat seals accurately on compatible Harley-Davidson models from 1984–2023.

If you work on Harley touring, Softail, Sportster, or Dyna motorcycles, the right exhaust gasket and the right tool save time and prevent repeated disassembly. This kit bundles six tapered port gaskets with a 6061 aluminum seal installer, plus disposable nitrile gloves, so you can fit fragile seals squarely into the exhaust port without scratching the head or deforming the gasket. Materials combine stainless steel and graphite for a resilient seal that resists compression set and exhaust-leak symptoms caused by poor seating.

Which Harley models will accept these tapered exhaust gaskets?

This set is designed for a wide range of Harley-Davidson models from 1984 through 2023, including many Touring, Softail, Sportster, and Dyna applications. Specific examples include FLHR Road King (1994–2012), FLHRC Road King Classic (2007–2012), FLHRS Road King Custom (2004–2007), FLHS Electra Glide Sport (1985–1993), and FLHT Electra Glide Standard (1985–2009). Note: V-Rod models are not compatible with this kit.

• Fits numerous Touring, Softail, Sportster, and Dyna models 1984–2023
• Listed compatibility includes several Road King and Electra Glide variants
• Not intended for Harley V-Rod family

How does the installer tool make gasket replacement easier?

The included installer is machined from 6061 aluminum to give a durable, light-weight handle and a precisely tapered end that centers the gasket as it enters the exhaust port. Using the tool prevents pinch-denting the gasket or nicking the cylinder head face, both common causes of exhaust leaks after installation. It also keeps the gasket aligned so mounting studs and flange faces meet evenly when you torque the bolts.

• Aluminum shaft centers gaskets for even seating
• Prevents damage to fragile graphite and stainless layers
• Speeds reassembly by aligning gasket with port and studs

What are the materials and build quality of the gaskets and tool?

The gaskets combine stainless steel reinforcement with a graphite sealing surface to balance strength and conformability under heat cycles. Graphite provides a pliable sealing face that adapts to microscopic irregularities while steel lends structural stability. The installer’s 6061 aluminum construction resists bending, keeps weight low, and stands up to repeated use in a garage environment.

• Stainless steel core for dimensional stability
• Graphite sealing layer for conforming, heat-resistant contact
• 6061 aluminum tool for long-lasting, accurate seating

What’s included and how do I install a tapered port gasket with this kit?

The package contains one aluminum gasket seal installer, six tapered port gaskets, and a pair of nitrile gloves. Installation is straightforward: remove the old gasket, position the new tapered gasket in the port, and use the installer to press it evenly into place, then confirm correct seating before tightening the flange hardware.

• Kit contents: 1 installer tool, 6 tapered gaskets, 1 pair nitrile gloves
• Simple three-step process: remove old gasket, seat new gasket, verify fit
• Avoids gasket distortion and head-face damage during installation

Who is this for: This YOSOPP kit is aimed at DIY mechanics, professional shops, and Harley owners who want a reliable, repeatable method for replacing exhaust port gaskets without risking damage to the head or the gasket itself. If you maintain late-model Touring or classic Electra Glide and Road King variants, or perform routine exhaust work on Softail, Sportster, or Dyna machines, this set provides the parts and tool to finish the job cleanly and quickly.
