Complete James Primary Gasket & Seal Kit for Harley-Davidson Sportster 2004–2022

Maintain the performance and aesthetics of your motorcycle with the James Primary Gasket Kit, specifically engineered for 2004 to 2022 Harley-Davidson Sportster (XL) models. Since the introduction of the rubber-mounted engine in 2004, Sportster primary covers require precise sealing to handle the increased vibration and heat. James Gaskets provides an industry-leading solution that surpasses factory specifications, making it the preferred choice for Harley-Davidson maintenance and restoration.

Superior Silicone-Beaded Sealing Technology

The heart of this Sportster primary rebuild kit is the high-performance outer primary gasket. Constructed from premium materials, it features a printed silicone bead that provides a secondary line of defense against oil leaks. This bead is strategically placed to compress into the micro-imperfections of your primary housing and engine case, creating a vacuum-tight seal. Whether you are riding a Sportster 883 Iron or a 1200 Forty-Eight, this gasket prevents the common “weeping” issues associated with lower-quality paper seals.

What is Included in the Kit?

This is a comprehensive JGI-34955-04-K (or KF) series kit, designed to provide every seal you need for a total primary teardown. You won’t have to pause your project to find a missing O-ring. The kit includes:

• Outer Primary Gasket: Premium construction with silicone beading for 2004+ fitment.
• Derby Cover Quad Seal: Specifically designed to prevent leaks at the clutch inspection cover.
• Chain Inspection Cover Gasket: Ensures the top-side adjustment port remains oil-tight.
• Shifter Shaft Seal: High-durability rubber to stop leaks at the gear selector exit.
• Drain Plug O-Ring: A fresh seal for every oil change to prevent annoying drips.

Compatibility & Fitment

This kit is precisely engineered for the Evolution Sportster engine family produced between 2004 and 2022. It fits a wide range of models, including:

• XL883 Series: 883 Custom, Low, SuperLow, Iron, and Roadster.

Why Trust James Gaskets?

For over 40 years, James Gaskets has been the gold standard for American-made Harley seals. Their commitment to “top-quality” means every component in this primary seal kit is tested for heat resistance, chemical stability (against primary oils), and long-term durability. By using a James Gasket, you are protecting your primary chain, clutch assembly, and stator from external contaminants while keeping your transmission fluid where it belongs.

Installation Insights

When installing your new James Primary Gasket, it is vital to clean the mating surfaces of any old residue using a non-marring scraper. Unlike old-fashioned gaskets that required messy RTV silicone, this kit is designed for a dry installation. The pre-applied silicone bead does the hard work for you, ensuring a clean and professional finish that looks as good as it performs.
