11187 O-ring derby cover

Keeping your primary oil where it belongs is a lot easier with a fresh James Gaskets derby cover o-ring. This specific seal is a high-quality replacement for OEM 11187 and is designed specifically for 1991 to 1993 XL Sportster models. Over time, heat cycles and vibration can cause the original o-ring to flatten or perish, leading to those annoying drips on your garage floor. James Gaskets uses premium materials to ensure a perfect seal every time you pull the cover for a clutch adjustment or oil change. It is a simple, cost-effective way to maintain the integrity of your primary drive and keep your Sportster looking clean and professional.
