Ferrea 02-03 Buell XB9 1.49in OD 1.076 ID Single Valve Springs - Set of 4

With an outer diameter of 1.49 inches and an inner diameter of 1.076 inches, these Ferrea single valve springs are built for specific performance needs on your 2002-2003 Buell XB9. Valve springs are crucial for keeping your engine’s valvetrain in sync, ensuring that valves open and close at the right time relative to the piston's movement. This precise timing is essential for efficient combustion and overall engine health.

Ferrea uses well-built materials to create these springs, aiming for reliable performance. This set includes four springs, designed to replace the stock components and handle the demands of your motorcycle's engine. Proper valve spring function prevents valve float, a condition where the valve doesn't close quickly enough, which can lead to serious engine damage.

When rebuilding or working on the top end of your Buell XB9, choosing the right valve springs is important for maintaining the integrity of the valvetrain. These springs are intended to be a direct replacement for the original parts, simplifying the installation process for those familiar with engine work.
