SKF KITG-45M-HD Heavy-Duty Fork Seal Kit 45mm Marzocchi

The SKF KITG-45M-HD is a Heavy-Duty (H-D) fork seal kit engineered for 45mm Marzocchi motorcycle forks. Designed to deliver superior sealing performance while significantly reducing friction, this kit is an ideal upgrade for riders who demand reliable suspension performance—especially in extreme or muddy riding conditions.

Kit Contents:

• One (1) oil seal — features a dual-lip design with oil seal lip geometry tailored specifically to the individual fork application
• One (1) dust/dirt scraper (wiper seal) — acts as the first line of defense against dirt and contamination entering the fork internals

Note: This kit services a single fork leg. Two kits are required for a complete fork rebuild.

Key Features:

• 20% reduction in friction for improved feel, smoothness, and rider comfort
• Dual-lip sealing design on both oil and dust seals for maximum protection
• Self-lubricating compound construction for consistent, low-friction operation
• Enhanced water and dirt exclusion to extend seal and fork component life
• Reduced air suction and wear for consistent hydraulic performance at factory-set levels
• UV-resistant materials maintain performance and integrity over time
• Recommended for extreme mud riding conditions

SKF recommends replacing the oil seal and dirt scraper simultaneously—a worn scraper can significantly shorten oil seal life and reduce overall fork effectiveness. The KITG-45M-HD Heavy-Duty kit is purpose-built for high-performance and off-road applications where standard seals fall short.
