SKF KITB-45S HD Fork Seal Kit Showa 45mm Black

The SKF KITB-45S is a heavy-duty fork seal kit engineered for Showa 45mm front forks. Built on SKF's advanced self-lubricating compound technology, this kit delivers measurable performance improvements over OEM seals by reducing friction, extending seal life, and providing superior protection against contaminants.

What's Included:

• One (1) oil seal — inside diameter: 45mm, outside diameter: 57mm, thickness: 11.2mm
• One (1) dust/wiper seal (dirt scraper) — inside diameter: 45mm, outside diameter: 57.6mm, thickness: 5.5mm

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

Key Features:

• 20% reduction in friction — maintains constant, low friction for more precise fork movement over small bumps and under light loads
• Improved feel and smoothness — virtually eliminates stick-slip (stiction) for a more responsive ride
• Extended seal life — self-lubricating compound significantly increases durability compared to standard OEM seals
• Enhanced water and dirt protection — dual-seal design keeps contaminants out and oil in
• Reduced wear and air suction — helps maintain fork oil integrity over time
• UV resistant — both seals maintain low, constant friction even with UV exposure
• Compatible with OE and aftermarket oils — broad oil compatibility ensures versatile application
• Recommended for extreme mud riding conditions — engineered for demanding off-road environments

SKF recommends replacing the oil seal and dust scraper simultaneously. A worn dust scraper accelerates oil seal degradation and reduces overall fork performance. The black compound designation (KITB) identifies this as SKF's standard high-performance formula for Showa fork applications.
