The SKF Dual Compound fork seal kit MTBDUAL-36FN revolutionizes the maintenance of Fox 36 mm forks sold since 2016. The result of over 10 years of SKF expertise in the field of high-performance seals, this patented dual-compound version offers an unmatched combination of extreme smoothness, maximum protection against contaminants, and exceptional longevity. Designed for demanding riders seeking the best riding feel and total reliability in extreme conditions.

Dual Compound Technology: SKF innovation serving performance

• Dual rubber compound: The green dust wiper lip uses an ultra-resistant hardened NBR compound against external aggression, while the red seal lip employs a Super Low Friction elastomer with low friction coefficient, guaranteeing excellent tracking capability of inner tube imperfections.
• High-strength metal insert: New design with reinforced metal insert ensuring optimal support of the seal lips, drastically reducing stiction (breakaway resistance) and increasing durability.
• Self-cleaning coil spring: Mounted on the scraper lip, this open-coil spring effectively prevents intrusion of dirt and water, while maintaining constant pressure for perfect sealing.
• Optimized geometries: New scraper and seal lip shapes developed specifically to maximize inner tube tracking and minimize friction, offering an immediately noticeable sensitivity gain.

Performance and technical benefits

• Minimum 20% friction reduction: Compared to original manufacturer seals, these SKF Dual Compound seals offer an ultra-smooth travel feel, improving fork responsiveness on small bumps and increasing ground traction.
• Enhanced sealing: Extreme protection against water and dust thanks to the dual lip system and self-cleaning spring, preserving bath oil and extending service intervals.
• Exceptional durability: Laboratory tested over 1 million cycles and field validated in motocross for over 50 hours without maintenance, these seals guarantee longevity well above standards.
• Integrated UV protection: The compounds resist ultraviolet rays, preventing premature aging and cracking, even under prolonged sun exposure.
• Extended oil compatibility: Compatible with all original and aftermarket fork oils, including advanced synthetic formulations.

Compatibility and installation

This MTBDUAL-36FN kit is specifically designed for latest generation Fox 36 mm Air forks sold from 2016 onwards, including Float 160/180 mm, 36 Van, 36 Talas and Factory models, as well as the Marzocchi Bomber Z1 (2019-2023). Flangeless version, these seals ensure a tight fit in the lower leg, better resisting internal pressure surges. Installation recommended with a specific installation tool to guarantee perfectly straight positioning and correct depth, avoiding any deformation or crooked installation that would impair performance.

Kit contents and specifications

Each kit includes 2 integrated oil seals (combining oil and dust functions), 2 foam rings pre-impregnated with lubricant to further reduce friction and facilitate installation, as well as the necessary O-rings (exact contents may vary depending on fork model). SKF pre-impregnated foam rings constitute a major innovation: they distribute oil evenly on the inner tubes, ensuring constant lubrication and reducing wear. Manufactured in Italy according to SKF quality standards, these seals are recognizable by their characteristic green color, symbol of excellence in the MTB suspension universe.
