All Balls tests these seals on a dyno to validate durability and uses directional ribs and dual sealing lips so installation is straightforward and oil stays contained.

• Check OEM references listed on the product page against your bike

How do directional ribs and dual sealing lips help during installation?

Directional ribs provide positive orientation, making it easier to install the seal in the correct direction without guesswork. Dual sealing lips are positioned to face the fork oil and increase retention, which helps reduce leaks when the fork is assembled and in use. These features are intended to simplify replacement and improve sealing performance compared with basic single-lip designs.

• Directional ribs indicate correct seal orientation for quicker installs
• Dual sealing lips set toward oil reduce the risk of leaks
• Designed to fit into OEM fork assemblies without modification

How durable are these aftermarket seals compared with OEM parts?

All Balls reports dyno testing that demonstrates these seals can last three to four times longer than some OEM seals under test conditions. While on-bike longevity depends on riding conditions, maintenance, and fork condition, the engineered materials and testing aim to extend service intervals. The kit is sold as a 100% new aftermarket replacement built to meet OEM specifications.

• Dyno-tested for improved life versus typical OEM seals
• Constructed as a new aftermarket replacement to OEM specs
• Warranty-protected for one year against manufacturing defects
