The requirements of this shaft seal is often extremely demanding, especially in off-road or motocross application.

TTO offer a high quality fork seal which provides both excellent ride and durability.

The solution these seal provide allow for both off-road and highway use.

The standard TC4 style shaft seal is designed with three lips and one spring. The DC4 type contains three lips and two springs.
