Wilbers Zero Friction Progressive Fork Springs G650X Country

Wilbers Zero Friction Progressive Fork Springs have several advantages over linear springs in long travel forks. A Progressive Rate Spring has the advantage of a rising rate resistance to compression. The benefit is that the spring can be soft enough at the start of the travel to offer a "plush" ride, yet be firm enough to resist bottoming at the end of the travel and reduce nose dive under heavy braking.

You will need two quarts of fork oil, 10 wt is recommended.

Although not required, SKF fork seals are highly recommended due to excessive stiction of stock fork seals.

Recommended air chamber is 120mm.
