Travel or stroke? The works shock only has 4 1/2 inches of stroke just like the fox airs. Yes 450 for both but the works is close to 900.But you can buy 2 fox airs for less then 1 works and works performance quality is not as good there is not much more travel with both these shocks over stock but the ride is waaaaay better. If you want better shocks save up and buy them you wont find used works shock for cheaper then 400 bucks then they will need rebuilding.
