send them back with your rear shock and they change the pressure for free.
you can release them... but getting them the same is going to be almost impossible.
be VERY carefull you dont let all the charge out.
Cody did you get a quote on how much they charge to change the lenght??
you might be in the same boat I am.. It might be cheaper to order a new one and sell yours. if yours was 13" I'd be all over it!!
