Shock Lengths

Ok, I need shocks for my new air ride I'm making. Fronts only for now.



I need 20. 25" ride height, but available to go from 15. 25" under compression to 25. 25" under rebound.



Is there such a thing? Is there a range of lengths shocks come in? Is there a certain ride height to allow travel each way without stressing/bottoming it out?



Thanks!

 

Most major shock companies will have charts showing compressed and extended lengths. . here is an example
