IMO Afco is probably about the best shock for the money. If you have any kind of question about your shocks or want the actual shock dyno sheet for them you can call and they will be more than happy to send them to you. If you do your homework or talk with someone they can actually build you a set with different valving in them. I am going to be using them when I get that far along with the build I am getting ready to start. I have a great relationship with those guys just because of the way they treat their customers and how they keep looking for ways to improve what they have. Strange really doesn't seem to want to move forward. They are good with what they have.
