Coil over shock question

Does any one know anything about Aldan coil overs? I found a set and was wondering if they would work for my Fairmont. They are single adjustable, 16.5 extended, 11.5 compressed, 5.0 travel with 150 lb 12 inch springs

In my opinion they are worthless nitrogen charged junk, pretty much useless on a drag car. Especially after they loose their nitrogen charge & go dead because their valving relies on the charge to work correctly.

Thanks Dave, I'll pass on them
