3890 is LONG, like 24 inches extended I think with 9 inches of travel. I've been doing alot of shock research recently and my car (@15.5 inch ride height between shock mounts) needs a 3860 from Afco (6 inches travel, closer to 20" fully extended. They also make a 3870 which is in between the two.

You need to take measurements of your suspension at ride height, with weight in the driver seat, as well as full droop/extension, and go from there.




Topfuel is correct mine are 3860 and my car measures 15 inch ride height.
