Yea dude those are too short, and I am gonna bag on a few guys on here but yall need to ditch that compression shackle, for high speed stuff you'll see way more benefit from the tension or stock type, you can run a longer shackle it will drop more because of that its better for the spring cause you can run more arch and it also helps the pinion along with reducing the anti squat. So it's a win win win.. Problem for you is it will lower your truck a lot.. If you take those springs and get them rearched to 12-13 inches it will work a lot better and you'll use that shock and then some...
