That's what they should look like.
When you lower it on Coilly's you're changing how it sits on the ARB (which is what the Drop links are connected too) when you lower it, you are putting more pressure on this, so you need to make them short to compensate for the lowering
What I said could all be completely wrong, but some of it should make sense.
