Mine just went in whatever way they came out of the Box. No problem. No Spring Compressor needed, so long as you unbolt the Shock Absorbers on both sides. Just wish I had changed the Rubber Seat things.
Agreed, the bilstine ones I put on have no dots but have the name printed on the spring, putting them on the same way as the original, the name is upside down and if I remember there is an arrow in also printed on, the arrow is facing down on the ones on my car because when stood up and standing straight that's the way the arrow faces.
