Just bought a set of Koni yellows since they went on sale. Is there a trick to the rears?

One will not extend at all once compressed...seems odd but ive never had adjustable shocks/struts before.

 

They have to be under a load. Once you install them they will be OK

 

Perfect. Wanted to make sure before installing them.

 

My fronts did the same thing before I installed them and I was concerned they were defective.
Have them on the car for over two years and they still work great!

 

You will love them!
Great shocks make a real difference!

 

I just got mine Friday. Did you notice the difference in how long it takes them to come back when you dial in stiffness? Insane.

 

I have had a set of the Koni Yellows on 2006 GT for a year and half and they do change the car for the good. I am on full soft and the ride is stiff. Full tight and the suspension hardly moves and is brutal. Combined with a set of Michelin Pilot AS3s, and the handling is best I have ever owned of all my Mustangs. I also have a 1988 GT with Koni Reds at all six positions and the results are similar with improved handling.
