    I just bought some SR front struts and in the future I was considering these rear shocks, would it be a good idea to have the SR struts and these Koni shocks? Or should I just stick to the same brand in all 4 corners

    • Hello, AlexanderT5U1579638 for the best results and ride quality it would be recommended to run a matching set.

    2012 GT with leaking rear shocks. Is it okay to just replace rear shocks while keeping everything else stock?

    • Yes, you can install these Koni shocks while keeping everything else factory. We would recommend the KONI STR.T Front Struts, item 100679 for a complete installation, however, they are not required. http://www.americanmuscle.com/koni-front-strut-1114.html

    I have SR Lowering Springs already, so, if I bought these shocks with the front Koni struts, will I need to buy any other parts to to install them? Or will I be able to install them with just these parts?

    • The KONI STR.T Rear Shock and the KONI Front Struts will install without any additional components, and it will be a direct fit with those springs.

      Great deal!! Great performance part!!!

      I bought this for my ‘90 Mustang convertible and the ride has been nothing but excellent compared to OEM stock that I replaced. I look forward to replacing the front ones sometime soon.

      Perfect all around shock

      If you don't want or need a shock that is adjustable (track use) but still want to eliminate body roll, this is a fantastic option. Ride quality improves (when paired with SR or Steeda springs) as well!

      Wish I would have bought something else

      These do not come with upper bushing and hardware. The shock is twice the size as one at autozone so they don't sell or any other auto parts store. The parts you need are dealership only, with only certain dealerships keeping in stock. The trouble of having to find bushings alone makes these not worth the money. Had them on 3 weeks and already getting bad squeaking sound. Waste of time and money.

      These will be like driving a water bed

      Hello, Here are my thoughts - Pulled them out of the box - one of the Koni's was probably 50 faster to rebound than the other. Thought well - one got more gas than the other but it's really the dampening that does it. Pulled my Stock 2010 GT Motorcraft 100,000 miles of hard highway driving with as much take the curvy back roads as fast as I can to and from work and pulled the rubber off that Koni was too cheap to put in their box. Guess what - at 100,000 miles the Stock GT Motorcraft shocks damp a full 50 harder and return to top a good 100 slower (what's that mean? The Stock shocks with 100,000 miles would outperform these Koni's hands down and the Stock shocks are what I'm supposed to be replacing. These are junk. Put them on your car only if they are the last shock on the planet and you can't find anything else from any other car that you could alter to stuff under the trunk. Oh - the Koni's are about 1 full inch longer than my stock 2010 GT shocks - when compressed the Koni's are a good inch and a quarter longer. You do the math on how much less stroke these things have in them. I guess the good news is the bump stops on the rear axles would never see use because the shocks would be slamming dead bang when you hit that pot hole. No joke - the junk you have on your car even with 100,000 miles will run circles around these supposedly exceeds OEM standards garbage that doesn't approach OEM standards of a shock that's had 100,000 miles of hard use. By the way - the reason it takes a full weekend to install these is - you have to return them and order something that is actually worth putting under your car.

      Great Product

      I was riding on factory shocks that had over 185,000 on them so I figured it was well over due to replace them. These Koni shocks were a great replacement. Noticeable difference right away. The ride is still hard but the impact that you feel is much softer. Took me only 30 minutes to replace. Fit and finish was right on point.

      Good shocks

      I was getting a noise out of the rear when I would go over bumps and thought thought the shocks were the culprit. They were not the problem and turns out rear sway bar bushings were bad. Installed these and they made the ride a bit more comfortable but didn’t notice much of a difference prob because my shocks were still good. maybe I’ll notiice their worth with other suspension mods. Took me about 2 hours to change in a garage with minimal mechanical knowledge, I know others could get it done sooner.

      Rides like stock, handles like a champ

      These Koni STRTs goes hand in hand with my Ford racing K springs. I was worried that after lowering the car it would ride rough but I was wrong. These two combo feels exactly like the Track pack suspension but the car looks and handles much better.

      Where we’re the Bushings?

      So this project is fairly simple using an impact driver or drill. I was under the impression the shocks came with metal and rubber bushings from The install videos on here an YouTube. The bushings on the stock shocks works just fine too lol. Car’s rear feels 100 times better so I would say this is a great buy/ mod.

      Exceeded my Expectations!

      These shocks have been on my car now for about 2 weeks and I absolutely love them. The ride is extremely similar to the stock shocks, but I am sure that I will notice a small change when I put on the matching struts. You really cant beat the price and I would not waste time and money taking it somewhere to get installed because this took me 25 minutes to do both sides and I am not a mechanic. I wish it had come with a new set of bushings and hardware, but that isn't a huge deal because the stock bushings had about 50 life left.

      if I had to describe the difference between these and OEM, id say its a good one step up, don't look to these if your looking to stiffen your ride.

      Nice Shocks

      Make sure you check the condition of the rubber grommets that are reused on the top of the shock tube. I have to order them in. They seem to be a Ford exclusive piece.
