Steeda's new Pro Active line of shocks and struts feature patented frequency selective damping technology to address needs specific to the S550 Mustang IRS chassis. This new line was developed to offer superior ride and control experienced under the most brutal driving conditions. Unlike previous performance versions that offer firmer dampening, these units provide more control on rough surfaces by maintaining constant tire contact with the road surface. Combined with a set of Steeda lowering springs, the combo is the ultimate highway driving experience with amazing comfort and stable control. During hard launches, the rebound setting of the Active dampers limits front end rise resulting in quicker 0-60 times. During panic stops and hard braking, the compression characteristics limit front end dive. On corrugated surfaces where the OE originals allow the car to porpoise, these units maintain a consistent level ride. Co-developed with an OE manufacturer to Steeda specs, these dampers will provide life long predictable handling and consistent ride quality. Their durable coating will not corrode due to road salt or chip due to gravel and road debris. We tested these units under real world conditions on the gnarliest highways and bumpiest back roads of rural America. We are confident they are the absolute best performing option for your daily driven pony car.

Features and Benefits:
  • Proprietary Active valving ideal for safest control on rough surfaces
  • Superior ride on all surfaces
  • OE quality construction
  • Steeda engineered and battle tested

Customer Testimonial:

Just wanted to let you know that I had my track day last weekend with all the new components. The car performed brilliantly. Not one problem, it felt incredibly well balanced, and the highway ride there and back was great too. Definitely an improvement over the OEM parts, with just a better feel. My best time was two-tenths of a second faster than the guy with the GT350 that was there! I really love the new suspension, thanks for the recommendations.

Great suspension!
Reached out to [email protected] with a couple of questions. He advised me to use the the struts with the Steeda minimum springs. Great combination! The car feels amazing and the stance is great!

Improved Ride Quality
These are a great replacement over the factory shocks and struts. I put these on my 16 GT and I definitely feel the difference. For daily driving these are amazing. Bumps in the road basically no longer exist. I occasionally go to the track and do the road course and these hold up very well. I also got the billet rear shock mounts and it’s definitely worth it. These also improved the ugly wheel gap. My car’s stance is way more appealing. I had an issue with installation and turned out it was one of the parts. I took it to Steeda in Pompano since I’m local told them the issue and they replaced it without a problem. I love Steeda products but their customer service keeps me coming back.

Great Product
Living in Birmingham where the road are tough, daily driving a Mustang was a challenge. The roads, as well as some spirited driving, ended up busting one of my shocks and struts so I decided to slap these on my car and wow what a difference. The overall ride quality is so much smoother now over bumpy roads but still handles well in high speed turns and cornering. They truly are the best of both worlds. There were certain roads I would avoid entirely due to their conditions but now I can reasonably "float" over them compared to my stock shocks and struts.

Love these Pro-Actives!
I have a 2015 GT with factory Performance Pack. I was pretty happy with the stock suspension, but in some situations it was a little harsh, like highway expansion joints, big dips in the road, etc. On the track it was great, but real world I wanted a little more refinement. Steeda recommended these Pro-Actives to meet my needs. I was adamant that I did not want to lose any performance over stock, just wanted a little more comfort. They definitely delivered. I paired them with the Steeda minimum drop springs, and what I have now is exactly what I wanted. On the road, the car doesn't clunk over expansion joints, it doesn't porpoise over dips, my wife does not get her head bounced back into the seat over bumps, etc. It isn't really comfortable , its still a firm sport suspension, but just not as rough. But on the track, it really comes alive. Its like Performance Pack Plus. In a day on the track, not once did I feel like the suspension was holding me back or causing me any problems. The car felt tighter and more planted, rougher pavement and corner curbing did not upset it at all. It's almost a European feel. Another plus is no messing around with adjustments, its just always ready to handle what I throw at it. The minimum drop springs look awesome too, again, like stock plus, gives the car the stance it should have had from factory without looking lowered. If you are on the fence for shocks and struts, go with these, you will not be disappointed!
