    More Precise Clutch Pedal Feel and Control. The Steeda 35 lb./in. Clutch Assist Spring replaces the 185 lb./in. spring that comes in your Mustang. The high rate of the OEM spring leads to vague clutch pedal feel. Converting to the Steeda 35 lb./in. Spring helps your clutch pedal feel more linear and direct. This simple modification can transform the way your Mustang feels.

    Less Clutch Chatter. Replacing your stock clutch spring with the Steeda 35 lb./in. helps your clutch pedal return completely to the at rest position. This both reduces clutch chatter and prevents slave cylinder wear. A pedal that does not return to the at rest position can affect clutch engagement/disengagement. It can also damage the slave cylinder due to constant pressure being applied to the seals.

    Piano Wire Constructed. Heavy-duty piano wire provides the Steeda 35 lb./in. Clutch Assist Spring with high tensile strength and high elastic qualities. The design also provides a consistent spring rate and prevents sag over time.

    Warranty Information. Steeda backs its 35 lb./in. Clutch Assist Spring with a limited-lifetime warranty. Some exclusions or limitations may apply; please see manufacturer's warranty for complete details.

    Application. The Steeda 35 lb./in. Clutch Assist Spring fits 2015-2019 Ford Mustang GT, EcoBoost, and V6 models.

    How does this spring effect clutch feel? Does it make the clutch feel stiffer? Thanks!

    • Your 2015-2017 Mustang comes with a 185 lb/in clutch assist spring installed from the factory. This high-rate spring is what causes such a vague and disconnected clutch pedal feel. Using this Steeda 35 lb./in. Clutch Spring Assist will allow a softer and smoother return.

    I see this spring does not fit the gt350. Is there a spring comparable that will fit?

    • At this time, we are unaware of any version of the Steeda 35 lb./in. Clutch Spring Assist that is designed for GT350 models.

    Do you need to install the perch upgrade aswell?

    • The Steeda 35 lb./in. Clutch Spring Assist does not require the spring perch upgrade, however we do recommend it to ensure longevity.

    How does this compare to omitting a spring entirely? I have been driving around for the last 2 years without any assist spring and have also upgraded to a twin disk. The clutch pedal currently feels very springy and doesn't always travel back to the top/original position (though, when it doesn't it gets very close). Would installing this spring make much of a difference to not having one at all? The clutch feel in the S550 has never been great, but how much of it has to do with this spring?

    • The clutch spring in the S550 is a big part of the clutch feel, in addition to the hydraulic clutch actuation system. The Steeda 35 lb./in. Clutch Spring Assist will help in making sure you get a full return to the top, while still maintaining an improved clutch feel over stock. We recommend pairing this with the Steeda Clutch Spring Assist Perch Upgrade Kit and a Steeda Heavy Duty Braided Hydraulic Clutch Line to achieve the best pedal feel possible. Both of these are linked below: https://www.americanmuscle.com/steeda-clutch-spring-assist-perch-upgrade-kit-15117.html https://www.americanmuscle.com/steeda-hydraulic-clutchline-2015.html

    Do you have to purchase the assist perch upgrade kit with this spring?

    • The Steeda 35 lb./in. Clutch Spring Assist does not require the perch upgrade, however for optimum pedal feel we do recommend installing the Steeda Clutch Spring Assist Perch Upgrade Kit.

      Improved Pedal Response

      Replacing the factory spring with this lower rate spring greatly improved the pedal feel when engaging the clutch. It allows you to have a better idea where the clutch engagement point is. Hill starts are easier as the pedal does not feel like it wants to push your foot while clutching out, allowing you to have more control. I noticed a big improvement in the smoothness of my 1-2 shift both while driving around town and getting higher in the RPMs. The pedal does have a heavier feel though, however it only requires ~10-15 more effort to depress. Overall this is a great product that helps connect you more with the vehicle, it also installs quickly.

      Huge difference

      This spring honestly is one of my favorite mods because it allows you to be more comfortable and connected to the clutch. Making it easier to use and more reliable for when your banging through gears. I would recommend to anyone with a manual mustang.

      Great feel

      This definitely makes it much easier and predictable to drive with this. Easy to install, i didnt need needle pliers either. Just rotate the spring so you can get a grip with regular pliers and you should be able to get it out.

      Works as advertised

      Getting the old spring out is the toughest part. And that’s not bad. Be sure to put down a towel as the perches have a little lithium grease on them and if you drop the assembly it might get on your carpet. I just pushed the clutch in and walked the spring off the bottom perch with a screwdriver. Then put the new spring on the bottom perch first. Smoother operation of the clutch with this spring.

      Steeda spring

      This spring definitely has more spring back and has consistent feeling every press over stock. Took some getting used to but I love it now! Took less than 5 min install, don't even need needle nose pliers just pop it out from the bottom while pressing the pedal in

      Easily the best $20 I've spent

      The Steeda clutch spring is worth every penny. The clutch pedal feels 100 times better. Being that I sometimes drive this car in heavy traffic, my leg doesn't get tired from having to constantly push the clutch pedal in. The install took all of 10min. to do. Easily the best thing you can do for your manual transmission mustang.

      Nice product

      My stock spring was already gone so I wanted to make sure i didn't create a problem with it gone. This was an easy install and now the pedal has the same feel all the way up. For the money a good insurance policy :)

      Clutch spring

      This spring is a hundred time better than the manufacture one.I would highly recommend buying the whole assembly,because you can easily damage the top housing.

      What a transformation

      I can’t believe for $20 I feel like I have a new smooth clutch. The stock clutch spring had no feel and made for jerky shifts. Now it’s smooth as silk. Any S550 owner with the MT82 should make this their first mod!
