    Features & Details

    • Improved Clutch Pedal Feel
    • Heavy-Duty Piano Wire Construction
    • 35 lb./in. Clutch Assist Spring
    • Replaces OEM Spring for Easy Installation
    • Limited-Lifetime Warranty
    • Fits 2015-2019 Ford Mustang GT, EcoBoost, and V6 Models
    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.

    5 Top Rated Questions

    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.

      I was tired of guessing where the clutch engaged, had this eneven feel when pressing clutch in and out. This fixed that feeling to a more solid feel in the pedal. Highly recommended this a first upgrade to your stang!!! 5 min changeout ,,,

      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!

      Works as advertised

      Was on the fence about this product for a while. Now i wish i would have gotten it sooner. All of the clutch weirdness is gone. Now i want to drive the car more. Installation could not be easier. It went on in like 5 minutes. All you need is a long flat head screwdriver that is it. Push down the clutch pedal with your left hand and work the stock spring over to the right with the tool slowly and thats it. Installation is the reverse of removal. This should be your first mod as soon as you buy your s550!

      Feels like my old '96 Cobra now

      I do not drive my mustang as an everyday driver, that being said I wanted a stiffer clutch with more resistance like my '96 Cobra had, this inexpensive and quick mod makes my S550 clutch feel like that way, which is so much better and enhances your feel when engaging the clutch. Recommend absolutely

      smoother than stock

      can really tell the difference between the stock spring and this one once you get them next to each other. you can compress this is one hand, while the stock is hard using both hands. the clutch travel feels more consistent now.

      WAS SKEPTICAL ABOUT THIS SIMPLE SPRING, BUT AFTER DRIVING WITH IT FOR A FEW WEEKS I HAVE TO ADMIT IT IS WELL WIRTH THE MONEY. RECOMMEND TRYING WITH SYNCRO SHIFT II FLUID TO IMPROVE TRANSMISSION FEEL

      Steeda clutch spring assist

      I recommend this anyone out there that still has the stock clutch spring assist. It gave the clutch pedal a more realistic feel and made the shifts a whole lot more smoother. It is well worth the money and it only took less than 5 min to install.

      First mod for sure, not up for discussion

      Could not stand the clutch feel on the 17 GT and did some searching and found this, installed it and now the clutch feel is night and day compared with the stock spring. I can actually feel the clutch engage now and the shifts are so much smoother as a result! Worth the $20, its a no brainer!!!

      A must have

      This small part makes such a huge difference to the way it drives. The clutch disengagement was very inconsistent with the factory spring. Now it’s not only consistent but feels smoother and more linear. Buy it, it’s cheap and easy to install.

      Hard to get used to

      Before writing the review I admit there could be other factors, such as a weak pressure plate. The clutch pedal feel is very weak. I am not able to tell when the clutch comes back.
