    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.

        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

        I recently was in a car accident (not my car was a passenger) when I lift my foot I cant get it to get driving because it stalls. I'm thinking if it takes less force itll help.

        What is the diameter of the wire? I purchased my car used with quite a few basic mods and I am trying to figure out if this has been done.

        So, does the the lighter Steeds spring make the clutch easier to depress? I often put it in neutral when stopped at a long light because the factory clutch is pretty stiff and my left leg gets tired from holding the clutch down for several minutes at a time.

        • Yes this clutch spring will help with the clutch feel when it is depressed

            Must Have!

            I read some negative reviews before buying this, but at the price it was hard not to try since I was not a fan of the stock spring, especially when using an RXT clutch. I have to say I really like the peddle feel and that the clutch peddle doesn't want to shoot up like a rocket. Install is super easy and I would ignore the vice grips, etc. for compressing the old spring. The perch/spring assembly pulls out easily by hand. Takes 30 seconds to install.

            Clutch upgrade

            The stock spring lets the clutch pedal come out nice until the clutch is ready to bite, then it launches the pedal out. Stalls engine when your not ready for it. This Steeda spring makes the pedal smooth top to bottom. Easy install too.

            My thoughts on the Steeda 35lb spring

            I checked a lot of reviews prior to buying the Steeda 35lb/in clutch assist spring but finally went ahead and did it. To me, it makes the clutch feel way better. It wont feel like a totally different clutch but I can surely tell the difference and I like it!! It is worth every penny. Since I had watched a video on it first, it literally took about 5 minutes to install.

            This part made my clutch so much easier to press down then the OE from Ford I feel like I have so much more control of my car I highly recommend it!!!

            17 mustang gt premium

            I can finally feel the clutch engagement. Spring is super easy to change in under a minute, simply push the clutch pedal in and take a screwdriver and slide the spring off the bottom rod, replace stock spring with steedas. Literally took about 30 seconds

            Good bang for the buck

            I installed this clutch spring about a month ago and I have to say it was worth it. the 185 lb spring the car comes with is very heavy and clunky. Installing the 35 lb spring tightened up the feel of the clutch and now I find no problems when shifting. The only downside is the plastic perch mounts which I want to replace, this is not a problem with the spring but if you want to buy this I recommend buying the full kit.

            I hated my manual mustang til I bought this

            I only had it a week and just couldn't get a good feel for my mustangs insanely plush pedal. This rectified that, took me a couple minutes and a little painful getting under the dash to do it. But so worth it! This paired with the hybrid 3 shifter from barton made me love my car. I liked it, now I love it.
