    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.

            Clutch spring

            Clutch spring definitely assists with the shifts. You can actually tell now the grabbing point vs without it it was very sloppy.

            LOVE IT

            It makes the clutch feel like it should. Honestly. A #1 MUST BUY if you like lighter clutches, because the assist spring from the factory is truly terrible. I felt like I had to re-learn how to drive a stick until I got this spring.

            I can drive a manual again

            When I first purchased my car it felt like I was just learning to drive a manual. The next day I purchased the Steeda spring and by the weekend I had it in my hands. Install took maybe 45 seconds, and my driving experience changed for the better. No more lurking and jerking. This spring did wonders for me.

            Just go for it!

            For the price, this is honestly a no-brainer. Makes going from a stop much smoother and helps the 1-2 shift. Takes like 3 seconds to install as well.

            Works great.

            Going from the stock 180lb./inch spring to this 35lb. spring really makes a big difference. I was having trouble with the one letting the clutch out too quick, a grabby feel. This has fixed that issue for me. Love it. Install with a good rugged pair of needle nose Vise grips is 10 min Max.

            To early to tell

            I just put it in and drove it. Unfortunately I damaged the old spring getting it out. Difference being a 6-2 guy and your gal doing it with the space available but your video was accurate. The initial feel is heavier than the old one when i start out in Rev/ first gear but as I go thru the gears it seems better than the original in terms of feel and engagement. I am still not quite use to it. The quality of the plastic part on the top fitting was good but not as good as the bottom.

            This is hands down the best mod I have put on my car, I can't believe how much of a difference this thing makes for 20 bucks 21/5 would by a second one for no reason.

            The clutch feel is amazing. Before it seemed to spring back too quickly and felt as heavy as a brick. Now its smooth and easy

            Nice even feel

            Luv this upgrade. The factory spring is garbage. This promotes a nice even feel when depressing the clutch pedal with less resistance.

            Good cheap upgrade

            Didn't like it over stock at first b/c it gave the clutch a heavier feel and I almost went back to the stock spring the same day. After giving it a couple days I was happy with the feel of the Streeda spring. Don't expect a day and night difference but the Steeda spring better overall, you can feel the engagement point.

            Improved clutch feel

            I bought the 35lb spring and perch. Took 5 minutes to install with just a needle nose plier to remove the stock parts. The feel is tighter when I press and smoother when I depress. There is a perfect amount of slop before the clutch engages when pressing down. By slop I don’t mean it is loose or jiggles. I mean that the tension is almost unnoticeable. The slop makes the clutch travel feel shorter. When depressing, the lighter tension makes it possible to anticipate the clutch catching the next gear. The stock spring had so much tension it wanted to snap back so strong that it made it feel vague. So, I’m happy with it and it was worth the $100 imo.
