Description


Steeda's ever so popular S550 Clutch spring assist is now available with a Heavy Duty Spring Perch assembly. Therefore eliminating the chances of you breaking the factory one upon installation or removal.

Your 2015+ Mustang GT 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. The clutch pedal travels in a circular arc, with the spring assist in the middle of that clutch pedal travel. The middle of that motion compresses the spring initially and then allows it to extend after the first 30 degrees of travel. The combination of a high-rate assist spring and motion of the pedal during engagement causes a non-linear and sometimes confusing pedal feel. Having a non-linear pedal feel makes it hard to modulate the clutch on your Mustang GT, EcoBoost or V6.

Many new Mustang owners have found that taking out the stock OE spring will give you somewhat similar results, but realistically the clutch becomes far too heavy especially if your Mustang is daily driven. Most owners fail to realize the prolonged effects of simply taking out your factory OE spring and not replacing it with another spring. By negating your factory clutch assist spring you will notice chatter/NVH from your clutch pedal. Your clutch pedal will never fully return to stock position without any assist spring, and over time your slave cylinder may begin leaking due to constant pressure on its seals from the clutch pedal not returning to the stock position. Avoid these problems in the future by installing our Steeda S550 Mustang Clutch Assist Spring 35 lb/in into your GT, EcoBoost or V6.

Our Steeda S550 Mustang Clutch Assist Spring 35 lb/in completely replaces the factory 185 lb/in assist spring. Our engineers have honed in on just the right amount of spring rate to get you the perfect clutch pedal feel you look for in a Mustang. This assist spring is manufactured from piano wire that naturally has high tensile strength and high elastic qualities. Our piano wire spring ensures a consistent spring rate and minimal sag even after repeated use. With the addition of our clutch assist spring, you will notice a much more linear feeling clutch - the reason being is that we take out much of the influence involved in your clutch pedal motion caused by the assist spring, allowing you to feel exactly what is happening with your clutch engagement.

You asked for it and Steeda delivered... After multiple requests for a heavy duty aftermarket solution for broken factory spring perches Steeda went to work and designed a piece much stronger. So much so we guarantee it for life! Fits perfectly with the OEM spring or the Steeda clutch spring. Fits all models and will help convert your 2015-2018 GT350 over to the Steeda clutch spring which gives you a much better feel of your clutch.

Note: Will not fit the 2019-2020 GT350. Clutch spring may be incompatible with Ford Performance M-9452-M8 no-lift shift strategy.

Hi everybody Brian from Steeda.com, here today spotlighting our Clutch Spring assist for the S550 Mustang. Most modern Fords equipped with a manual transmission including your Mustang have a clutch spring assist. The idea behind this is, for the spring to actually aid in pushing the clutch pedal down but with the use of a hydraulic clutch system this kind of seems repetitive. Now the manufacturers had good intentions in that they can use a slightly heavier pressure plate for the increased torque and horsepower these cars have today but the reality is a very vague feeling as you're trying to let the clutch out. You don't feel the engagement point. We have a solution! Let's start with the spring itself. We've developed this to be a much lighter rate, 35 pounds to be exact and want it to be the specific length needed for the rate that we've gone with. This means that when the clutch pedals all the way out, the spring can sit flat, yet it's plenty long when you push the pedal all the way to the floor. Now the spring is offered by itself. We do recommend that you be very careful if your car has some miles on it or it's a few years old even if it's brand new when you're disassembling the factory spring perch but rest assured we do have a spring perch for you if you damage the factory piece. The spring perch itself is also an upgrade to the factory unit. We've constructed a durable Delrin and it can be used with the factory system spring or even better our assistant spring. We do recommend greasing the male end of this, for smooth operation. Now the way to really do it though, is just to buy the kit. This way you can keep the factory assembly altogether, install our kit and enjoy it and when I say enjoy this let's face it, every time you're going through the gears, every time you're shifting, you’re pressing in the clutch and you're letting the clutch out and this is one of those little things that you can do to your car that makes a huge difference in how you enjoy driving it.

Clutch Helper Spring
Wow! Night and day difference. This is how the car should be from factory. The clutch engagement point is more pronounced and more crisp. Highly suggest!

Easy mod/upgrade
Not that I had a problem with the factory clutch spring, but decided this was an easy mod/upgrade to try. That said, I made the change and agree with other reviewers. The change in pedal pressure and feel is noticeable, and it definitely improves smoothness and engagement. Two install notes: 1. Expect some spring backlash when removing the stock assembly. You can't quite release all the spring tension or compress the stock spring fully, so take precautions. 2. Expect the stock perch to break, snap, or crumble. Order the Steeda spring and perch kit - you'll be happy you did.

Clutch spring and perch kit.
Simple installation resulting in superior clutch "feel". Factory spring left driver "hunting" for engagement point. Excellent first mod for my 2020 Bullitt!

Owner
I ordered the spring and installed myself. Helpful to have the right pliers to compress the factory spring. Make sure to use white lithium grease on the new spring mount and perch kit. I installed by hand, all in less than 5 minutes. Now I can absolutely feel the clutch engagement making more crisp and precise shifts possible. Best mod. for the least amount of money in my opinion.

Best Mod - pls don’t think twice
Easy to install! Long nose locking pliers would do the trick. Steeda perch upgrade kit is so much better than stock and you would be very happy with what this kit had done to your shifting!

Thank you Steeda! I can feel the engage/disengage point of my clutch now. That makes shifting smoothly much more easy.

Lord and Master
Makes the clutch feel normal by replacing the overassisted stock spring. Mod a pair of cheap needle nose vise pliers like the Humble Pie review showed. I also used one of my bar clamps in spreader mode to hold the clutch pedal down. With those two items I could change this out in five minutes.

The Kit is the trick!!
Please don't cheap out and try to put the Steeda Spring on the OEM Ford guide - the Steeda Delrin guide is 100% better than the plastic one from the factory, which broke off in my hand... And, IMO, my clutch control is a whole lot better with the Steeda kit - I can really feel the clutch engage now. I definitely don't regret buying the kit!

Best upgrade under $100
Seriously , world of difference!! If you say you can't notice a difference after installing this , you are insane. Less than 5 minute install. No need for any special tools , vice grip for removal and installing the new one , you can do by hand. Then get in and feel the difference immediately!! Steeda nailed it !! Next up for my Stang ... Steeda springs and sway bars

Humble pie
Long story short, got the car. Read the post regarding the spring. Figured is was a non issue, solved with some seat time, did not.Very good upgrade does what is advertised. For anyone doing the swap. Cut reliefs in the jaws of some throw away HF needle nosed Chanel locks..Helps a great deal..... take my word for it.

Clutch Assist Spring
Makes pedal noticeably heavier but not tiring. Shifts are much smoother since you can feel the clutch engaging.

Easy to install
There is no mistaking the quality of the Steeda products. When compared beside the factory part, you will notice how well built the assembled perch and assist spring is. If unsure how to install, YouTube has your back. Took 15 minutes now the pedal feels like it should.

Must Have!
Hated how heavy the stock clutch felt and a friend of mine recommended this for my 2019 Bullitt and it's a night and day difference. You can actually feel the clutch and shift better and faster. 100% recommended..

2018 Shelby GT350 - shifting is now smoother thanks to this spring assembly
Having driven a number of performance cars w/ manual transmission, I was quite disappointed with the clutch in my new GT350. I was pleased to read on the forums about this low-cost solution. My biggest regret is not doing this spring upgrade sooner. Thanks to Steeda for this solution. Driving enjoyment has increased tremendously due to the much smoother clutch and shifting.

Wow, you have to replace yours
WOW, yes really... WOW !! I wasn't convinced all the hype would stand up but boy was I wrong. I kept thinking, the factory clutch doesn't feel that bad, surely this spring/mount assy can't be that great. Well it is, really transformed the pedal feel, this is how it should've come from the factory. Linear resistance throughout the arc, amazing change. Thanks for the cool products guys!

What a difference
I had recently purchased a 2015 GT and was beginning to think that I had forgotten how to drive a manual. If you are having issues with lurching in the lower gears and are beginning to think that you have forgotten how to drive a manual...This is your fix. This inexpensive mod cleared up those issues. It literally took 10 minutes to install and has made a world of difference. I must agree with the other reviews, referring to the spring, it is a MUST!

Excellent
Steeda makes some of the most quality parts hands down and this is no different. Nice lighter clutch feel where you get a honest sense of the clutch engagement. The oem part is absolute junk, this is a must have.

Best Mod I've Done
Honestly this is how the car should have come from Ford. Taking out the stock 185lb/in spring was the first thing I did within the first week of owning my car. I hated the stock spring and was happy without one. Only problem was that my clutch pedal wouldn't come back up all the way. I decided to spend the money on the Steeda 35lb/in spring and perch kit (Since the stock plastic one broke on me). It was so easy to install, probably took me 10-15 seconds. Getting out the stock spring was so much harder. I honestly thought I was happy not having a spring at all..... until I drove with this mod. The Steeda spring made a world of a difference. The clutch engagement is much smoother and linear. It doesn't get rough/bucky towards the top like it used to. My mustang feels so nice to drive and now very similar to all the other manual cars I have owned. I couldn't be any happier. Plus the clutch comes back up all the way and doesn't have issues in the cold weather with engagement. Long Story Short..... BEST MOD I HAVE DONE SO FAR TO MY MUSTANG AND I RECOMMEND IT TO EVERYONE!!!!!!
