Steeda's ever so popular S197 Clutch Spring Assist is now available with a Heavy Duty Spring Perch assembly, therefore eliminating the worry of you breaking the factory one upon installation or removal.

Your 2011-2014 Mustang comes with a 200 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 S197 Mustang.

Many Mustang GT, V6 or Boss 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 S197 Mustang Clutch Assist Spring 95 lb/in into your GT, V6 or Boss.

Our Steeda S197 Mustang Clutch Assist Spring 95 lb/in completely replaces the factory 200 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.

Product Benefits:

  • Improve clutch pedal engagement feel Modulate your clutch engagement with ease
  • Piano wire construction with high tensile strength and high elastic qualities Consistent spring rate and minimal sag even after repeated use
  • More linear clutch feel Complete replacement of factory 200 lb/in clutch assist spring
  • Avoid slave cylinder damage due to removal of stock clutch spring Steeda quality, backed by a lifetime warranty

Decent product, recommended
Overall, the spring doesn't change the feel very much which was surprising. But, it has a very noticeable change right where you want it. The point where the spring transitions between compression and extension is much smoother and less dramatic making buying the spring an easy choice. The spring alone gets 5 stars. The perch is debatable. It's a good product, but I don't think there are any functional advantages over stock. I purchased it because I couldn't afford the downtime waiting for a new one if the OE perch broke. It provided some nice peace of mind making it worth the price for me.

The clutch pedal on our 2012 Mustang was distinctly non linear on release, making it hard to modulate launching the car at the dragstrip. We replaced the factory parts with Steeda's spring and perch. This made it much easier to control clutch application and launch the car more consistently. Glad we bought this part.

Great Upgrade, Perfect Timing!!!!
My wife has had problems with the stock plastic perch on her 2014 Gt almost since it was new. I had it out several times deburring it greasing it but sometimes the pedal just did not return properly. I replaced the spring with the Steeda spring a year ago which helped a lot. The perch still seemed to be part of the problem, I tried to buy a perch from Ford but Ford will only sell you the whole pedal assembly! Well last week in 9 deg temps my wife went to start her car and when she pushed down on the pedal SNAP the perch broke and locked the pedal down. I called Steeda to see if they had finished building their perch kit for her car and it was just coming out of production so they did me a great service in sending one over night! (thanks you were a life saver). Took all of 5 min. to install and what a difference!!! My says the clutch has never worked as well as it does now. (and you know never to argue with your wife.) I can not say enough good things about this company and the people that work there, if it wasn't for their upgrades my mustangs would not be half as much fun to drive as they are. Thanks again guys, Scott Larson
