Description
Improves Handling. Installing a set of progressive rate Ford Racing K-Springs will lower your Mustang's center of gravity, which will reduce squat during acceleration, body roll in the corners, and excessive nose-dive under hard braking. Ford Racing K-Springs are great for daily driving, street, and even occasional track use.

Aggressive Stance. The Ford Racing K-Springs not only improve the handling of your S197 Mustang, but they also improve the overall appearance by lowering the ride height approximately 1.5" to eliminate that nasty raised 4x4 truck look for a more aggressive muscle car stance.

Clears Stock and Aftermarket Wheels & Tires. These lowering springs were engineered to be compatible with your stock factory size wheels and tires, as well as AmericanMuscle’s pre-configured wheel and tire combo kits (specific to your generation), to assure proper clearance with no rubbing issues.

Application. This set of four Ford Racing K-Springs are designed specifically for use on the 2005 to 2010 GT Mustangs Coupes. They will also fit 2011 and newer GT Coupes when used in combination with Ford Racing M-18183-C upper strut mounts and M-18000-A dampers (sold separately). Does not fit V6 or convertible models.

Ford stock vs Ford K spring

The Ford K springs are worth the money. The ride is much firmer the car looks better and the awful body roll when cornering has been substantially reduced. Beware that lowering the car 1-1/2" makes curbs,

    !!! Important info for use on 2011 GT's

    The following info is from personal experience of a guy with more than 35 years of wrenching experience. If you want to use the "K" springs on the 2011 GT, read the FRPP catalog carefully. The M-18000-A struts/dampers and the FRPP M-18183-C strut mounts are a package deal - not a menu deal. The 2011 strut "perch" is different, and the mounts are taller, so the 2005-2010 struts do not seat properly on the stock mounts. Oh, you will read on the 'Net that they work fine, and Ford is not clear on this point, but after we did all the work, we found that using the "K" springs with the stock mounts allowed too much play, and did not bode well for long-term stability/safety/wear. After numerous calls to FRPP, here is the right setup for the 2011 GT: 1) 5300-K springs 2) M-18183-C strunt mounts 3) M-18000-A struts/dampers Once you get all these installed correctly, the end result is very sweet: greatly reduced sway, crisp turn-in, greatly reduced nose-dive under braking, and sharper handling all around. The car also looks great with the 1.5" drop! Looks both smaller and meaner, as a sports car should look. Ride is a bit choppier, especially if you decide to ignore these recs and stay with the stock dampers - they are not setup for the taller 2011 strut mounts. FRPP should be clear in their catalog that the 3 parts are required; when I read the first 2011 catalog and spoke to someone at FRPP, it seemed that the dampers were considered a enhancement; no, they are required to make the whole package work right and be safe. Thanks to Steve Horn at Ford Racing Perf Parts for helping me sort this out - I had to eat the double labor time though. Hope this helps.

    Ford stock vs Ford K spring

    The Ford K springs are worth the money. The ride is much firmer the car looks better and the awful body roll when cornering has been substantially reduced. Beware that lowering the car 1-1/2" makes curbs, humps and holes more hazardous to the low points under the car. I have a couple of scrapes after 2 weeks. Fitting the springs yourself is straight forward and the online instructions are very accurate. Depending on the equipment you have and the skill level it could take longer than the instructions indicated. I would allow at least 3 hours. Getting the old parts off takes more time than putting the new parts on. Compressing and decompressing the stock springs was time consuming with the $10 spring compressors from Harbor Freight Tools. I think that the addition of stiffer shock absorbers would also improve the cars handling and see them as a future purchase. One final point the ride is harder so if you like a softer ride and take corners like an old lady these are not for you.

    Soooo Easy

    These springs are great! They dropped the car just perfect. Not so low that you have to worry about scraping your undercarriage on everything. The ride is a little bit stiffer but the handling gain is well worth it. Install was sooo freakin easy! It took about 1 1/2 hours with 3 of us taking our time. You wont regret going with these springs. They will clear 285/40/18's no problem, they leave just enough room that you could go with a little bit taller tire. I hope this helps!

    2009 Bullitt with Ford Racing Lowering Springs

    I love these springs! I chose to go with the Ford Racing Springs over all the others because numerous shops told me they ride the best out of all the lowering springs out there and will give it a very aggresive stance. I also chose to go with the Ford Racing Springs because the Bullitt has some Ford Racing parts on it from the factory. It is a must have, aggresive stance good ride, and good price. What more can you ask for?

    Lookin' Good

    Quit contemplating, buy them already! Straight forward install on my 2011 GT/CS, which came stock 19" wheels. Installed by myself in a few hours, having really no idea what I was doing, just following a popular how-to on line. If you have a decent set of tools and mechanical inclination, you'll have no problem. I'd say air tools are a must for removing the strut nuts. No spring compressor needed with the front of the car raised. Love the improved look and less body roll. I am currently using all stock parts (struts, strut mounts, pan hard bar) with zero issues. No clicks, no clunking or wierdness. My local alignment shop only charged me an inspection fee, because everything was still well within spec! Definitely stoked!

    Ford K Springs

    These are a great deal. Easy install. Ride quality is a little firmer/bouncy with the stock struts (some Tokicos wil fix that). Drop height is just right. I have a CDC Classic chin spoiler. I was worried that the spioler would have clearance issues, but all is well. The spioler was dropped by 1/2 in. These springs really give the Stang some attitude!

    Ford Racing K Springs

    This set of springs does exactly what it says they do. The ride was became a little rougher, but the handeling you get out of them is great. I would recommend a front end alignment. This was a great project to do myself, with basic hand tools. Also I did have to rent a spring compressor from the local auto parts store. All in all it was not hard to do.
