    Shelby GT500 Original Equipment. These Ford Performance Jounce Stops are the same exact ones found as standard original equipment on the 2012-2014 Shelby GT500 Mustang.

    Improves Ride Comfort. These GT500 Jounce Bumper Stops may look like your stock ones, but the difference is that they are much softer/spongier than stock. So when the jounce bumpers compress, they release slower than stock to provide a less violent chassis reaction when the vehicle bounces off them. This improves stability and ride comfort when used in conjunction with FRPP lowering springs.

    Kit Includes. This Ford Performance Jounce Bumper Kit contains two front jounce stop bumpers and two rear jounce stop bumpers.

    Legendary Ford Performance Quality.
    When you're adding suspension parts to your Pony, you can't go wrong by installing parts from the folks that know it best. Ford Performance's legendary quality ensures a perfect fit and years of hassle-free use.

    Application. This set of four Ford Performance Jounce Bumper Stops fits all 2005 to 2014 Mustangs with Ford Performance Lowering Springs installed, including the V6, GT, Bullitt, Boss and Shelby GT500 models.

    Technical Note. These Jounce Bumper Stops are compatible with the following Ford Performance spring kits; M5300K, M5300L, M5300N, M5300P.

        Where are the front ones? I have a 2014 v6 lowered 1.5inches but i cant seem to find the front jounces. Ive looked everywhere but nothing. Anyone know if tue 2014 models have them? If so, where? Thanks in advance!

        • The Ford Performance Jounce Bumper Kit comes with both front and rear jounce bumpers.

        Will the Jounce Stops work on a non-lowered Mustang? I want to know if these would work on a non-lowered 2007 Mustang V6 with stock springs? The description states to use with lowered springs, but will these cause a problem if installed?

        • No, there should be no problem. they're exactly the same as the factory ones with softer materials. if your car is not lowered you wouldn't be able to feel the difference comparing to those who lowered their mustangs.

        Will these work on a 08 Mustang GT convertible lowered approx. 1-1.5"? This is a 4.6 with a supercharger.

        • This kit is designed to work with the Ford Performance springs, as long as you have the Ford lowering springs then this kit will work perfectly for your lowered Mustang.

        I was wondering if these come with installation hardware such as the bracket and the screws? (I am particularly wanting the brackets). I realized that my mustang is missing both the jounce bumpers and the brackets. Where it says "what is in the box" it does not mention the brackets. Let me know. Thank you for your time!

        • This kit includes (2) front jounce stop bumpers and (2) rear jounce stop bumpers.

        Lots of questions regarding different types of springs and whether they work with these bumpers. I’m planning on buying Roush springs, which only lower the car about .5”. Will these jounce bumpers work with only a slightly lowered setup?

        • Ford Performance Jounce Bumper Kit will fit other brand 05-14 lowering springs

        A little confused. One staff member says these will work with SR springs, two others say Ford performance only. Why would these not work with other brands? Looks like they just bolt to the arm and the springs, dampers will not matter. I have eibach pro dampers with Vogtlands springs. 1 answer
        Will these work with the boss 302 T springs? I ask because they appear to be taller than the jounce bumpers supplied with the ford racing boss 302 spring kit. 1 answer
        Does anyone know if these FRPP jounce bumpers will work with Steeda lowering springs? Ideally, anyone know if they work with the Boss 302 Steeda lowering springs? 1 answer
        Will these work with sr performance lower springs or do they have to be Ford performance springs 1 answer
        Hi... do you stock the OEM of these product for the 2005? Searched the website no luck.... HELP 1 answer
        Will this work to replace the sock...or this product is for cars with lowering springs 1 answer
        I installed the SR 1.5 lowering springs with Koni shocks and struts. Question 1... Will these work in front with the Koni struts? Question 2... Had frt end aligned after the new springs and struts were installed. Will I need to have frt end aligned again if I can install these without removing the bottom bolts of the struts? Thanks! 1 answer
        Will these work with RTR lowering Springs. 1 answer
        I recently had my garage install a Steeda Level 1 coil-over setup, with 200 lb. springs forward and 175 lbs. rear. I lowered the front only about .75 inches and the rear about 1.5 inches. With the shocks set soft as possible, the ride is bouncy and harsh on bumps (probably bottoming out in the rear.) I know I can easily replace the rear jounce bumpers, but will this kit be usable with the steed coil-overs up front? 1 answer
        I recently installed this in my 2011 GT with the Koni STR.T's and SR lowering springs. As the car sits, I have about 1/4" of clearance, but I feel like the back end is louder and a little rougher going over the many dips and speed bumps that Arizona has to offer. Should these be trimmed for my application? 1 answer

            christmas came early for my cars ride!

            I wouldnt have figured these things would have altered anything. i noticed my originals looked like someone roughly hacksawed half of the height away. Had already went lowered Ford Racing Springs, then Koni Shocks and Struts, but didnt think about the bumpers. actually they probably affect like 10 of the ride, worst potholes, worst repairs which resemble speed bumps in gated neighborhoods. Really make a difference on the compression rebound action of the Koni's. You will not be dissapointed unless you live on a near race track road, Will not make any difference on a smooth surface.

            These fit the bill. Old bump stops were non-existent. Sp you can imagine the difference once I installed these. Riding on Cloud 9 now. Definitely recommend if you need new bump stops.

            Bump stops

            Great addition to add when you are rolling over bumps and your car is bottoming out hard. A must to replace on worn out stop from over the years. Great product if you are doing suspension work.

            Perfect replacements

            These are the perfect replacement for your worn out bump stops. Necessary for lowered vehicles as the rear axle will bottom out if your 1.5 inches or lower. Also keep the fronts in your struts or coilovers as you have less travel. This will stop them from bottoming out.
