    Reduce Wheel Hop and Deflection. When warming up your Mustang's tires in the staging lane of your favorite drag strip do you experience unnecessary wheel hop? Well, almost all S550 drivers do. This is because the 2015 to 2019 Mustangs feature an Independent Rear Suspension (IRS) that is well known for deflecting under rapid acceleration causing loss of traction and excessive wheel hop at the track and on the street. By installing a BMR Suspension IRS Cradle Bushing Lockout Kit you will virtually eliminate all troublesome cradle deflection and see an increased improvement in rear wheel traction for more impressive tire smoking burnouts with no wheel hop.

    80%-90% Reduction In Deflection. The BMR IRS Cradle Bushing Lockout Kit uses lockout rings and locating washers to hold the IRS cradles inner sleeve bushings securely in place preventing the cradle from moving in any direction. During testing of the Lockout Kit, BMR documented an 80% to 90% decrease in fore/aft IRS cradle bushing deflection. A bone stock Mustang with no suspension modifications and factory tires will see a 90% or higher reduction in cradle deflection. Where a modified, more race oriented Mustang equipped with stickier performance tires will experience slightly less of a reduction. A BMR test vehicle launched at over 7000 rpm, on drag radial tires, saw about an 80% decrease in bushing deflection. Throughout the entire testing process BMR saw a 95% or higher decrease in vertical deflection under all testing conditions.

    Centers IRS Cradle. BMR's IRS Cradle Bushing Lockout Kit not only reduces deflection and wheel hop, but it also centers your Mustangs IRS cradle. Replacing the factory sheer plates, the included cradle braces perfectly centers the IRS cradle under the rear of your Pony. The frame side bolts of the brace locks the cradle securely in place, so that it does not move under any form of spirited driving.

    Superior Construction. BMR proudly designs and manufactures their IRS Cradle Bushing Lockout Kit right here in the USA. BMR's Lockout Cradle Braces are made from 1-5/8" diameter, heavy-wall DOM steel tubing for superior strength and extra rigidity. These Lockout Braces are then completed in a durable black hammer-tone powder coated finish for aggressive good looks and long lasting corrosion resistance.

    No Increase in NVH. BMR's IRS Cradle Bushing Lockout Kit was engineered to drastically reduce bushing and cradle deflection with little, to no change in NVH (Noise, Vibration and Harshness). Seeing that there is no noticeable increase in NVH, this BMR IRS Lockout Kit is perfect for street, auto cross and race applications.

    Simple Bolt-On Installation. Installation of the BMR Suspension IRS Cradle Bushing Lockout Kit can be completed in about two hours with just basic hand tools. This BMR IRS Lockout Kit utilizes the existing factory bolt holes, so no cutting, welding or extra modifications are needed. Please note that an alignment, by a qualified shop, is highly recommended after installation.

    Application. This Red BMR Suspension IRS Cradle Bushing Lockout Kit is designed as a direct bolt-on upgrade for use on 2015 to 2019 Fastback Mustangs equipped with the factory Independent Rear Suspension (IRS), including the V6, EcoBoost, GT and Shelby GT350 models. Not intended for use on Convertible models.

        Hi. Would you recommend changing the Rear Vertical Links to aftermarket at the same time? Thanks.

        • If you have really bad wheel hop it's not a bad idea. You definitely can't go too overboard with correcting the wheel hop so it definitely can't hurt. You could by this BMR IRS Cradle Bushing Lockout Kit first to see if it's satisfactory enough as you may decide you don't need to fix the issue any further. However, with that being said, as I mentioned earlier it certainly wouldn't hurt, plus it makes installation a lot easier to buy them together/makes the installation cost cheaper considering this would be one trip to the shop.

        I have an auto, stock tires, stock suspension, CAI/exhaust, no tune running 12.3s, will these make a difference for me? Only concerned with drag racing daily driving.

        • If you are looking to heat up your rear tires and get better launches off of the line, this will be a good addition for you as the lockout bushing kit will reduce cradle deflection and give you better traction. For daily driving however, there is no rear difference except for the reduction in wheel hop as well.

            Amazing bang for the buck!

            I was kind of sceptical as how this could reduce wheel hop. After about 200 miles now I can tell you that this is worth every penny. It doesn’t eliminate all of the wheel hop but definitely enough to put a smile on my face! Hard acceleration on a rough road is the true test. This should definitely be one of your first upgrades to your S550. With that said I had a MAJOR problem when installing these. A word of advice for anyone who does this upgrade, please be careful when threading the cradle bolts back in. I ended up cross threading one when getting it back in :( This resulted in me having to remove the entire cradle from the car just so I can get to the hole to re-tread it! After looking it up this has happened to several people out there. Thankfully the process of dropping the cradle is actually really simple. So when the directions say to use a pry bar to line the holes back up, definitely get it as close as possible. I would actually suggest to get some help to line things back up to get the bolt threaded easily.All and all this is a simple install and should only take a little over an hour.

            Install instructions

            The instructions do not mention the front bushing washers on the bottom of the front bushings. Some pictures of the install show them coming with the kit. My kit did not have them. The instructions leave you with a question mark as to what to do.

            A bit of improvement

            As far a I can tell this product has great potential, I mean the concept is perfect, but the product itself has different tube longitudes, it’s quite obvious when you put them together, but in the other hand has adjustable bolt holes so isn’t a big problem, but remember, take your time, my car was going sideways, so I found the issue and corrected

            The difference feels great. Rear end doesn't get all out of control anymore. It just plants and goes! I have nitto nt05s in the rear and they hook and I'm gone! Rear feels stronger. No more wheel hop! It's amazing. Great product! Install on a lift took maybe about an hour

            Finally installed these on my 15 Mustang and handles flat through turns when coupled with upgraded sway bars, shocks and diff bushings. Chirp tires from a dead stop and car takes off like a bat out of heck out of the hole...almost feels like driving a live axle on the straightaways. More control through turns!!!

            Made a very noticeable difference..

            Installed these myself, along with 2 rear Steeda inserts. Some suggest the inserts weren't needed as well, but I already had the set so installed 2 of them. After experiencing the tolerances of the car parts, and understanding better how this all works, it does seem like this kit from BMR is the best option possible to tighten up the movement in the rear cradle bushings, while centring it, without ANY noticeable NVH being added.

            Installed these with the Steeda Alignment Kit for BMR IRS and the rear does feel stiffer, pretty easy install if you have access to a lift, no wheel hopping so far but I also have the BMR vertical links, overall I don't regret buying, it's worth it

            Rather surprising

            Pretty easy kit to install. Took about 40mins on jack stands. Only perhaps arduous part may be lining up the big bolt holes, but even that may add perhaps 10 mins. This car is set up for pretty high level autocross competition at the national level. I always felt that IRS Mustangs have very sloppy feeling rear suspension. Way too much side to side and front to rear deflection. This kit really did eliminate a good deal of this. Acceleration is vastly improved with a dramatic reduction of wheel hop. Corner exit is improved since you can roll on the throttle pre apex with a pretty predictable reaction from the rear end. Overseer (drift) is a lot easier to throttle steer thru. I also added the Viking shocks and of course sway bars and end links and the total rework has made this GT a point and shoot terror in the autocross circuit.
