Description


Steeda Adjustable Motor Mounts for your 2015+ S550 Mustang GT or GT350 directly replace the weak factory hydra bushing engine mounts. While the factory mounts get the damping job done, they can be prone to fatigue and sagging even with only limited hard use.

In addition to being much more durable than the factory engine mounts, these Steeda Adjustable Motor Mounts for the 2015+ S550 Mustang GT and GT350 are adjustable from factory height up to 3/4 of an inch lower to create clearance for superchargers and strut tower braces.

Steeda Adjustable Motor Mounts also feature dual durometer bushing packages. Choose the softer red bushings for great control with only minimal increase in engine vibration transmission. Choose the hard black bushings for maximum control, but will increase engine vibration transmission significantly. Black bushings package is highly recommended for competition use only.

Product Benefits

  • 3/4" height adjustment range
  • Adjustable in 1/4" increments
  • High quality billet construction
  • Made in the USA by Steeda

Hi everybody Brian from Steeda, spotlighting our Adjustable Engine Mounts for the S550 Mustang GT as well as the Shelby GT350 and 350R. The advantage of installing the Steeda Adjustable Engine Mounts is two-fold, One you gain performance and Two you gain the ability to adjust the engine height within the engine bay. Let's start on the performance side. From a performance standpoint the Steeda mounts are far more responsive than the factory pieces because of the use of polyurethane pucks or engine mounts if you will. The polyurethane is a higher durometer but not such a high durometer that's going to create a ton of vibration back in the cabin. Now we do want to warn our viewers that it will create a little bit of noise vibration and harshness (NVH) even with the red inserts or the softer durometer inserts that said, it's mostly just that an idol when you're cruising you won't notice it and more importantly when you're shifting it you're only going to notice the positive aspects of this. With every kit we also include a set of black bushings or pucks if you will and these are higher durometer than the red version. This is perfect for those of you running high horsepower applications or going to the racetrack a lot, or ultimately doing both. Ultimately what this means is better power transfer as you're shifting instead of being absorbed that energy goes directly through the driveline and that means immediate shifts immediate responsiveness that means tenths of a second are taken off your lap times, your autocross times or your ETs and the other major advantage height adjustability for the engine. This is very important for those of you that have added a Supercharger or a Cobra Jet Intake Manifold, Long Tube Headers, a different Steering Rack or all of the above and we know that you all have thrown a lot of different combinations at your S550 and actually this is a really great point to tell us how are you utilizing the Steeda Adjustable Engine Mounts. Please comment below. The idea here is to be able to set the engine height in the engine bay where you need it. Whether it's to clear the steering universal or the headers or the relationship between those two things. The Adjustable Engine Mounts will allow you to do this. Each of these spacers will allow you to adjust the height by one quarter inch. You have to be careful as you're lowering the engine not to go too low because especially with an aftermarket steering rack there's a chance that the oil pan will get too close, cause some vibration and other issues so please take note as you're lowering the engine as to how far you can go also pay close attention to that steering universal as we mentioned but each of these spacers is a one-quarter inch increment and that allows you to set it exactly where you want it to be. Another standpoint of the adjustability is lowering the center of gravity we always come back to the performance thing because Speed Matters. The reality is we want to help you go faster. We want to see your lap times come down. We want to see your auto cross times improve we want to see your ETs improve and your 60 foot times come down. Installation is really straightforward and no modifications are needed to the car. These also are compatible with the Steeda drag racing and road racing K-Members which is really important to those of you planning the next steps as you're going or if you've already gone to the K-Member, these mounts will also work with that. We do recommend professional installation because the engine does need to be supported while you're installing them. We also recommend re-torquing them periodically because again we know you're throwing a lot at your car and utilizing it for more than just well a daily driver. Like all Steeda products we only use the highest grade of materials. The spacers are Billet Aluminum and the engine mounts themselves are constructed of high grade steel and then plated for corrosion resistance. This is really important from a strength and durability standpoint of course they're backed by our lifetime warranty because we know you're going to throw some of the same things at them that we do. Whether it's in our Silver Bullet running the quarter mile and trying to set world records as well as our number 20 SCCA Road Race Car. If you'd like to see more about how we're putting these mounts through their paces as well as the other things that we're testing out on Mustangs definitely check us out on Social Media.

incredible feel
Was a bit nervous putting these in my '17 GT PP. My drivetrain was very stiff (1pc Steeda drive shaft, black poly bushings in the diff, Tri-Ax shifter with stiffer bushing, trans mount bushing, and the full stop the hop kit). Installed a twin disc solid hub clutch with aluminum flywheel last fall when the stock clutch failed on track and had chatter, howl/NVH issues. Put these engine mounts in with the red bushings 1/2" lower than stock height and vibration is DOWN significantly. No more chatter, crisp shifter engagement, and instant throttle response. Car feels epic. Be aware, I tried lowering the engine the full 3/4", but the steering gear was touching the oil pan. There isn't supposed to be clearance issues, but that was the reason I set it at 1/2". Car feels very nimble. Wouldn't go back and would highly recommend.

Steeda s197 motormounts
Just installed steeda motormounts. Very happy with them.i installed them along with blowfish trans mount and new MGW shifter. I can hit 3rd and 5th no problem. I had mgw shifter first had problems then blowfish trans bracket much better but last was steeda motormounts they made a big difference. So far so good. I don't hold my breath when going in to 3rd now.

Adjustable motor mounts
Had a little issue with my supercharger hitting the hood. Had these installed and lowered engine .5 inch. Took care of the clearance issue. Used the black bushings for high horsepower application an there is a little vibration in the steering, however not to bad to live with. Excellent quality of product and great service from Steeda. Thanks

Good
Picked these up to try. Had read some good things about solid motor mounts. Was getting some false knock on shifts and wasnt sure if engine movement during shifts was causing my issue. Anyways about an hour or so on jack stands and hand tools. First start up and up to about 30mph was a little more vibration but after about a week i cant tell the difference anymore. Seems to be less false knock on shifts now. Car seems marginally more planted during corners. I lowered 1/4 and used the red pucks for daily driving. No complaints so far and seem like well engineered materials.
