Features & Details

  • Minimize Vibration and Drive Line Movement
  • Adjustable Height - Perfect for Clearance Issues
  • High Quality Billet Aluminum Construction
  • Polyurethane Bushings
  • Includes Two Sets of Bushings - Red for Street, Black for Competition
  • Made in the USA
  • Fits 2015-2019 GT Mustangs
Minimize Vibration. The stock S550 Coyote motor mounts use natural rubber bushings that deteriorate and soften over time causing sloppy engine and drive line movement, but Steeda Heavy Duty Motor Mounts use high grade polyurethane bushings to reduce driveline movement with minimum vibration and will last years longer than rubber.

Adjustable. Steeda designed their Motor Mounts to be adjustable in 1/4" increments. They can be installed at the stock height or up to 3/4 of an inch lower to help alleviate clearance issues from aftermarket superchargers, intakes and strut tower braces.

Red or Black. Steeda includes two different durometer bushings with their Motor Mount Kits. The red bushings add great control with only minimal increase in engine/transmission vibration - ideal for the daily driver. The black bushings are harder for maximum control, but will significantly increase engine/transmission vibration - highly recommended for competition use only.

Superior Materials And Quality. Manufactured in the USA from high grade aerospace grade billet aluminum and industrial grade polyurethane for superior durability, these Steeda Heavy Duty Mustang Motor Mounts are much lighter and stronger than their stock rubber and steel counterparts to give you years of trouble free driving performance.

Application. This set of two Steeda Heavy Duty Adjustable Motor Mounts are specifically designed to fit the 2015-2019 GT Mustangs equipped with the DOHC 5.0L Coyote V8 engine.

    Great mounts but can only go 1/2 inch

    I put a Whipple on my 17. Wanted to get better mounts. I tried dropping it 3/4 but there are 3 nubs on the power steering where the oil pan will hit and cause massive NVH. Was dynamiting still felt it in my steering wheel shifter. Put the car back up and was checked clearance that's when I found it. Was so glad I found it before it put a hole in the pan. Great mount but would only drop 1/2 inch. Or grind down nubs if pan on 3/4. Hope this helps someone save a lot of time an energy.

    Massive Increase in Vibration and Harshness

    I installed a Supercharger Kit in my 15 GT that required I lower the engine 3/4". These Steeda Mounts advertise just that, and the description says"The red bushings add great control with only minimal increase in engine/transmission vibration - ideal for the daily driver." Boy I felt tricked. From the second I fired my car up, to the 5 miles I drove before pulling these things out, the car felt horrible. The dashboard, visor, steering wheel, and shifter felt like there was something horribly wrong. They shook, and the shakes got progressively worse up to 3k RPM (I didn't take it over that). Don't get fooled, try a different mount, these really add a ton of vibration/harshness all around, and I only tried them using the Red Bushings. Some people may like the car rattling every second, but I did not. I replaced them with a different brand 3/4" drop and while there is a slight increase in NVH, it is substantially better than these Steedas. I double checked everything, but found a thread on a Facebook Mustang Forum where others were discussing these mounts having a good amount of feel when the AC is turned on, and also having strong dashboard vibrations. One persons completely sheared in half after 1,000 miles of driving (this is subjective as I don't know how this person drives their car). After paying for install, and then paying for a different set of mounts to be installed, Steeda was generous enough to offer me 10 off my next order. Not to mention, they didn't allow the same review I wrote here to be posted on their product page. IF you are looking to retain a close to factory, but stiffer ride with aftermarket lowering mounts, be sure NOT to choose these, they are downright awful.

    Another quality Steeda product

    I purchased these engine mounts to create more hood clearance when I installed my Vortech JT trim supercharger kit on my 2016 Mustang GT. I ended up lowering the engine 1/2" but ran into problems with radiator clearance with the inlet tube to the supercharger. I cut down the lower radiator bushings and lowered the radiator to solve the issue. Overall the Steeda engine mounts are very good quality, installed easily, and worked just as described.

    Great product

    I really like these mounts. They stiffened up the drive line and help with shifting. They were pretty easy to install and will help when I supercharge my car. You can use the softer material for more firm. I used the red bushings which were soft. I didn't notice too much additional noise or vibration
