Steeda has once again taken the S550 Mustang to the next level of performance and comfort with their Adjustable Urethane Differential Mount Bushing Insert System. When Steeda’s engineers sat down to design this kit, their goal was to come up with a way to increase performance without sacrificing an ounce of drivability all while keeping the car quiet!

And they have succeeded in that. You know have the ability to minimize pinion angle changes, noticeably increase traction, and help eliminate wheel hop and differential deflection with this new kit. Made from high-strength urethane to Steeda’s exact specifications and durometers, this kit will arrive with 2 different bushing options. The red “Street” 80 durometer bushings and a black “Performance” 90 durometer bushings. Both bushing options will increase performance with no increase in NVH (Noise, Vibration and Harshness).

Steeda’s kit will add the strength and support the OEM bushings need to perform the way you have always hoped for. Remember, this is not a permanent modification. There is no drilling, cutting or pressing required. You’ll simply loosen and remove a few bolts and this kit will easily install in less than 1 hour. Bushings are included for both the front and rear differential mounting locations and Grade 10.9 hardware is included with zinc-plated washers.

Rated 4 out of 5 by from Worth the money, great performance I installed the red ones, I must say I love the ride, it did stiffen up the rear in a great way. I did gain some NVH, when I have load on the differential I can hear the gear whine transfer to car. When I get off the gas the whine stops, it’s not loud but it is annoying to me, my wife doesn’t seem to hear it so that’s good. The performance upgrade was completely worthwhile and I recommend the upgrade. I only gave it 4 stars because of the whine.

Rated 5 out of 5 by from Helps kill wheel hop combined with BMR CB005 I installed the BMR CB005 along with the Steeda Black Differential Inserts because I'm tired of wheel hop. Since the install, I have much more NVH such as more vibration through the shifter, crunching sounds of the drivetrain when pressing in the clutch and taking off at idle, and gear whine at around 60MPH. Installing the insert on the front of the diff by the driver's side slowed me down because it was very tight because of the gas tank shield being in the way and because OEM metal bushing collar protruded more than the passenger side one, but I was able to bang it in eventually. It took me 4 hours to do everything and using a motorcycle jack for the subframe positioning made my life a bit easier. I can still make the car wheel hop at will on the 1st to 2nd gear shift if I'm over 6K RPM and shifting aggressively. 3rd doesn't chirp anymore and it just pulls now. I feel about 85% of the wheel hop is gone now. The car feels much firmer and doesn't squat like it used to when launching. The rubbery feeling of the stock setup is gone and it feels far more solid. Now, I need to get better shocks and tires to further get rid of wheel hop.

Rated 5 out of 5 by from Great kit! Installed this along with the BMR rear cradle alignment and bushing lockout kit. I used the black race bushings. This will definitely change the feel and ride of your GT. Immediately noticed that the car just grabs and goes. No more mushiness on the backend, solid and planted feel under all conditions especially when hitting it hard. May be increased because of the BMR lockout kit but there is noticeable additional NVH. All kinds of little clunks and sounds that you did not hear or feel with the stock parts installed but that does not bother me. I am building a serious street car not a Cadillac. Beware the front driver side is not easy to get to if you are doing this in your driveway on jacks and jack stands like I did. You will need to completely remove 3 of the 4 subframe bolts and let the subframe hang way down there to get that one. It is a little uncomfortable and stressful to say the least when on your back in the driveway but it can be done and the effects are worth the effort.

Rated 5 out of 5 by from Hit the spot I already had all the other steeda goodies. Adding these got rid of the wheel hop but also the bouncing as you drive down the road went away. The install is a bit of a pain on jack stands but nothing you can't do.

Rated 5 out of 5 by from Helps with wheel hop I got these to combat the wheel hop and they have been working pretty well. Put the black ones in. Still have some wheel hop but not nearly as bad. Install isn't bad with the exhaust off
