Steeda IRS Subframe Alignment Kit for all 2015, 2016, 2017, 2018, 2019 and 2020 Mustangs.

The team over at Steeda went hard to work coming up with a simple solution the moment they noticed a lot of people were having issues with their 2015-2020 Mustang's rear subframe being misaligned from the factory. This kit from Steeda guarantees that your S550 Mustang's subframe will be bolted to the same location every time it is lowered, thus eliminating the need for multiple unnecessary alignments!

Unfortunately, the subframe mounting holes found on the 2015-2020 Mustang are very large in comparison to the subframe mounting bolts. Since there is a significant difference in the size of the bolt versus the hole size, the subframe can potentially be misaligned to the left or right up to a 1/2" from the factory. The Steeda IRS Subframe Alignment Kit is made from CNC-machined Delrin. The Delrin sleeves will slide into your subframe mounting holes to fill the extra space left between the subframe mounts and the factory mounting bolts that attach to the rear subframe.

Features and Benefits:
- Easy Do-It-Yourself Upgrade
- Does Not Require Any Permanent Modifications
- No Additional Hardware Needed for Installation
- Top-Notch CNC-Machined Delrin Construction
- Aids in Perfect Alignment of the Rear Subframe to Chassis
- Absolutely No Increases in NVH (Noise, Vibration and Harshness)
- Made in the USA

*This Kit from Steeda will fit all 2015-2020 EcoBoost, V6 and GT Mustangs.

Please Note: Like with many suspension components, CJ Pony Parts highly recommends getting an alignment after installation. Mainly due to the fact that your subframe could have been misaligned from the factory and with it now being squared in the chassis, some adjustments might need to be made.

There is no shortage of Mustang aftermarket parts manufacturers vying for your business these days. While many of these companies specialize in the production of certain Mustang parts, they are unable to cover your part needs on a bumper-to-bumper basis. Steeda is a Mustang parts manufacturer that offers everything you need for whatever year Mustang you may own and CJ Pony Parts offers a huge selection of Steeda parts to meet your specific performance and styling needs.

Rated 5 out of 5 by from Easy Install but..... Easy install but do not be one of those people who do not read instructions. These units only go one way and the front and rear are different.

Rated 5 out of 5 by from Genius AGAIN, these should have been inserted at the factory, but we're not that lucky. Such a simple way to help maintain the alignment of your subframe I can't believe I didn't think of this. Definitely LOOSEN all four blue subframe bolts at once and then insert the alignment tubes one at a time. Easy install and straight forward. They are two different sizes though so look them over first.

Rated 5 out of 5 by from Solution for oversize OEM bushings Installed these with a couple other mods at the same time. Install was super easy and fit great. Keeps the rear subframe from moving too much. Only downside I can see is the loss of adjustability in the rear cradle if needed down the road.

Rated 5 out of 5 by from Steeda - Steeda Rear Subframe Alignment Kit IRS 20 Fitted them this weekend, the sub frame alignment was good so they fitted straight in. Nice snug fitment, well made and good material. Quite easy to do, the most challenging part was torqueing the bolts with the exhaust system in place.

Rated 5 out of 5 by from Smart thing !! Where simple to install once you have noticed that there are two different diameters for front and rear. But now it's on and the alignment is done.

Rated 5 out of 5 by from Great Product After watching some videos and looking at other reviews, it's a no brainer. You have to get it when lowering your car.

Hi I've just bought it, is it necessary to use the bushings part 555-4437 with it or can we use it separately?

Asked by: Vince68
Although it is not necessary it would be a good time to do both at the same time.

I've noticed my drivers side wheel sticks out a little further than the passenger side after lowering. Would these help correct that, it's very minimal and the wheel offsets are the same.

Asked by: Sdoc8865
Chasing are that your rear sub-frame is misaligned. If that is the case, these will help correct that.
