Featuring our all new polyurethane bushings, Steeda's S550 Mustang Billet Aluminum Vertical Links provide less deflection than the rubber bushings in the stock vertical links, but do not add any NVH.

Made from 6061 aircraft grade aluminum, these links will keep your S550 wheel alignment dialed-in and help keep the power planted to the ground. The larger polyurethane bushings, combined with billet steel sleeves and spacers, offer more control through jounce and rebound while still offering plenty of compliance, causing absolutely no suspension bind or an artificial spring rate.

Our one-piece billet design is accurate down to one-thousandth of an inch (0.001"). The S550 Mustang geometry requires a precise length Vertical Link (something not possible with a welded design), as a either a longer or shorter piece will drastically degrade handling and stability.

These Vertical Links are an excellent component for road racers, giving better stability under severe and high speed hard braking.

Made in the USA and backed by a lifetime warranty, give your S550 Mustang the best parts possible go with Steeda, where Speed Matters

Vertical Links & Full Stop The Hop Installation On GT350

CA Residents: Cancer and Reproductive Harm WARNING

Hi everybody Brian from here today to speak to you about our Billet Vertical Links for the S550 Mustang. Let's begin with the purpose of the Vertical Links. On the independent rear suspension of the S550 Mustang. These link the lower control arm to the wheel carrier. They're mounted vertically and thus the name and the idea is to reduce the wheel from wanting to carry forward. It sounds kind of crazy but that's the easiest way to visualize exactly what's happening is you accelerate hard or if you're coming out of a corner hard and the idea here is to keep the geometry of the rear suspension in line under hard acceleration or hard cornering. In our other videos, we've talked a lot about how to reduce wheel hop. We have another great product for you that has two different options to suit your driving needs. Let's begin with the version of our vertical link they recommend for our drag racing enthusiasts. We put this one with Delrin Bushings that means zero deflection, immediate responsiveness great 60 foot times and improved grip because there's reduced wheel hop. And for our corner carver's out there, we offer a Polyurethane version. This utilizes a specific durometer that's a great balance between responsiveness. So under hard cornering and hard acceleration and under threshold braking the vertical links will keep the rear suspension geometry in check. The flip side to this is as you're going through the corners you're not going to be fighting the car continually trying to catch the back of it, because you know that you want the front of the car to come out of the corner before the back does. Both options for vertical links are constructed of CNC Billet Aluminum. This is important for a couple of reasons. It's lighter than the factory units and much stronger than our competitors that use welded ends which are subject to cracking over time. Furthermore we've designed our vertical links to pivot at the bushings. This is important because as your suspension moves up and down it can do so freely. Unlike the factory vertical links which will bind and cause an artificial spring rate. Also our vertical links have a lifetime warranty. We manufacture these in the USA at our Valdosta Georgia facility because Speed Matters! If you have any questions or comments please post below.

These are Great!
Start with these, greatly reduce wheel hop. Along with the IRS bushing lockouts I can barely ever get any wheel hop on the street. Fit and finish is exceptional, very high quality part.

Very best upgrade
If this is the one and only upgrade you can afford this should be it. You instantly notice the way the car pushes forward on launch and out of the corners. There is now zero flex at the rear.

2017 mustang gt premium with 725hp
I can't comment on this alone because I did everything at once, adjustable toe links, camber links, everything for rear subframe, spherical bearing on lower control arm, steeda driveshaft and McLeod twin disk clutch, barton hybrid 3 shifter. Now my stang is a freaking beast. Total transformation

Wheel hoop gone!
I just bought the vertical links with the Polyurethane Bushings because of the road track focus ( I have been experiencing terrible car rear dancing on hard braking at Road Atlanta Turn 10).I installed them in no time and left my old worn tires on and the grip was Amazing! Almost no wheel hoop which I have never felt this grip before. I'm looking forward to try them at Road Atlanta next Friday to test how the car behaves when braking before turn 10 from 148mph to 60mph.
