Today on CJ Pony Parts, we're gonna make this 2013 Focus ST handle even better with a larger rear sway bar.

The Focus ST is a great handling car right from the factory, but there's always room for improvement and since we recently installed a Steeda front sway bar, it only makes sense to compliment it with Steeda's rear sway bar.

This Steeda rear sway bar is designed to fit the 2013 to 2018 Focus ST and it it features a larger 25.4 millimeter diameter. That's 70% stiffer than the factory bar, which reduces understeer and body roll for more control. It comes polyurethane bushings and brackets and it'll make this Focus ST handle like a champ. So, let's get to the installation.

Okay, so we're at the rear of the car. We have it up on the lift and we took the wheels off, now we're gonna disconnect the end link from the sway bar. Grab a 14 millimeter socket and remove the nut that connects the end link to the sway bar. If you try to remove the nut and the stud spins, put a 5 millimeter hex key in there and hold it in place.

Remove the four 13 millimeter bolts that secure the bushing brackets to the car. Pull down on the sway bar and then, you can disconnect it from the end links.

Here's a side by side comparison of the factory sway bar and the Steeda sway bar. As you can see, the Steeda one is significantly larger. Raise up the sway bar and get it onto the end links. Install your nuts onto the end link. Use the provided grease to lube up the bushing. Slide it over the sway bar and spin it around to make sure you have the grease all around the bushing.

Install the brackets and reinstall the factory hardware. Then, you can tighten your bolts. Then, you can move on to the end links. And, our installations finished.

Okay, we got our Steeda rear sway bar installed. The silver powder coat finish is looking really nice and it's really gonna compliment the front sway bar to make this thing handle really good. Installations super easy. All you need is a 13 and 14 millimeter socket a probably 45 minutes and before you know it, you'll be heading down the road.
