Eibach Anti-Roll Sway Bar Kit for 22-26 Civic Si/Integra

Eibach Anti-Roll Sway Bar Kit - 2022-2026 Honda Civic Si (FE1) & 2023-2026 Acura Integra (DE4)

If you've ever pushed your Si or Integra hard into a corner and felt the body lean and the front tires start to give up, that's the exact feeling this kit fixes. The Eibach Anti-Roll-Kit is a matched front and rear sway bar set that ties the car down flat, cuts the body roll, and puts more of your tire on the road when it matters. The result is a car that feels planted, sharp, and way more composed when you drive it like you mean it, without changing a thing about how it rides in a straight line.

Fits The Si And Its Integra Twin

This kit covers the 2022-2026 Honda Civic Si and the 2023-2026 Acura Integra in Base and A-Spec trim. That's no accident. The Integra is built on the same platform as the Si, essentially its more upscale sibling, so they share the suspension these bars are designed around. One kit, tuned for both, whether you're running the Si or the DE4 Integra.

What Sway Bars Actually Do For You

Here's the plain version. When you turn hard, the car's weight shifts and the body rolls onto its outside tires, which unloads the inside ones and costs you grip. Sway bars fight that roll, keeping the car flatter so all four tires stay planted and working. Flatter cornering means more stability, quicker turn-in, and more grip to lean on, so you corner faster and the whole car feels tighter and more connected. It's one of the biggest handling improvements you can bolt on for the money, and unlike springs or coilovers, it does its work without affecting your straight-line ride quality at all.

Adjustable So You Can Tune The Balance

This is where the kit gets really good. Both bars are adjustable, so you're not locked into one setting. The front bar is tubular and 3-way adjustable, and the rear bar is tubular and 2-way adjustable. That matters a lot on a front-wheel-drive car like the Si and Integra, which tend to understeer, meaning the front wants to push wide in a corner. By firming up the rear bar, you dial out that understeer and wake up the car's rotation, so it turns in eager instead of plowing. You can set it mild for a planted daily feel or firm for a car that rotates on command, then change your mind later. It's real tuning built into a bolt-on part.

Tubular Bars, Made In The USA

Eibach builds these bars tubular rather than solid, which is a smart piece of engineering. A tubular bar gives you the stiffness you want while shaving weight compared to a solid bar, so you get the handling gain without adding unnecessary pounds. The front bar measures 29mm and the rear comes in at 22mm, sized specifically for this platform rather than pulled off a universal shelf. Eibach makes them right here in the USA and backs the kit with a five-year warranty, so this is proven hardware, not a gamble.

Works With Your Setup, Stock Or Modified

One of the best things about this kit is how well it plays with everything else. Eibach engineered and tested it for these cars specifically, and it's built to work whether yours is bone stock or already lowered on springs or coilovers. So if you're running the factory suspension, these bolt right up and sharpen it. If you've already dropped the car, they stack on top of that to further flatten the body roll. Either way, they slot into your build instead of fighting it.

Do The Job Right

These are a straightforward bolt-on, but a couple of things make the install go smoothly. Take your time getting the endlinks and mounts torqued properly, and start with a middle or milder adjustment setting so you can feel out the balance before you go aggressive. Then drive it, and if you want more rotation, firm up the rear a notch. Dialing it in over a few drives is half the fun of running an adjustable kit, so don't just set it and forget it right away.

Who This Is For

This one's for the Si or Integra owner who actually drives the car and wants it to handle like the sport compact it's meant to be. Whether you're carving backroads, chasing cones at an autocross, or just want your daily to feel tighter and more planted, this front-and-rear kit gives you a big handling upgrade plus the adjustability to tune the balance exactly how you like it. Bolt them on, set your starting point, and go find out how flat your car can corner.
