Eibach Rear Sway Bar Brace Kit for 16-21 Civic

Eibach Rear Anti-Roll Bar Brace for 2016-2021 Honda Civic - Part #AK41-40-036-05-RA

A bigger rear bar only works as well as what it is bolted to, and on the 10th gen Civic the rear bar mounting takes a real beating once you step the bar rate up. Eibach's answer is this kit: a steel reinforcement brace and backing plate that tie the rear bar mounts into the rear subframe, plus a set of adjustable end links. The brace spreads the load so the bar works the suspension instead of flexing sheet metal, and the end links let you set sway bar preload properly so the bar is not fighting itself at ride height.

Eibach thinks enough of this hardware that it packages the same brace and link set with its 25mm rear bar option for the Type R. Sold on its own here, it does the same job behind any upgraded rear bar on the FC/FK chassis: sharper response from the bar you already have, a stiffer load path, and preload you can actually adjust after the car is aligned and settled.

Specifications

Fitment

This brace kit covers the 2016-2021 Civic in every body style, trim, and engine, Si and Type R included. It reinforces the rear bar mounting on any 10th gen running an upgraded rear anti-roll bar.

What to Know Before You Buy

This kit does not include a sway bar; it reinforces the mounting for one. If you are ordering an Eibach rear bar package for this chassis, check what is in the box first, since some Eibach rear bar part numbers already include this brace and end link set and there is no reason to buy it twice. Set end link length with the car at ride height on its wheels, then torque everything to spec.
