Energy Suspension Front Sway Bar Bushings for 06-11 Civic Si

Energy Suspension 28mm Front Sway Bar Bushings - 2006-2011 Honda Civic Si (FA5/FG2)

If your 06-11 Si feels sloppy in corners, or you're chasing that vague, floaty feeling through fast sweepers, worn OEM rubber sway bar bushings are usually what's behind it. This Energy Suspension set swaps that soft, degraded factory rubber for Hyper-Flex polyurethane, a material that holds its shape under sustained cornering load and doesn't pack down over time the way stock rubber does. The payoff is sharper turn-in, less body roll, and a front sway bar that's finally doing the job it was designed to do. It's a cheap upgrade you can knock out in your driveway, and you'll feel it the first time you lean on the car.

What Worn Rubber Bushings Are Costing You

Here's the deal with these. Your front sway bar ties your left and right wheels together to keep the car flat in a corner, but it can only do that if it's held tight in its mounts. When the factory rubber gets old and soft, the bar twists and deflects in that worn bushing instead of transferring force, so it's not actually controlling roll until you've already leaned over. That lag is exactly the floaty, disconnected feeling you're noticing. Firm up the mount and the bar locates properly, so it loads up right when you turn in instead of a beat later. You're basically getting closer to what the factory sway bar geometry was supposed to deliver all along, without having to step up to a thicker bar.

Why Hyper-Flex Poly Beats The Rubber

This is where the material actually matters. Polyurethane resists compression set, which is the fancy way of saying it doesn't flatten out and go sloppy after a few hard heat cycles like rubber does. It's a higher durometer than the factory stuff too, so the bar stays located even when you're really leaning on it in a corner. And it just lasts, way longer than OEM rubber, whether you're daily driving it or beating on it at a track day. Swap these in once and you're not thinking about your sway bar bushings again for a long time.

Easy Install, But Use The Grease

You're not tearing into the suspension for this. You unbolt the two front sway bar mounts, pull the old bushings off the bar, clamp these on, and bolt it back up, about an hour with hand tools. One thing you cannot skip: Energy Suspension includes grease that's formulated specifically for polyurethane, and you need to use it on the inside of each bushing. Skip the grease and these will squeak over every bump until it drives you up a wall. Grease them right and they stay silent and just do their job.

Pick Your Color

These come in two finishes, same bushing underneath, so go with whatever suits your build. Red is part number 16-5146R (SKU ENS-165146R) and black/green is part number 16-5146G (SKU ENS-165146G). Either way you're getting both the driver and passenger side bushings, so you're doing the full front sway bar mount in one shot.

Make Sure You've Got The 28mm Bar

These are a direct fit for the 2006-2011 Honda Civic Si, both the FA5 sedan and the FG2 coupe, which run a 28mm front sway bar from the factory. One thing to confirm before you order: these are sized for the 28mm bar, and the base and EX Civics of this generation may run a smaller bar, so if you're not on an Si or you've swapped your bar, measure your front sway bar diameter first and make sure it's 28mm.

Note: Energy Suspension 28mm front sway bar bushing set for the 2006-2011 Honda Civic Si (FA5 sedan and FG2 coupe), covering both driver and passenger sides. Made from Hyper-Flex polyurethane that resists compression set and holds the front sway bar firmly for sharper steering response and reduced body roll versus worn factory rubber, with much better durability in both street and track use. Available in red (part number 16-5146R, SKU ENS-165146R) or black/green (part number 16-5146G, SKU ENS-165146G). Polyurethane-specific grease is included and should be used on installation to prevent squeaking. Sized for the factory 28mm front bar, verify your front sway bar diameter is 28mm before ordering, as base and EX Civic models may use a smaller bar. One set per order.
