Energy Suspension 28mm Sway Bar Bushings for 06-11 Civic

If your 06-11 Civic Si is feeling sloppy in corners or you're chasing down that vague, floaty feeling through sweepers, worn OEM rubber sway bar bushings are usually the culprit. The Energy Suspension 28mm front sway bar bushing set (16-5146R in red, 16-5146G in black/green) replaces the soft, degraded factory rubber with Hyper-Flex polyurethane - a material that holds its shape under sustained lateral load and doesn't pack down over time the way OEM rubber does.

The result is sharper turn-in, reduced body roll, and a sway bar that's actually doing the job it was designed to do. A worn bushing lets the bar twist and deflect instead of transferring force - swapping to poly gets you closer to what the factory sway bar geometry was intended to deliver, without having to upsize to a thicker bar.

These are a direct fitment for 2006-2011 Honda Civic Si models (FA5 and FG2 chassis). The set covers both driver and passenger side, so you're replacing the full front sway bar mount in one shot. Available in red (part number 16-5146R, SKU ENS-165146R) or black/green (part number 16-5146G, SKU ENS-165146G).

Why Hyper-Flex polyurethane over OEM rubber:

• Polyurethane resists compression set - it doesn't flatten out and get sloppy after a few heat cycles
• Higher durometer than factory rubber means the bar stays located, especially under hard cornering
• Outlasts OEM rubber significantly in both street and track use
• Energy Suspension includes their own grease formulated for polyurethane - use it, or the bushings will squeak

Fits:

• 2006-2011 Honda Civic Si (FA5 coupe, FG2 sedan) - 28mm front sway bar
• Verify your front sway bar diameter is 28mm before ordering - base and EX Civic models may run a smaller bar
