HR Springs Sway Bar Kit for 02-04 Acura RSX

H&R Sport Sway Bar Kit for 02-04 Acura RSX Base and Type S

Upgrade only the front sway bar on an RSX and you add understeer. Upgrade only the rear and the car rotates more, but the body still leans, and the strut front still loses camber on the outside tire. Doing both ends together is how you get the car flatter overall without throwing the balance off. H&R's kit pairs a 26mm front bar with a 20mm rear bar, sized to work together. The RSX rolls less at both ends, the outside front tire stays more upright in a corner, and the car turns in faster without adding understeer.

From the driver's seat, the RSX feels tighter and more responsive. It leans less, settles faster in quick transitions, and holds its line through a corner instead of pushing wide. Ride quality stays close to stock. Sway bars only work when the two sides of the car move differently, so bumps that hit both wheels at once feel the same as before. A pothole that hits one wheel comes through a little more. For a street RSX that sees canyon roads or the occasional autocross, it's one of the best handling upgrades for the money.

Bushings That Don't Need Grease

Polyurethane sway bar bushings usually need grease, or they start squeaking within a few months. H&R's bushings use a urethane and Teflon composite. Teflon is slippery enough that the bar rotates smoothly without any lubricant, so you skip the greasing at install, they don't collect road grit, and you don't have to come back and re-grease them later. They're firm enough to hold the bar tight to the chassis, so it starts working as soon as the body begins to roll.

Adjustable Ends

The bars have forged ends, made as one piece with the bar, with no welds to crack. On applications with more than one end link hole, you can change the bar's stiffness by moving the link. A shorter lever arm makes the bar stiffer. That lets you fine-tune the balance between the front and rear. Start in the softest holes and go stiffer one step at a time.

Install Notes

Plan on most of an afternoon with jack stands. The rear bar is the easy one. The front bar runs close to the subframe and steering rack, so you may have to drop the subframe slightly or work the bar out at an angle. Don't grease the H&R bushings, since they're made to run dry. Tighten the end links with the suspension at ride height, then cycle the steering from lock to lock and make sure nothing touches the bar.
