H&R Sport Sway Bar Kit – BMW 335i / 340i / 435i / 440i / M235i / M240i xDrive (F22/F3x, N55/B58)

OVERVIEW

H&R's Sport Sway Bar Kit for the xDrive six-cylinder F22, F30, F32, F33, F34 and F36 cars replaces the factory anti-roll bars with stiffer H&R bars, increasing roll stiffness to cut body roll and sharpen turn-in without lowering the car or affecting ride quality. It's available as a matched Front & Rear Set, or as a Front Only or Rear Only bar so you can tune the front-to-rear balance or upgrade one end at a time.

H&R's urethane/Teflon composite bushings are included with each bar; they resist squeaks and need no lubrication. The front bar has a 2-hole adjustable end so roll stiffness can be tuned.
