H&R Sport Sway Bar Kit – BMW 530i / 540i RWD (G30, B48/B58)

OVERVIEW

H&R's Sport Sway Bar Kit for the rear-wheel-drive G30 530i and 540i 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. This is the rear-wheel-drive kit for cars without Active Roll Stabilization; xDrive cars take 72654-2.
