H&R Sport Sway Bar Kit – BMW 330i xDrive/M340i xDrive/430i xDrive/M440i xDrive (G20/G22, B46/B58)

OVERVIEW

H&R's Sport Sway Bar Kit for the xDrive-equipped G20/G22/G23 3 and 4 Series upgrades both the front and rear anti-roll bars over the factory units, increasing torsional stiffness to reduce body roll under cornering load. A stiffer bar keeps more of the tire's contact patch planted through a corner, sharpening turn-in and giving the chassis a flatter, more controlled feel without altering ride height.

The kit is a direct bolt-on using the factory mounting locations and reuses the factory end links, and both bars are multi-hole adjustable so the front-to-rear roll-stiffness balance can be tuned to the driver's preference. This is the xDrive-specific part number, engineered around the all-wheel-drive front subframe and suspension geometry; the rear-wheel-drive versions of these same models take a different H&R part number.

Installation

• Illustrated fitting instructions are included in the box with the sway bar kit. H&R does not publish a separate per-application installation PDF for this sway bar; the technical sheet linked below covers spring-specific topics (bumpstop trimming, spring identification) and is not applicable to this sway bar.
• H&R Warranties & Claims (PDF) — official H&R warranty terms, coverage periods and claim procedure.

• Fitment confirmed against MAPerformance, Gumotorsport and Throtl listings for part number 72462-2, which list 330i xDrive, M340i xDrive, 430i xDrive and M440i xDrive. This is the xDrive-specific counterpart to part 72462 (RWD) — do not use on a rear-wheel-drive 330i, M340i, 430i, or M440i.
