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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFront bar: 34mm, hollow, multi-hole adjustable\u003c\/li\u003e\n\u003cli\u003eRear bar: 25mm, hollow, multi-hole adjustable\u003c\/li\u003e\n\u003cli\u003eConstruction: cold-formed tubular steel, protective finish\u003c\/li\u003e\n\u003cli\u003eIncreases torsional stiffness front and rear versus the factory sway bars to reduce body roll\u003c\/li\u003e\n\u003cli\u003eDoes not change ride height, spring rate, or damping\u003c\/li\u003e\n\u003cli\u003eSold as a complete Front \u0026amp; Rear Set only\u003c\/li\u003e\n\u003cli\u003exDrive application only\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eH\u0026amp;R front and rear adjustable sway bars\u003c\/li\u003e\n\u003cli\u003eNew mounting bushings and hardware included\u003c\/li\u003e\n\u003cli\u003eSee the fitting instructions supplied in the box for the full bill of materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003ch3\u003eAdditional Parts Required\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNone.\u003c\/strong\u003e H\u0026amp;R's sway bar kit ships complete with the bushings and hardware needed for installation; the factory end links are reused.\u003c\/li\u003e\n\u003cli\u003eInstaller-supplied tools: jack and stands, standard hand tools, and a torque wrench.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eIllustrated fitting instructions are included in the box with the sway bar kit.
