Description

The H&R 20mm Rear Sway Bar is engineered to be a perfect complement to performance suspension setups like H&R Springs, Coil Overs, and Cup Kits. Its primary function is to significantly reduce body roll, enhance lateral stiffness, and ultimately improve overall vehicle handling. This upgrade is constructed from a special 50CrV4 spring steel, chosen for its high tensile strength, making it stronger and more resilient than many other sway bars. H&R utilizes proprietary bending machines to ensure complex curves are seamlessly integrated, guaranteeing a precise fit for compatible vehicles. The sway bar kit has undergone shot-peening and heat treatment for durability. It features precision forged ends, and many applications include multiple end link mounting points for adjustability. The kit also comes with H&R's exclusive bushings, made from a Urethane/Teflon composite that effectively prevents squeaks and requires no ongoing lubrication or maintenance. Simply bolt them in and experience improved performance. This non-adjustable rear sway bar has a 20mm diameter. It is designed for various BMW 2 Series (F22/F23) models from 2014-2021 and BMW 3 Series (F30/F31/F34) and 4 Series (F32/F33/F36) models from 2012-2019, covering a range of engines including 2.0L and 3.0L variants, and both standard and xDrive (AWD) configurations.
