This H&R non-adjustable sway bar kit pairs a 28mm front and 18mm rear bar for 1996–2003 BMW 540i E39 applications as a matched front-and-rear anti-roll solution. Supplied together to provide coordinated roll-stiffness changes across both axles, the kit is intended to fit the E39 540i using factory mounting locations and to alter handling balance in a predictable way.
