Frequently Asked Questions
Does the H&R 70426 front sway bar require new end links on the BMW M5 E60?The HRS70426 is designed to use the factory OEM end links. New end links are not required unless the originals are worn or damaged.
Does this sway bar change ride height on the BMW M5 E60?No. The H&R 70426 is a direct replacement for the factory front sway bar and does not alter ride height. It only increases front sway bar stiffness to reduce body roll.
Is the 70426 adjustable?No. The HRS70426 is a non-adjustable sway bar. H&R offers an adjustable rear bar for the E60 M5 (part number 71426) which can be paired with this front bar for a complete sway bar upgrade.
Do the H&R polyurethane bushings on the 70426 require grease?No. H&R's exclusive Teflon-lined polyurethane bushings are permanently lubricated and do not require grease at installation or during ongoing service.
Will the H&R 70426 make the BMW M5 E60 harsh or stiff on the street?Upgrading to a stiffer front sway bar increases lateral stiffness and reduces body roll without stiffening the springs. Most drivers describe the result as a more connected, flatter driving feel with no meaningful increase in ride harshness over bumps or road imperfections.
Can I install the 70426 front sway bar without also upgrading the rear?Yes. The H&R 70426 front bar can be installed alone. However, pairing it with the H&R 71426 adjustable rear bar creates a balanced front-to-rear roll stiffness ratio for the best handling balance on the E60 M5.
Is the H&R 70426 legal for street use in the USA?Yes. Sway bar replacements do not require emissions or safety certification in the USA and are legal for street use.
What tools are required to install the H&R 70426 on a BMW M5 E60?Installation typically requires a floor jack, jack stands, sockets in various metric sizes, a torque wrench, and a Torx set to remove the factory sway bar hardware. A bushing press or rubber mallet is helpful for pressing in the new polyurethane bushings.
Installation Instructions
- Safely raise the vehicle and support on jack stands.
- Remove the front wheels for easier access to the front subframe area.
- Disconnect the factory sway bar end links from the sway bar at both ends.
- Remove the factory sway bar mounting bracket hardware and lower the factory sway bar from the mounting points.
- Install the H&R Teflon-lined polyurethane bushings onto the H&R 70426 sway bar at the factory mounting positions.
- Position the H&R 70426 into the factory mounting locations and install the mounting bracket hardware.
- Reconnect the factory end links to the sway bar ends.
- Torque all fasteners to factory specification.
- Reinstall the front wheels and lower the vehicle.
- Test drive and verify no squeaking or abnormal noise from the front sway bar area.
