Dinan Adjustable Rear Sway Bar 17mm for E39 BMW 5 Series and M5
Dinan E39 rear sway bar replaces the stock rear anti-roll bar on the E39 5 Series and M5 with a stiffer 17mm unit that reduces body roll and sharpens rotation, with three mounting positions so you can tune the balance to your driving style. It’s a simple, single-component upgrade that noticeably tightens up the rear end of the car without touching the front suspension.
Features
- Solid 17mm rear anti-roll bar, a meaningful step up in stiffness from the factory bar
- Three-position adjustability lets you dial in more or less rotation depending on preference
- Reduces body roll for flatter cornering and more mechanical grip at the limit
- Straightforward install with roughly 1 hour of labor, since it’s a rear-only bolt-in swap that doesn’t require dropping the subframe
Applications
- BMW 5 Series: E39 | 1997-2003 | 3.0L I6 M54
- BMW M5: E39 | 2000-2003 | 5.0L V8 S62
Notes
- Rear bar only; pair with a front bar for a complete kit. Fits all E39 5 Series engines and the S62 M5.
Frequently Asked Questions
- Does the Dinan E39 rear sway bar fit the E39 M5? Yes. This exact part is sold for the full E39 5 Series lineup, and Dinan lists it directly on their BMW M5 parts page as well, so it’s compatible with the S62-powered M5 in addition to the six-cylinder and V8 5 Series models.
- Is the Dinan E39 rear sway bar compatible with all E39 engines, like the 525i, 528i, 530i, and 540i? Yes. Dinan’s own fitment data for this part doesn’t restrict by engine, so it covers the full range of E39 5 Series engines from the M52 and M52TU inline-six through the M54 and the M62/M62TU V8 in the 540i.
- What does the 3-position adjustability do on the Dinan E39 rear sway bar? The bar has three mounting positions, letting you choose between a milder factory-like feel and a firmer, more aggressive setting that sharpens rotation and reduces body roll for spirited driving.
- How difficult is installing the Dinan E39 rear sway bar? This is one of the simpler suspension upgrades Dinan offers. It’s a direct bolt-in swap for the factory rear bar with a documented labor time of about 1 hour, and it doesn’t require dropping the subframe like a front-and-rear kit would.
- Does the Dinan E39 rear sway bar include the front sway bar too? No, this is the rear bar only. If you want a front upgrade as well, check Dinan’s catalog for a matching front anti-roll bar for the E39 platform.
