Whiteline BNR45Z Rear Sway Bar 20mm Heavy Duty 3-Point Adjustable

The Whiteline BNR45Z is a 20mm heavy duty 3-point adjustable rear sway bar engineered to reduce body roll and significantly improve cornering performance. Built from high-grade spring steel, this sway bar is a direct upgrade over the factory unit, delivering a noticeable improvement in handling balance, stability, and driver confidence.

Sway bars work by resisting the rotational forces that cause a vehicle's body to lean during cornering. By limiting body roll, lateral loads are distributed more evenly across the tire contact patches, increasing grip and improving overall handling response. The Whiteline BNR45Z takes this further with its 3-point adjustable design, allowing the bar's effective stiffness to be tuned to match different driving preferences or conditions — without replacing the entire bar.

Key Features:

• 20mm diameter heavy duty construction for increased torsional stiffness over the OEM bar
• 3-point adjustability — tune roll stiffness by selecting from three lever arm positions
• Manufactured from high-grade spring steel for long-lasting strength and durability
• Reduces body roll for flatter, more controlled cornering
• Improves tire contact and wear by keeping tires more upright under load
• Enhances handling, safety, and stability without sacrificing ride quality or comfort
• Includes mounting hardware — sway bar mounts feature internal bore knurling and grease retention lips for optimum lubrication and performance
• Lateral locks prevent sideways movement of the bar under cornering loads

The Whiteline BNR45Z is covered by Whiteline's national warranty program and is designed for straightforward installation using standard tools.
