Whiteline BTR65Z 18mm Heavy Duty 3-Point Adjustable Rear Sway Bar Kit

The Whiteline BTR65Z is an 18mm heavy duty, 3-point blade adjustable rear sway bar kit engineered to reduce body roll and activate more grip during cornering. Sway bars are the primary suspension component designed to control body roll — and upgrading to a larger, higher-quality bar is one of the most cost-effective handling improvements available for any vehicle.

By increasing rear roll stiffness, the BTR65Z spreads lateral cornering loads more evenly across the tires, delivering measurably better grip and improved handling balance. Critically, these gains come without sacrificing ride quality or comfort on the street.

Key Features:

• 18mm solid spring steel construction — manufactured from premium Australian-grade spring steel for superior torsional strength and fatigue resistance
• 3-point blade adjustable — forged blade ends allow roll stiffness to be fine-tuned by selecting from multiple lever arm positions, without replacing the bar
• Heavy duty design — larger diameter provides significantly higher torsional resistance than OEM bars, reducing body roll force requirements
• Silver powder coat finish — electrostatically applied and heat-cured for a hard, corrosion-resistant skin tougher than conventional paint
• Synthetic elastomer mounting bushes included — high-performance bushings with internal bore knurling and grease retention lips for optimum lubrication and long service life
• Complete DIY bolt-on kit — includes the sway bar, mounting hardware, and all necessary components for a straightforward installation
• 3-year warranty — Whiteline performance products are backed by a 3-year warranty from the date of original installation

Whiteline adjustable sway bars allow the driver to dial in handling balance to suit their driving style or conditions — whether that's daily street use or weekend track performance. The stiffer the setting, the more force is required to move the left and right wheels relative to each other, directly reducing the vehicle's tendency to body roll in corners.

The BTR65Z is part of the broader Whiteline handling system, designed to integrate with Whiteline chassis bracing and alignment products for a fully balanced suspension solution. A wheel alignment is recommended after installation.
