Anti-roll bar diameters

Volvo 700/900 models have different anti-roll bar diameters depending on model and engine: Front: 24-28 mm (depending on variant) Rear: 16-20 mm (depending on variant)

Safely raise the car and remove the wheel. Locate the anti-roll bar (sway bar) which runs across the suspension. Use a caliper or micrometer to measure the rod diameter.

Yes, upgrading to a thicker anti-roll bar reduces body roll during cornering and improves handling. Common upgrades go from 24 mm to 26 or 28 mm on the front.

Consult your Volvo service manual or contact a Volvo specialist for exact specifications matching your model year and variant.

A stiffer anti-roll bar provides firmer cornering response, reduced body lean, and improved handling balance, especially when paired with upgraded suspension components.
