Core Functions

• Body Roll Reduction: The primary role of the anti-roll bar is to counteract “body roll” (the vehicle’s tendency to lean toward the outer side of a corner). When the vehicle corners, the bar twists (utilizing its torsional stiffness) to transfer force between the left and right wheels—preventing the outer wheel from compressing excessively and the inner wheel from lifting. This keeps the vehicle’s body level, improving driver confidence and reducing passenger discomfort.
• Handling Stability: By limiting body roll, the bar ensures the tires maintain maximum contact with the road surface during dynamic driving. This preserves traction (especially for the outer tires, which bear most of the cornering load), reducing understeer or oversteer and allowing for more precise steering control—critical for safe maneuvering at high speeds.
• Suspension Balance: Works in harmony with the vehicle’s springs and shocks to balance ride comfort and handling. Unlike stiffer springs (which can harsh the ride), the anti-roll bar targets only lateral forces (cornering) while preserving vertical compliance (absorbing bumps), ensuring a smooth ride on straight roads without sacrificing cornering performance.
• Load Distribution: During uneven road conditions (e.g., one wheel hitting a pothole), the bar helps distribute vertical loads evenly between the left and right wheels. This minimizes sudden weight shifts, preventing excessive tire wear and reducing stress on other suspension components (e.g., control arm bushings).

Compatible Vehicles

This Anti-Roll Bar (OE: 31451320) is tailored for Volvo’s modern crossover (XC60) and cross-country wagon (V90 Cross Country) models. Below is a consolidated list of variants and applicable years:

Notes: “XC60 (18-)” denotes the second-generation XC60 (launched in 2018), which shares suspension architecture with the V90 Cross Country. For 100% fitment accuracy—especially to distinguish front vs. rear anti-roll bars (some models use both) or trim-specific tuning (e.g., R-Design sport suspension)—confirm compatibility with your vehicle’s VIN (Vehicle Identification Number) or Volvo’s official service manual.
