Types of Raw Materials Used in Sway Bars (Anti-Roll Bars)

1. Steel (Most Common)

Carbon Steel – Standard material for OEM applications, offering high strength and durability.

Alloy Steel – Enhanced with chromium or molybdenum for better fatigue resistance (common in performance vehicles).

2. Hollow Metal (Weight-Saving Option)

Hollow Steel Tubing – Reduces weight while maintaining rigidity (used in motorsports).

Aluminum Tubing – Lighter but less stiff than steel (found in some aftermarket kits).

3. Composite Materials (Specialized Use)

Polyurethane/Plastic – Used in RC cars (e.g., Traxxas models) for adjustable stiffness.

Carbon Fiber – High-end applications where weight reduction is critical (rare due to cost).

4. Adjustable Aftermarket Components

Anodized Aluminum End Links – Corrosion-resistant and lightweight (common in upgrade kits).

Note:

Street cars typically use solid steel sway bars for reliability.

Racing/off-road vehicles may opt for hollow or alloy steel for weight savings.

RC models often use plastic/composite bars for tunable flexibility.
