ACDelco Suspension Control Arm Heat Shield

ACDelco Suspension Control Arm Heat Shields

Where a control arm sits close to the exhaust, catalytic converter, or other hot components, a heat shield keeps radiant heat away from rubber bushings, ball joint boots, and nearby lines and wiring. ACDelco's suspension control arm heat shield offering addresses exactly this job: a small, easily overlooked stamped component that helps protect the parts around it from premature heat damage.

Why the Heat Shield Matters

Control arm bushings and ball joint boots are typically made of rubber or elastomer compounds. Prolonged exposure to high radiant heat can harden, crack, or degrade them, which can lead to looseness, noise, uneven tire wear, and alignment drift. A properly positioned shield reflects and deflects that heat, helping preserve the suspension components it covers. If a shield is bent, corroded, rattling, or missing after previous repairs, replacing it is a simple way to restore the original thermal protection.

The ACDelco Advantage: GM Heritage

ACDelco is General Motors' own parts brand. GM Genuine Parts and ACDelco work together as the only source for true General Motors Original Equipment and aftermarket parts. That lineage matters for a component like a heat shield, where precise shape, mounting point locations, and clearance around the control arm and exhaust all determine whether the part works as intended.

ACDelco's catalog is organized into tiers. GM Genuine Parts or ACDelco Original Equipment are the true OE parts installed during production or validated by GM for Chevrolet, Buick, GMC and Cadillac vehicles. Beyond OE, ACDelco Gold and Silver premium lines are the only aftermarket parts backed by GM. Gold, formerly known as the Professional line, is positioned as the high-quality alternative to OE parts. Silver, formerly the Advantage line, is a quality high-value option.

What to Check When Choosing a Heat Shield

• Position: Confirm whether your vehicle needs a front or rear shield, and which side or control arm (upper or lower) it protects.
• Fit and mounting: Match mounting holes, tabs, and fasteners to your vehicle's year, make, and model so the shield seats without contacting moving parts.
• Condition of nearby parts: If the shield is damaged, inspect the adjacent bushings, ball joint boots, and brake or fuel lines for heat wear while the area is accessible.
• Hardware: Replace worn or rusted clips and bolts at the same time for a secure, rattle-free installation.
