Van Wezel 3003.02 Rocker Panel

Van Wezel 3003.02 Rocker Panel

The Van Wezel 3003.02 Rocker Panel is a high‑performance component designed for automotive body repair and restoration. It serves as the primary structural element that connects the front bumper to the vehicle’s chassis, providing both rigidity and impact resistance. This panel is engineered to meet the exacting standards of modern automobile manufacturers, ensuring seamless integration with the original design.

Key Functionalities

• Impact Absorption: The rocker panel’s geometry distributes collision forces across a broader area, reducing stress on adjacent body panels and preserving structural integrity.
• Structural Support: It acts as a load‑bearing member that maintains the alignment of the front bumper assembly during manufacturing and in service conditions.
• Corrosion Resistance: The panel is fabricated from high‑strength steel with an advanced protective coating, safeguarding against rust and extending vehicle lifespan.
• Precision Fit: Designed to match OEM specifications for a variety of Mercedes‑Benz models, the panel ensures a flush finish without gaps or misalignments.

Material Composition

The Van Wezel 3003.02 Rocker Panel is manufactured from high‑yield steel alloy (ASTM A572 Grade 5), chosen for its superior tensile strength and fatigue resistance. The surface undergoes a multi‑step coating process, including:

1. Pre‑Treatment: Mechanical cleaning to remove mill scale.
2. Electrolytic Passivation: Enhances corrosion protection.
3. Powder Coating: Provides a durable, color‑matched finish that resists chipping and fading.

Compatibility and Application Scope

The rocker panel is specifically engineered for the following vehicle families:

• Mercedes‑Benz models with chassis codes 8x, 9x, and 10x.
• 4‑door configurations requiring a right‑side exterior mounting.

Its dimensions and mounting points are calibrated to fit seamlessly into the existing body architecture, eliminating the need for extensive modifications. The panel can be used in both new vehicle assembly and as a replacement part during repair or refurbishment projects.

Installation Guidelines

1. Preparation: Clean the mounting area of any debris or old adhesive residue. Verify that the bumper frame is free from damage.
2. Alignment: Position the rocker panel against the chassis, aligning all reference marks with the vehicle’s alignment guides.
3. Screwing Sequence: Tighten mounting bolts in a cross‑pattern to ensure even pressure distribution. Use torque specifications provided by Van Wezel (typically 45–55 Nm).
4. Sealing: Apply automotive sealant along the joint edges to prevent water ingress and improve aerodynamic performance.
5. Final Inspection: Check for proper flushness, absence of gaps, and secure fastening before proceeding with bumper attachment.

Maintenance Tips

• Inspect the rocker panel annually for signs of corrosion or impact damage.
• Avoid prolonged exposure to harsh chemicals; clean with mild soap and water only.
• If paint chips appear, reapply a matching powder coating patch to maintain aesthetic consistency.
