Hidden behind the outer rocker panel, the inner sill plays a crucial role in maintaining the structural strength of your Holden HQ, HJ, HX, HZ or WB Series. When rust takes hold inside this boxed section — often caused by trapped condensation and long-term moisture build-up — proper repair means cutting out the weakened metal and welding in a solid replacement. This Sill Panel Repair Section is designed to restore that strength and integrity where it matters most.

Features:

• Inner Sill Structural Repair Panel: Fits behind the outer rocker panel, forming a critical part of the vehicle’s side body strength on either the left-hand or right-hand side.
• Restores Structural Integrity: Reinforces the cabin floor support and side chassis rigidity when original metal has been compromised by corrosion
• High-Quality Mild Steel Construction: Manufactured using quality mild steel to replicate traditional factory materials, ensuring compatibility for welding and finishing.
• Protective Coating: Supplied with a temporary anti-rust primer or storage coating to reduce surface corrosion during transport and storage. Note: Coating must be sanded or properly prepared before welding and final paint application.
• Professional Installation Ready: As a reproduction panel, it serves as a starting template. Minor trimming, edge-beating, shaping and alignment adjustments may be required during fitting to achieve factory-style gaps and body lines.
