[More Info]
A 2-piece inner and outer beltline molding kit engineered to restore the factory appearance and protect the door edge on 1978 Silverado and Sierra models. These precisely formed moldings replace worn, bent, or corroded trim to re-establish correct fit, seal, and visual continuity along the beltline. Constructed from corrosion-resistant metal with a factory-style finish, the kit provides durable protection against road debris and weather while delivering an OEM-like look. Designed for straightforward installation, it’s ideal for restoration projects or routine trim replacement to maintain value and curb appeal.
Features:
  • Fits 1978 Chevrolet Silverado and GMC Sierra models (inner and outer beltline molding, 2-piece kit).
  • Corrosion-resistant metal construction with factory-style finish for long-lasting appearance.
  • Replaces worn or damaged beltline trim to restore correct fit and seal along the door edge.
  • Helps protect bodywork from chips, moisture intrusion, and vibration-related damage.
  • Designed for easy, direct replacement — ideal for restorations and maintenance.
Installation / Application:
  • Difficulty: 2/5
  • Estimated time: 30-60 minutes
Suggested Tools:
  • Flat and Phillips screwdrivers
  • Plastic trim removal tool
  • Socket set or nut driver (common sizes)
  • Clean cloth and isopropyl alcohol
  • Small pliers
Instructions:
  1. Park vehicle on a level surface and open the door(s) where the molding will be replaced.
  2. Carefully remove the old molding: use a trim tool to pry away trim and a screwdriver or socket to remove any fasteners or screws.
  3. Remove any clips or adhesive residue from the mounting flange. Use pliers to pull old clips and a clean cloth with isopropyl alcohol to clean the surface thoroughly.
  4. Dry-fit the new inner and outer moldings to confirm alignment and clip/fastener locations before final installation.
  5. If the kit uses retaining clips, install clips onto the new molding or onto the vehicle flange as required. Replace broken or missing clips with new ones for secure mounting.
  6. Align the molding at one end and press firmly along the length to engage clips, or install screws/fasteners where applicable. Work end-to-end to avoid gaps or buckling.
  7. Verify an even gap and flush fit along the beltline. Re-tighten any fasteners and trim excess material if necessary.
  8. Close and open the door to ensure there is no interference. Re-clean the area and touch up any minor finish blemishes as needed.
