1963-1982 C2-C3 Headlight Adjuster Spring 5949989 - OEM Number(s) (5949989)

Keep Your Corvette Headlights Secure and Aimed Correctly
Factory-style adjuster spring for proper headlight capsule mounting on 1963–1982 Corvettes.

This spring mounts the headlight capsule to the housing just like the original. Without it, the capsule can shift and your beams wander. Built to GM specifications for secure fit and correct tension on C2 and C3 headlight assemblies.

Fits the Following Corvette Models

  • Corvette (C2) 1963–1967

  • Corvette (C3) 1968–1982

Material / Finish

  • Metal spring with corrosion-resistant finish.

Dimensions

  • 1 11/32 inches long × 1/2 inch coil diameter × 1/16 inch hook diameter (34 mm × 13 mm × 1.5 mm).

Features / Benefits

  • Correct headlight adjuster spring for C2 and C3 Corvettes.

  • Mounts headlight capsule securely to housing to maintain proper alignment.

  • Factory tension ensures headlights stay aimed on the road.

  • Correct for late 1963 Corvettes with metal headlight buckets.

  • GM reference part number 5949989.

  • Sold individually, two required per headlight capsule.

Because Details Matter
Hook the spring into place, feel it draw the capsule tight to the bucket, and know your headlights will stay aimed where they should. Original-spec hardware keeps your beams steady at speed—because details matter.
