1968-1982 C3 Headlight Bearing Stop Collar 3926235 - OEM Number(s) (3926235)
Keep Your Corvette’s Headlights in Line—Literally
Your C3 Corvette’s hideaway headlights are a signature feature—but behind that smooth flip-and-turn action is a crucial part doing some heavy lifting: the Headlight Bearing Stop Collar. This component controls the rotational stop point of the headlight assembly, ensuring your headlights open to the correct position—no more, no less.
Designed as a direct replacement for original GM part number 3926235, this bearing stop collar restores precision to the headlight mechanism, keeping everything aligned and operating smoothly. Without it (or with a worn one), you risk misaligned beams, mechanical strain, or even full-on failure of the headlight door system.
Why It Matters:
Your Corvette’s vacuum headlight system relies on exact tolerances. The stop collar keeps the headlight assembly from over-rotating or slamming into its housing, protecting the entire linkage and motor setup from premature wear or damage. Replacing a worn collar can save you from a much bigger—and more expensive—repair down the road.
