FAQ
Do these springs fit other vehicle brands?
While the springs are optimized for Chevrolet, Cadillac, GMC, and Oldsmobile models, they may be compatible with other makes that use a similar headlight adjustment mechanism. Verify the part number with your vehicle’s service manual.
Can I install the springs without removing the headlight assembly?
Yes, the springs are designed for direct replacement. You can access them by removing the adjustment screws and the existing spring without taking off the entire headlight housing.
How do I know if the springs need replacement?
Signs of wear include reduced headlight height adjustment range, visible deformation, or a noticeable drop in beam intensity. Replacing the springs restores proper alignment and beam focus.
Is any special tool required for adjustment after installation?
Only a standard Phillips or flat‑head screwdriver is needed to turn the headlight adjustment screws and set the desired beam level.
