914Rubber Fog Light Lens Tensioning Spring for Porsche 914 (1970-74)
Restore your Porsche 914’s fog lights with the 914Rubber Fog Light Lens Tensioning Spring (part number 914.631.924.10), designed for 914 models from 1970-74. This reproduction metal spring secures the Hella TN1-TN2 or TN4 fog light lens (914.631.930.10 or 914.631.913.11) to the housing, maintaining proper tension to prevent rattles and ensure a tight seal. Eight springs are required per car—four per fog light—compatible with the 110mm round Hella lamps used in early 914s and 914/6s.
PMB Performance, with over 20 years of Porsche 914 expertise, has partnered with 914Rubber for nearly two decades, selling more 914Rubber SKUs than any other retailer. Crafted from high-strength, corrosion-resistant steel, this spring withstands the 914’s front-end exposure to moisture, road salt, and temperatures up to 160°F near the bumper. Unlike factory springs that can rust or lose tension, this 914Rubber spring maintains consistent pressure, ensuring the lens stays secure under vibration from the 1.7L or 2.0L engine.
The fog light assembly, mounted behind the front bumper, relies on these springs to hold the lens against the gasket and housing, preventing water ingress that could corrode the 35W or 45W Phillips bulb socket or wiring. A weak or missing spring can cause lens misalignment, reducing light output or allowing debris to enter, risking electrical faults in the 12V system. This 914Rubber spring installs easily, hooking into the housing’s retaining slots, and pairs perfectly with the 914.631.961.10 retainer kit for a complete refresh.
