MOFORKIT Third Brake Light Seal Gasket for Chevy Silverado & GMC Sierra (2014–2019)

Overview

Upgrade your third brake light with MOFORKIT’s gasket, built from thicker EVA foam to cushion the light housing while creating a sturdier, more dependable seal against the elements. This design targets common trouble spots on compatible trucks, including 2014–2018 Chevy Silverado 1500 and 2015–2019 Silverado 2500HD/3500HD, as well as GMC Sierra 1500, 2500HD, and 3500HD models. The result is a seal that helps guard the interior from water ingress and dust intrusion, while maintaining a clean appearance that blends with original lighting.

By prioritizing durability and ease of maintenance, MOFORKIT aims to reduce ongoing upkeep. The gasket’s reinforced foam also helps absorb minor vibrations, which can contribute to a steadier light assembly during driving, especially on rough roads or in challenging weather. The single-sided adhesive design lets you remove and re-seat the seal during bulb replacement or light assembly maintenance without harming the gasket itself, preserving its performance over time.

Key benefits

• Thickened EVA foam delivers improved waterproofing and dustproofing compared to the factory seal.
• Flame resistant, chemical resistant, and durable construction for long-term reliability in demanding environments.
• Precisely engineered to fit both factory and aftermarket third brake lights without requiring trimming.

Tips for best results: ensure both the vehicle body and the third brake light surfaces are clean before applying the gasket, and verify alignment to avoid gaps.
