Description
Product Overview
The Chevrolet GMC 2500HD and 3500HD hub seal from REPLACEMENTKITS.COM is engineered to deliver a precise, leak‑free fit for model years 2020 through 2025. Constructed from premium rubber, the seal provides excellent resistance to oil, water, and dust, ensuring long‑lasting protection for your vehicle’s front axle assembly. Each package includes two seals, each weighing just 0.64 ounces, and they are sized to match the original equipment specifications for part numbers 84080139 and 290‑308. The rubber compound maintains its flexibility across a wide temperature range, from –40°F up to 225°F, which means it can handle the harshest winter roads as well as scorching summer heat without cracking or hardening. The design incorporates a reinforced lip that seats securely against the spindle hub, creating a barrier that prevents fluid loss and contamination of the bearing surfaces.
