Construction & Design

The BladeRunner Street Series Radiator is meticulously crafted using premium materials and precision manufacturing techniques. The core features a 2.2-inch tube and fin design that maximizes surface area for heat exchange, allowing the radiator to dissipate heat more efficiently than stock units. The end tanks are fabricated from thick 1/8-inch aluminum plates, providing superior resistance to cracking and corrosion under heavy use.

All joints and seams are 100% TIG-welded, a process known for producing strong, leak-proof welds that withstand vibration and thermal cycling common in diesel applications. The billet aluminum inlet and outlet fittings further enhance durability and ensure a secure connection to the cooling system hoses. The overall design maintains factory mounting points, preserving vehicle stability and simplifying installation.
