LS and LT Radiator for 1970-1981 GM A-Body and 1978-1988 G-Body Vehicles
When installing an LS or LT V8 into a 1970 to 1981 Camaro or a 1978 to 1988 G Body chassis the stock cooling system often hits its limits and this radiator provides a direct solution. It uses a fully TIG welded aluminum core and tanks to speed heat rejection and resist corrosion under spirited driving. Installation relies on factory frame rails and upper mounts so no cutting or custom brackets are required. Technicians will appreciate the precise fit with 4L60E and 4L80E transmission lines and consistent coolant pressure even during heavy use.
Precision TIG Welding for Durable Aluminum Construction
The radiator core and tanks are joined using 100 percent TIG welding, creating seamless connections that resist the constant vibration and temperature swings inherent to spirited driving. By employing pure aluminum in every joint, heat conductivity remains consistent across the entire assembly, preventing localized hot spots near the engine block. This welding technique also eliminates weak points where cracks or leaks might begin, ensuring stable coolant pressure under heavy load. Manufactured domestically under strict quality protocols, each weld is inspected for uniformity, contributing to a service life that meets the demands of LS and LT V8 swaps.
Efficient Heat Rejection for LS and LT V8 Engines
The internal tube and fin arrangement has been carefully engineered to maximize surface area for rapid thermal transfer. Coolant is guided through a sequential flow path that matches the heat output profile of modern LS and LT engines, preventing temperature spikes during acceleration or towing. This design preserves the viscosity of transmission fluid in 4L60E and 4L80E units, promoting consistent torque converter performance. As a result, engine components are subject to fewer thermal cycles, reducing metal fatigue and maintaining optimal power delivery under sustained use.
Corrosion Protection with Bare Aluminum and Epoxy Coatings
Owners may choose the natural bare aluminum finish, which resists moisture and can be polished to a factory style shine, or select a black epoxy coating for an added barrier against road salts and grime. The epoxy encapsulates every surface, sealing microscopic pores that can otherwise initiate oxidation. Both finishes are applied in a controlled environment to maintain uniform thickness and adhesion, ensuring that corrosion resistance starts on day one. This flexibility allows builders to match either a classic polished look or a stealth appearance while preserving core integrity.
Seamless Installation with Factory Frame Rails and Transmission Lines
This radiator is designed to drop into place using existing frame rails and upper mounts on 1970–1981 Camaro and 1978–1988 G-Body chassis, eliminating the need for cutting or custom bracket fabrication. It lines up precisely with factory transmission cooler ports on 4L60E and 4L80E configurations, reducing hose routing complexity and minimizing leak points. The direct fit approach shortens installation time and keeps the classic engine bay layout intact. Technicians benefit from repeatable alignment and consistent coolant flow path without additional modifications.
