LS and LT Radiator for 1955-1957 Chevy TriFive 150/210/Bel Air/Delray
When transplanting an LS or LT into a 1955 to 1957 Chevy 150, 210, Bel Air or Delray with automatic transmission, the 1955-1957 Chevy Radiator (Auto Trans) ensures consistent coolant management by fitting directly into the original frame mounts. Crafted in the USA from high quality aluminum, it features 100% TIG welded tanks and core to resist leaks and thermal stress. Compatible with both LS and LT powerplants, the radiator offers a choice of bare aluminum or black epoxy finish while matching stock hose locations and shroud brackets. With zero fans built in, builders can select preferred fan assemblies without custom brackets, preserving underhood clearance and appearance for any TriFive restoration or custom project.
Precision Craftsmanship
At the heart of the 1955 through 1957 Chevy Radiator for automatic transmission is a fully TIG welded aluminum assembly. Each tank and core element is formed from high grade sheet stock. This welding approach yields uniform joins free of porosity and thermal distortion. The seamless connections heighten structural strength and foster efficient heat transfer under sustained highway or track driving.
Optimized Thermal Control
Engineered specifically for LS and LT powerplants, this radiator balances core thickness with fin density to lower coolant temperatures and resist boiling under load. An integrated passage handles automatic transmission fluid flow, reducing the need for extra external coolers. The design sustains consistent thermal regulation during towing or spirited acceleration, preventing performance loss caused by heat soak.
Seamless Integration with MuscleRods
This unit is sized to align precisely with MuscleRods mounting system. By matching their bracket points it secures the radiator at ideal height and tilt. This synergy preserves proper engine placement while maintaining optimal driveline angles. Installers benefit from drop in fitment and simplified hose routing when combining these components in period correct restoration or modern build application.
American Made Reliability
Manufactured in the USA each radiator undergoes a multi point inspection to validate weld integrity and flow performance. The high grade aluminum alloy resists corrosion common in older steel units and reduces overall weight. Backed by top tier customer support this product delivers long service life and peace of mind for enthusiasts who demand classic style with contemporary engineering.
