1955-1957 Chevy TriFive Radiator for LS and LT Engine Swaps
When planning an LS or LT engine transplant in your TriFive Chevy, the 1955-1957 Chevy Radiator (Manual Trans) puts reliable cooling front and center. Its TIG welded aluminum core and tanks deliver fast heat rejection while a fine tube and fin layout maintains stable coolant temperatures during spirited drives or heavy towing. The lightweight design complements manual transmission applications and helps preserve power for the street or track. Matching factory inlet, outlet and mounting positions on 150 210 Bel Air and Delray bodies, this radiator installs without cutting or custom brackets and resists corrosion from road salts and moisture thanks to its durable finish.
Precision TIG Welding for Leak Resistant Strength
Every joint on this radiator is crafted using manual TIG welding, a process that delivers exceptional accuracy at each seam. By fusing high grade aluminum with consistent penetration depth, the welds form a continuous bond that resists cracking when exposed to repeated temperature cycles. This method removes potential weak points where coolant could seep, ensuring the system remains airtight under high operating pressures. Whether you're cruising through summer traffic or pushing the limits on a track day, the reinforced weld structure maintains integrity without the need for frequent inspections or repairs.
High Conductivity Aluminum Core for Stable Engine Temperatures
At the heart of the design is a tube and fin core milled from premium grade aluminum, chosen for its blend of light weight and rapid heat transfer. As coolant enters the fine tubes, thermal energy moves swiftly into the attached fins where airflow from the front grille carries it away. This arrangement delivers consistent cooling under heavy loads, preventing hotspots that can lead to engine knock or overheating. For LS and LT engines operating under towing stress or spirited driving, the optimized core architecture keeps temperatures in check for reliable daily performance.
Direct Fit Design for Smooth Manual Transmission Integration
Engineered specifically for 1955-1957 Chevy 150, 210, Bel Air, and Delray bodies with manual transmission, this radiator aligns perfectly with factory mounting points. Inlets, outlets, and bracket positions follow original specifications so no cutting, drilling, or custom brackets are required. Installers benefit from a streamlined process that reduces the risk of misalignment and saves valuable shop time. The direct fit integration also ensures proper coolant flow routing and avoids clearance issues with existing frame rails and support brackets.
Protective Finish Options for Enduring Corrosion Defense
Choose between a natural bare aluminum surface or a robust black epoxy finish to match your restoration goals. The untreated aluminum highlights a classic metallic sheen while resisting rust in standard driving conditions. For harsher environments, the epoxy coating adds a dense protective barrier against moisture, road salt, and chemical exposure. Both finishes maintain the radiator’s structural integrity and aesthetic appeal, ensuring your TriFive project retains its period correct look and enjoys extended service life without compromise.
