Precision TIG-Welded Aluminum Radiator for 1963-1966 C/K LS & LT Builds

Constructed from 100% TIG welded aluminum, this radiator maximizes heat rejection and cuts weight for reliable performance in LS and LT engine swaps on 1963 to 1966 C10, C15, K10, and K15 GM trucks. Manufactured in the USA with high-grade materials and precision craftsmanship for an exact C/KSeries fit, it is tuned for manual transmission cooling demands and delivers superior thermal efficiency, robust corrosion resistance, reduced maintenance, and lasting resale value.

1963-1966 C10/C15/K10/K15 Truck Radiator for LS and LT Engines

When you drop a modern LS or LT engine into a classic C10, C15, K10 or K15, this 1963 to 1966 GM Truck Radiator (Manual Trans) maintains consistent temperatures without fabrication hassles. Built with a full aluminum core and TIG welded tanks, it drops into the frame rails of a C/KSeries truck without trimming or custom brackets. Clear port connections and an optimized tube and fin layout ensure uniform coolant flow and prevent hotspots during towing or spirited drives. Arriving ready for manual transmission plumbing, it resists corrosion from road salt and moisture so you can focus on the swap instead of cooling worries.

Precision TIG-welded Construction for Leak-Free Performance

The radiator's tanks and core are joined with 100% TIG-welded seams that create deep bonds through controlled heat application. This process eliminates weak points common in other joint methods and withstands repeated pressure cycles and engine vibrations. Smooth welds reduce potential debris traps and require minimal cleanup after assembly. As a result, this craftsmanship delivers impressive durability under demanding towing conditions or spirited road runs.

Full Aluminum Core Offering Rapid Heat Rejection

Built entirely from premium aluminum, the core uses the metal's natural ability to transfer heat quickly from the coolant to the atmosphere. An optimized tube and fin arrangement ensures consistent flow across the entire surface, preventing hotspots that can strain engine components. By maintaining stable operating temperatures, the radiator helps to preserve the LS or LT engine's lifespan even when you are hauling heavy loads. This design also reduces overall weight compared to traditional copper cores without sacrificing strength.

Dual Finish Options for Corrosion Resistance and Style

Select the natural bare aluminum finish, which forms a passive oxide layer to guard against moisture, or the black epoxy treatment for an extra barrier against road salt and debris. Each coating is applied evenly to ensure full surface protection and strong adhesion through repeated heat cycles. The epoxy option also enhances the classic look under the hood without drawing attention away from your truck's original lines. Both finishes maintain long term integrity and preserve resale appeal.

Factory Style Fitment for Installation Simplicity

Engineered to drop directly into the stock frame rails of 1963 to 1966 C10, C15, K10, and K15 trucks, this radiator requires no trimming or custom brackets. Hose connections line up precisely for manual transmission plumbing, which reduces the possibility of leaks or routing errors. Its dimensions respect factory firewall clearance and allow retention of the original fan shroud. This direct fit design streamlines the swap process so you can focus on tuning rather than fabrication.

For the same radiator but with fans, consider our 1963-1966 GM Truck Radiator (Manual Transmission) with Fans and trust in its reliable cooling performance for your LS or LT swap.
