LS and LT Radiator for 1967-1987 C/K Series Trucks and Blazer/Suburban
When swapping an LS or LT powerplant into C/K Series trucks or Blazer and Suburban models from 1967 through 1987, the 1967 through 1987 GM Truck Radiator 18.5 inch Tall for manual transmission delivers a true OEM height drop-in fit to preserve original mounting points and coolant line routing. Constructed entirely of aluminum, this radiator core resists corrosion and sheds heat rapidly under towing or daily driving conditions. With zero fans included, it bolts to factory brackets and supports mechanical fan drives without interference. Available in bare or black epoxy finish and made in the USA, it ensures reliability and straightforward installation.
Optimized Cooling for Classic GM Trucks
The 1967 to 1987 GM Truck Radiator 18.5 Inch Tall for manual transmission applications delivers a direct upgrade to original equipment cooling capacity. Designed with a standard cooling core height of 18.5 Inches, this radiator enhances coolant flow through increased fin density, helping maintain optimum engine temperature under both daily drive and towing conditions. Its precise core dimensions match the factory opening, ensuring a clean install without any need for custom trimming or shims. By supporting LS and LT powerplants in their stock and mildly modified forms, this radiator delivers stable operating temperatures even when engine output is increased or ambient heat is intense.
Aluminum Construction for Weight Savings and Durability
Constructed entirely from premium aluminum, this radiator offers significant weight reduction over traditional copper brass units while resisting corrosion in all road conditions. Aluminum’s superior thermal conductivity accelerates heat transfer from coolant to airflow, improving overall cooling efficiency. The robust welds and thick-tube design enable reliable performance under pressure while minimizing the risk of leaks. Every radiator is crafted in the USA, adhering to strict quality control measures that guarantee tube alignment, consistent fin height and firm header structure for long service life and repeatable temp control.
Seamless MuscleRods Mount Integration
When installed alongside MuscleRods engine mounts, this radiator provides exact alignment with the front crossmember and fan shroud of your GM truck project. The engineered fitment ensures that fan clutch and shroud positions maintain ideal clearance and that coolant lines route without kinks or stress points. This compatibility preserves proper engine placement and drivetrain angles, crucial for smooth transmission input shaft alignment and minimal vibration. Whether you are performing a late model engine swap or restoring an early model frame, the synergy between this radiator and MuscleRods components simplifies installation and safeguards against common cooling system fitment challenges.
