LS and LT Radiator for 1988-1993 Chevy C1500/K1500/Suburban
Swapping an LS or LT powerplant into a 1988 to 1993 Chevy C1500, K1500, or Suburban often leads to higher engine heat, and this 1988-1993 LS Radiator 34" Core Width (Auto Trans) addresses that challenge. Engine cooling remains steady thanks to a full width aluminum core that installs using stock mounting points with no drilling required. Featuring a 34 inch core width, it delivers increased surface area for rapid heat rejection, while 100 percent TIG welded tanks ensure corrosion resistance and durability for C/K Series setups.
Precision TIG Welded Aluminum Tanks and Core
Every joint on this radiator is crafted with 100 percent TIG welding, delivering exceptional strength and a completely sealed finish for leak-free operation. TIG welding creates a uniform bond that resists stress cracking under the high vibration and temperature swings of an LS or LT swap. By fusing the high quality aluminum tanks and core in a single process, this radiator avoids weak points common in multi-piece assemblies and delivers reliable service mile after mile.
Full Width 34 Inch Core for Rapid Heat Rejection
The full width design expands the cooling surface to 34 inch, dramatically increasing the area available for heat exchange. This larger core area sheds heat quickly during hard pulls or stop-and-go traffic, keeping engine temperature within optimal range. As a result, you benefit from stable performance even when the engine is under maximum load or encountering high ambient temperatures.
Finish Options for Corrosion Resistance and Style
To match both classic and modern builds, the radiator is available in a bare aluminum finish or a black epoxy coating. The bare aluminum option offers a timeless look while naturally resisting rust, whereas the epoxy finish adds a protective barrier that wards off chips and oxidation in harsh environments. Both finishes preserve thermal conductivity so you never sacrifice cooling efficiency for durability or appearance.
Direct Bolt-In Fit for 1988 1993 Chevy C1500 K1500 Suburban
Designed for a drop-in installation, this radiator uses stock mounting points with zero drilling required, making it ideal for DIY enthusiasts and professional shops alike. Fitment covers 1988 through 1993 Chevy and GMC C1500, K1500, and Suburban models with automatic transmission. This direct approach reduces installation time and ensures proper alignment, so your swap stays on track without custom fabrication.
