Radiator for LS and LT Swaps in 1988-1995 Chevy/GMC C/K Trucks and SUVs
Anyone swapping an LS or LT V8 into a GMT400 Series C1500, K1500, Tahoe, Suburban or Yukon will find the 1988-1995 LS Radiator 28.25" Core Width Auto Trans delivers steady coolant temperatures under sustained towing or hot ambient conditions. Constructed around a TIG welded aluminum core and matching tanks, it resists stress cracking while speeding heat discharge from the coolant. The design matches factory mounting points so hoses and brackets align with original frame rails for a true drop in installation that keeps engine bay lines neat and fitment precise. Finished in bare aluminum or black epoxy, the radiator resists corrosion without hindering thermal transfer and helps maintain consistent gauge readings whether hauling heavy trailers or commuting on warm summer days.
Expansive 28.25 Inch Aluminum Core for Efficient Cooling
The 28.25 inch core delivers a large frontal area that accelerates transfer of heat from coolant to air flow. Dense fin arrays and optimized channel design maintain a steady fluid speed through the radiator, reducing hot spots under sustained load or trailer towing. This design keeps engine temperatures in check during long climbs in heat or during spirited acceleration on busy roads. Consistent gauge readings and quick temperature response help drivers trust their cooling system under all conditions.
Precision TIG Welded Aluminum Fabrication for Leak Free Strength
Every joint and tank seam on this radiator is fused using TIG welding, a process known for its clean weld beads and minimal material distortion. That level of precision reduces potential crack points under the varying pressures of performance cooling. By maintaining straight internal passages, it avoids flow restrictions that can lead to thermal spikes. Fabrication and inspection take place in the United States to ensure consistent quality and lasting service life.
Direct Fit for GMT400 Chassis with Original Mounting Points
This radiator installs directly into the frame rails of 1988 to 1995 C1500, K1500, Tahoe, Suburban and Yukon models without any cutting or bracket building. Inlet and outlet ports match original hose positions, allowing builders to reuse factory lines and keep the engine bay tidy. The direct design preserves chassis strength and balance when hauling heavy loads or during everyday driving. By removing the need for fabricating custom supports, installation time and effort are greatly reduced.
Choice of Bare Aluminum or Black Epoxy for Corrosion Resistance
Select the raw aluminum finish for its natural oxide layer and superior thermal transfer to air flow. The black epoxy option adds a durable protective layer against road salt, dirt and moisture without hindering heat exchange. Both finishes receive a uniform coating thickness to preserve core performance across the entire face of the radiator. This allows a long service life and reduced maintenance needs in harsh driving environments.
