34 Inch Core Width Radiator for 1988-1993 Chevy C/K and Suburban LS LT Swaps
Swapping an LS or LT powerplant into a 1988-1993 Chevy C/K Series truck or Suburban can overwhelm the stock cooling system, and the 1988-1993 LS Radiator 34" Core Width (Auto Trans) delivers the extra capacity needed to keep temperatures stable. Featuring a full width 34 inch aluminum core, this radiator sheds heat efficiently while dropping directly into factory mount points without any modifications. With every joint fully TIG welded, corrosion resistance and a completely sealed finish ensure dependable performance during heavy towing or spirited driving.
Full Width 34 inch Aluminum Core for Rapid Heat Rejection
The generous 34 inch core increases the area available for heat exchange, allowing coolant to shed engine heat more efficiently during hard pulls or in hot weather. By maximizing surface contact between coolant and aluminum fins, this design maintains stable temperatures under sustained load. The all-aluminum construction not only speeds thermal transfer but keeps overall weight low, contributing to sharper throttle response. Swapping in an LS or LT without upgrading the cooling system can lead to overheating, but this core design ensures steady performance mile after mile.
Precision TIG Welded Tanks Deliver Leak Free Durability
Each joint on this radiator is completed with TIG welding to produce a consistent bond that stands up to constant vibration and temperature swings. TIG welding fuses the high-grade aluminum tanks and core into a single assembly, eliminating seals or gaskets that can fail over time. The result is a fully sealed structure that resists stress cracking and prevents coolant loss even under heavy towing or spirited driving. This manufacturing method ensures you spend more time on the road and less on maintenance.
Direct Bolt In Fitment for 1988 to 1993 Chevy C/K Series
Engineered to drop straight into the factory mounting points, this radiator requires zero drilling or frame modification. Fitment covers 1988 to 1993 Chevy C1500, K1500 and Suburban models with automatic transmission, so installation is fast and precise. By using stock hardware and alignment, the radiator maintains proper hose angles and fluid flow without custom brackets. This direct approach cuts installation time and reduces the risk of leaks or misalignment associated with custom fabrication.
Corrosion Resistant Coating Options Preserve Performance
To suit both classic restorations and modern builds, this radiator is available in bare aluminum or a durable black epoxy finish. The bare aluminum option offers natural oxidation resistance and a timeless appearance, while the black epoxy layer adds protection against chips and environmental elements. Both finishes maintain full thermal conductivity so there is no compromise in cooling efficiency. This choice lets builders match their vehicle's style without sacrificing performance.
