28.25in Core Radiator for 1988-95 C/K GMT400 LS and LT Swaps

For sustained heavy-duty cooling in 1988 to 1995 C/KSeries GMT400 OBS swaps, the 28.25 inch aluminum core drops into factory mounts to deliver fast heat rejection and steady temperature control. Precision TIG welded aluminum tanks and core resist corrosion, reduce system weight and simplify installation for reliable performance, long service life and enhanced resale value on C1500, K1500, Tahoe, Suburban and Yukon platforms.

1988-1995 Chevy C1500/K1500 Trucks, Tahoe, Suburban, GMC Yukon LS and LT Swap Radiator

Fitting an LS or LT engine into a GMT400 C1500, K1500 or SUV often pushes the stock cooling system past its limits under load and elevated temperatures. This radiator's 28.25 inch wide aluminum core for manual transmission applications spreads heat across a large area to maintain stable coolant temps during towing and spirited acceleration. Precision TIG welded aluminum tanks and core deliver strong joints that resist cracking under thermal cycling and vibration. Radiator mounts directly to factory supports on 1988 through 1995 Chevy C1500, K1500, Tahoe, Suburban and GMC Yukon models while cooling hose connections align with stock locations for dependable service in salt and moisture rich conditions.

Core Surface Expansion and Airflow Synergy

The 28.25 inch core width dramatically increases the surface area in contact with incoming air, allowing the system to draw heat away from coolant at a faster rate. This broader expanse works with natural airflow to create a more uniform temperature gradient across the core. Aluminum's high thermal conductivity ensures rapid spread of heat toward the fins where it is released into the passing air. By optimizing the shape and density of the core channels, hot spots are minimized under towing or spirited pulls. The design reduces reliance on auxiliary coolers, making the system more streamlined and reliable for LS and LT engine conversions.

Precision Welded Aluminum Construction for Engine Swap Durability

Every junction between tank and core uses TIG welding to form uniform, high integrity seals that resist vibration and thermal stress. This welding method applies a focused arc and filler material to maintain the original strength of the aluminum without introducing weak zones. The continuous weld beads also prevent the formation of microscopic leaks that can arise from repeated heating and cooling cycles. This approach extends service life in demanding truck and SUV applications where chassis flex and engine movement are more severe. It delivers a robust base that stands up under towing loads and off road excursions.

Corrosion Guard Coatings for All Season Protection

Users can choose between a classic bare aluminum finish or a black epoxy layer that acts as a barrier against moisture and road salt. The bare surface allows for quick visual checks and relies on aluminum's natural oxide layer for rust resistance. The epoxy alternative adheres firmly through the weld joints and core openings, shedding debris and shielding the metal under harsh environments. Each finish is applied evenly to avoid blocking fins or impairing heat transfer. This flexibility ensures reliable operation year round while preserving core efficiency.

Stock Mount Integration for Swift Installation

Designed to drop into the factory brackets on 1988 to 1995 Chevy C1500, K1500 and related SUV models, this radiator eliminates the need for custom supports or filler neck mods. Hose connections and mounting tabs align precisely with original locations to maintain correct routing and tension. This direct fitment cuts installation time and reduces margin for error during engine swap projects. By preserving stock geometry, coolant flow remains consistent with the vehicle's original design. The result is a neat installation that performs reliably without extra trimming or welding.

Count on robust construction and reliable cooling performance. For the same radiator but with fans see our 1988-1995 LS Radiator 28.25" Core Width (Manual Transmission) with Fans.
