1988-1995 Chevy C/K GMT400 LS and LT Swap Radiator
For enthusiasts fitting an LS or LT engine into a GMT400 Series Chevy or GMC truck the 1988-1995 LS Radiator 28.25" Core Width (Auto Trans) solves the cooling challenges posed by increased output and payload demands. Built around a 28.25 inch core with full TIG welded aluminum tubes and tanks this radiator resists cracks while accelerating heat rejection from the coolant. Its drop in form matches the factory mounting points on C1500, K1500, Tahoe, Suburban and Yukon models so there is no need for cutting or relocating brackets. Available in bare aluminum or black epoxy finishes it delivers corrosion resistance and steady performance whether towing heavy trailers or commuting on hot summer days.
28.25 Inch Core Maximizes Heat Rejection Efficiency
The expansive 28.25 inch aluminum core vastly increases the frontal contact area, accelerating the transfer of heat from coolant to airflow. By expanding the frontal contact area the radiator accelerates cooling as air passes through dense fin arrays. Optimized coolant channels reduce pressure drop and promote a steady flow rate, which lowers thermal spikes during sustained towing or spirited acceleration. Whether climbing steep grades in hot climates or handling heavy duty towing, this core keeps engine temperatures within safe limits. Drivers will notice consistent gauge readings and a more responsive engine under load.
Precision TIG Welding Ensures Leak Free Integrity
Every tube joint and tank seam is crafted using TIG welding, a process known for delivering clean fusion with minimal material distortion. This method produces a dense weld bead that resists crack formation under the fluctuating pressures common in performance cooling systems. By maintaining alignment of internal pathways, it also prevents flow restrictions that can lead to hot spots. All welds are closely inspected in the USA to meet strict quality standards and to ensure dependable service life.
Factory Fit Drop In Installation for GMT400 Chassis
This radiator mounts directly into the original frame rails of 1988 to 1995 C1500, K1500, Tahoe, Suburban and Yukon models without any modification. Inlet and outlet positions align with stock hose locations so builders can reuse existing hardware and maintain a tidy engine bay. The drop in design eliminates the need for bracket fabrication or shims, reducing install time and complexity. Preserving the factory mounting scheme also helps retain chassis strength and vehicle balance during towing or spirited driving.
Choice of Bare Aluminum or Black Epoxy Coating Balances Protection and Conductivity
Select the raw aluminum finish for its natural oxide layer, lightweight nature, and efficient heat transfer. Alternatively, the black epoxy coating creates a durable barrier against road salt, dirt and moisture without hindering thermal conductivity. Each finish is applied to ensure even thickness across tanks and tubes, so heat rejection remains uniform. The epoxy variation also resists staining from engine bay chemicals, keeping the installation looking clean over time. Either option extends service intervals and preserves core integrity in demanding environments.
