Show original supplier description
The 1988-1993 LS Radiator is a custom-fit cooling solution engineered specifically for LS and LT engine conversions in 1988-1993 Chevy C1500, K1500, and Suburban GMT400 OBS chassis vehicles equipped with manual transmissions. This full-width, 34-inch core aluminum radiator is designed to drop directly into the original factory mounts without requiring any modifications or custom bracket fabrication. Its construction features high-grade aluminum tanks and core, with all joints 100% TIG-welded for maximum strength, leak resistance, and durability through thermal cycles. The radiator is available in either a classic bare aluminum finish or a stylish black epoxy coat for enhanced corrosion protection. Each unit is manufactured in the USA and undergoes rigorous quality control, including pressure and helium leak testing, to ensure reliable performance. The precise fitment and mirror-like inlet/outlet port positions ensure straightforward hose routing, keeping lines clear of engine bay components. Key features include its 34-inch full-width aluminum core, 100% TIG-welded construction, and USA manufacturing. The benefits derived from this design include rapid heat shedding to keep LS/LT manual transmission swaps stable, superior thermal efficiency, light-weight construction, corrosion resistance, and fast heat rejection for long-term performance and reliability.
