LS/LT Swap Radiator for 1988-1995 Chevy/GMC C/K Series Trucks and SUVs
When you graft an LS or LT V8 into a GMT400 chassis from model years 1988 through 1995 on Chevy C1500 or Suburban trucks with automatic transmission, coolant demands rise sharply under steady towing or spirited highway driving. The 28.25 inch aluminum core excels at pulling heat from the coolant quickly while its precise TIG welded tanks eliminate crack initiation points. Factory inlet and outlet ports align with original positions and fit existing mounts on C1500, K1500, Tahoe, Suburban, and Yukon frames without modifying frame rails or hoses. Finished in bare aluminum or black epoxy, this radiator combines corrosion resistance with reliable thermal performance for hot weather work and spirited runs.
Expansive Aluminum Core for Accelerated Cooling
The 28.25 inch aluminum core delivers an expansive surface area that accelerates heat discharge from the coolant into surrounding air. Dense fin arrays and uniform channel spacing promote even flow and eliminate localized hot spots during towing or spirited highway runs. This uniform cooling action stabilizes engine temperature under load and supports consistent gauge readings. When paired with auxiliary fans or factory units the broad core area maximizes airflow without increasing overall assembly size. Its design is particularly valuable for LS and LT swaps in tight engine compartments.
Precision TIG Welding Ensuring Leak Free Strength
Every seam on the radiator is produced using TIG welding known for precise fusion of aluminum components. This approach achieves clean weld beads that resist crack formation under repeated thermal cycles and engine vibration. By maintaining straight internal passages the weld process avoids flow restrictions that could cause temperature spikes under heavy use. Each unit is handcrafted and inspected in the USA to verify weld consistency and ensure leak free performance throughout seasonal changes and towing demands.
Seamless Drop In Installation with Factory Mounts
Installation is simplified by exact alignment with original mounting points on Chevy C1500 K1500 Tahoe Suburban and GMC Yukon models built from 1988 to 1995. Inlet and outlet ports match factory locations for automatic transmission coolant lines allowing reuse of existing hoses and fittings. This true drop in fit preserves chassis strength and reduces alignment time while delivering a clean under hood appearance. Builders and professional shops benefit from a straightforward fit that avoids custom brackets or frame adaptation.
Aluminum Construction and Protective Finish Choices
Constructed entirely of high quality aluminum the radiator combines low weight with excellent thermal conductivity and natural corrosion resistance. Customers may choose a bare finish that uses the metal's innate oxide layer to protect against moisture while maximizing transfer. The black epoxy alternative adds a resilient barrier against road debris and environmental elements with minimal impact on cooling capacity. Both options feature uniform coating distribution to maintain fin efficiency and support reliable operation under demanding haul or tow scenarios.
