LS and LT Swap Radiator for 1988-1995 Chevy/GMC C1500, K1500, Tahoe, Suburban, Yukon
The need for a robust cooling solution in a 1988 to 1995 GMT400 truck fitted with an LS or LT engine becomes clear when stock radiators allow temperatures to rise during towing or in stop and go traffic. The 1988 to 1995 LS Radiator 28.25" Core Width (Auto Trans) with Fans couples a 28.25 inch TIG welded aluminum core and twin electric fans to guarantee uniform airflow across every tube and fin. Constructed from high grade aluminum with 100 percent TIG welds, it delivers a leak-free seal against repeated thermal cycling. Engineered for automatic transmission applications in Chevy C1500, K1500, Tahoe, Suburban and GMC Yukon, this radiator bolts to factory mounts with no modifications or adapter plates.
Unmatched Cooling Capacity
The 1988 to 1995 LS Radiator arrives with a 28.25 inch extra wide core that delivers exceptional heat dissipation for both LS and LT powerplants. This increased surface area allows coolant to shed heat more efficiently under sustained load, preventing temperature spikes during towing, street driving, or high output street performance. The enlarged core width extends residence time for fluid flow, reducing thermal stress on both head gaskets and block surfaces. Dual high performance fans are preinstalled to maintain steady airflow at low vehicle speed, ensuring the engine bay remains within safe operating limits in traffic or on technical courses. Their shroud placement is designed to deliver uniform distribution across the entire core face, minimizing hot spots that can lead to detonation or power loss. By combining a broad cooling matrix with intelligent fan management, this radiator provides an essential upgrade for builds that demand consistent thermal control.
Precision Build Quality
Every unit is crafted from premium grade aluminum with tanks and core tubes welded via TIG for full penetration joins and leak free seams. The corrosion resistant properties of pure aluminum alloy help to extend service life, while the lightweight design reduces front end mass for improved handling balance. High grade materials are sourced domestically, and each radiator is assembled and tested in the USA to guarantee performance under harsh conditions. Fixture alignment is held to tight tolerances, ensuring straight inlet and outlet ports that mate without stress on hoses or adapters. By foregoing composite end caps in favor of metal construction, this radiator stands up to repeated thermal cycles and resists fatigue cracking, making it ideal for repeated track days or daily street duties.
Seamless Integration and Installation
This radiator is engineered specifically for 1988 to 1995 vehicles using LS or LT engines with an automatic transmission. It interfaces directly with MuscleRods mounting brackets to maintain correct engine position and drivetrain angles, preserving factory geometry and minimizing vibration. Preinstalled mounting points align with original frame rails, so installation is straightforward with common hand tools. The dual fan assembly ships fully wired, including relays and fused harness sections, for a clean, plug and play solution that can be tied into any 12 volt system. Included hose adapters match factory cooling lines and allow for quick swap of thermal sensor ports if needed. With this radiator in place, projects regain proper underhood packaging and deliver reliable operation from the first startup through every hard run.
Engineered for leak free performance in LS or LT swaps on 1988 to 1995 GMT400 trucks and made in the USA, this radiator offers reliable cooling. To complete your setup with the same radiator but without fans, consider our 1988-1995 LS Radiator 28.25" Core Width (Automatic Transmission).
