LS Radiator for 1973-1977 A-Body Vehicles with Automatic Transmission
Completing an LS swap in a tight 1973 to 1977 A-Body engine bay demands a radiator that matches original mount locations and hose routing. Built for chassis including Chevy Chevelle, Monte Carlo, El Camino, Laguna, GMC Sprint, Buick Regal, Oldsmobile Cutlass, Pontiac Grand Am and Grand Prix with an LS engine and automatic transmission, this radiator features a core and tanks made from high quality aluminum with 100 percent TIG welded construction for leak free service. Offered in natural bare finish or a protective black epoxy coating, it ships without fans to preserve factory spacing for custom cooling fans. Secured by stock brackets and hose ports, it delivers a direct bolt in fit without modification.
Precision Fit for 1973 to 1977 A Body LS Conversions
This radiator is engineered specifically for 1973 to 1977 A body applications equipped with an LS engine and automatic transmission. By focusing on this exact model range, we guarantee compatibility with factory frame rails and crossmember locations. The design works in concert with MuscleRods mounts to maintain proper engine placement and preserve ideal drivetrain angles. That precise alignment reduces stress on your torque converter and output shaft while ensuring consistent fluid flow under load. Direct matching of upper and lower hose outlets means no modifications or adapter fittings are required when replacing the original unit or upgrading your cooling system.
Robust All Aluminum Construction
Built from 100 percent TIG welded high quality aluminum tanks and core, this radiator delivers efficient heat transfer and long service life. Every weld is inspected to meet rigorous quality standards, creating a leak free seal across all seams. The full aluminum assembly sheds weight compared to factory copper units while resisting corrosion in harsh operating environments. Made in the USA, each core is pressure tested to validate structural integrity under both static and thermal cycles. The result is a radiator that excels in daily driving, spirited street runs, or track use without compromise.
Seamless Integration and Installation
Installation is straightforward thanks to exact OE style mounting tabs and inlet locations that match 1973 to 1977 service points. The radiator's filler neck aligns with the factory shroud opening for simple top mounting, and preformed lower fittings accept standard hose sizes used in LS swap kits. Integration with MuscleRods brackets ensures that the radiator sits square to the engine, maintaining consistent coolant flow and preventing vibration fatigue. No trimming or special shims are needed, reducing installation time and delivering a professional fit straight from the box.
Trust MuscleRods to deliver a durable all aluminum radiator that requires no alterations. To complete your cooling upgrade, consider our 1973-1977 A-Body LS Radiator (Automatic Transmission) with Fans, the same radiator but with fans.
