Over thousands of heat-expansion cycles, vibration, and elevated coolant pressures, these OEM crimp joints lose sealing tension, resulting in hairline fissures at the tank-to-core seam and near the transmission oil cooler fittings. Additionally, high ambient temperatures combined with the restricted frontal airflow of the SSR retro-styled fascia cause severe heat soak during stop-and-go driving or aggressive throttle usage, quickly overwhelming the slim, single-row factory core volume.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement radiator features a high-density 3-row brazed tube-and-fin aluminum core engineered for maximum conductive surface area and fluid dwell time. The end tanks are precision cut from high-grade sheet aluminum and 100% TIG-welded to the core plates, completely doing away with fail-prone elastomeric seals and crimped plastic. With expanded coolant capacity and superior thermal heat rejection, it mitigates boiling risks under sustained loads while maintaining factory mounting points and hose routing geometry.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2003-2006 Chevrolet SSR\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e5.3L LM4, 6.0L LS2 \/ GMT368\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e300-400 hp \/ 331-400 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eDPI 2714 \/ OEM 21996495\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2003 Chevrolet SSR Base 5.3L V8 LM4\u003c\/li\u003e\n  \u003cli\u003e2004 Chevrolet SSR Base 5.3L V8 LM4\u003c\/li\u003e\n  \u003cli\u003e2005 Chevrolet SSR Base 6.0L V8 LS2\u003c\/li\u003e\n  \u003cli\u003e2006 Chevrolet SSR Base 6.0L V8 LS2\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Chevrolet Muscle Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to withstand the aggressive heat loads of Gen III and Gen IV V8 engines, this unit restores cooling margin to ensure reliable power delivery down the quarter-mile or on open highways.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50496505577720,"sku":"DS-E9OWVYSWL","price":209.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/aluminum-radiator-for-chevrolet-ssr-2003-2006-5-3l-6-0l-1.jpg?v=1789245329","url":"https:\/\/performancechiptuning.com\/products\/aluminum-radiator-for-chevrolet-ssr-2003-2006-5-3l-6-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
