Description
The Corvette ZR1 engine represents Chevrolet’s ultimate performance engineering. In the C6 ZR1 (2009–2013), the LS9 6.2L supercharged V8 delivered 638 hp with forged internals and advanced cooling systems. Later, the C7 ZR1 (2019) featured the LT5 6.2L supercharged V8, producing 755 hp with upgraded supercharging, intercooling, and airflow improvements.
These engines are exclusive to the ZR1 but are also highly prized for custom builds. Known for reliability under extreme performance, both the LS9 and LT5 stand as milestones in Corvette history
ZR1 engine fitment is completely generation-specific. The C6 ZR1 LS9 and the C7 ZR1 LT5 share no major components. Both use generation-specific oil pans, supercharger assemblies, and engine management systems. Our application review confirms the exact ZR1 engine generation for your specific vehicle before it ships.
When evaluating a used engine versus a remanufactured engine or an OEM engine for a Corvette ZR1, the performance stakes are the highest in the Corvette lineup. A used Corvette ZR1 engine from a verified low-mileage donor is the only path to restoring the factory-specification supercharged output with original supercharger, original titanium components, and original hand-assembly provenance. As a used OEM engine, it preserves what no remanufactured engine from reconditioned parts can replicate: the complete factory ZR1 assembly as GM built it.
Every used Corvette ZR1 engine ships with up to a 90-day warranty and arrives within 2 to 5 business days. Installation is not included. ZR1-specialist installation is strongly recommended. These are genuine GM OEM engines, and we stand behind every unit.
