Description
The LS9 engine is the supercharged 6.2L V8 that powered the 2009–2013 Chevrolet Corvette ZR1, and it remains one of the most capable factory performance engines General Motors has produced. A used LS9 engine gives ZR1 owners and performance builders access to genuine GM hardware as an alternative to a new crate motor.
What Is the GM LS9 Engine?
The LS9 is a Gen IV small-block V8 that GM certified at 638 horsepower and 604 lb-ft of torque. It combines an aluminum block, forged internals, titanium connecting rods, a four-lobe Roots-type supercharger with an integrated charge cooler, and a dry-sump oiling system. GM technicians hand-assembled each engine at the Performance Build Center in Wixom, Michigan.
Common Uses: Replacement and Performance Builds
Most buyers choose a used LS9 engine to replace a damaged or worn engine in a C6 Corvette ZR1. Others use it for restomods, custom swaps, and track builds where a factory-supercharged LS-family V8 is the goal. Swaps into other vehicles take extra planning, because the dry-sump system calls for an external oil reservoir and supporting plumbing.
How to Identify the Correct Replacement
Start with your vehicle’s year, model, and VIN, then compare them with the engine listed on this page. Confirm that the engine is a true LS9 and not the naturally aspirated LS3 or the supercharged LSA, which are different engines even though they share 6.2L displacement. If you are unsure, contact our team with your VIN and questions before you order.
Compatibility Considerations
The documented factory application is the 2009–2013 Corvette ZR1. Fitment in any other vehicle depends on the transmission, engine management, wiring, cooling, and oil system. The LS9 uses a nine-bolt crankshaft flange, so some transmission pairings may need an adapter. Also confirm which accessories and components come with the specific engine you are buying, since configurations can vary.

Frequently Asked Questions
What is the LS9 engine used for?
The LS9 is a supercharged 6.2L V8 built by General Motors for the 2009–2013 Chevrolet Corvette ZR1. Today it is used to replace ZR1 engines and to power custom, restomod, and track builds.
Which vehicles use the LS9 engine?
The factory application is the 2009–2013 Corvette ZR1. GM Authority also lists two low-volume vehicles, the HSV GTSR W1 and the Equus Bass 770. Confirm any other fitment with your VIN before buying.
How do I identify the correct replacement?
Match your year, model, and VIN to the engine on the listing. Verify it is an LS9 rather than an LS3 or LSA, since all three are 6.2L V8s. Contact us if you need help comparing engine details.
Can I swap an LS9 into a different vehicle?
It is possible, but plan for the dry-sump oiling system, which needs an external oil reservoir. Also plan for the integrated supercharger and charge-cooler cooling circuit, compatible engine management and wiring, and a nine-bolt crankshaft flange that may need a transmission adapter.
What should I check before purchasing?
Confirm your VIN, transmission pairing, and the components included with the listed engine. The LS9 requires premium fuel. Ask about any details specific to this unit, because general LS9 information does not describe an individual engine’s history.
