Corvette C7 ZR1 Upgrades & Modifications

Chevrolet’s C7 Corvette ZR1 production may be over, but the aftermarket performance upgrades are still strong! Hennessey® Performance is proud to offer reliable, blistering performance upgrade and modification packages for this LT5-platformed machine.

Hennessey Performance offers only the highest-quality builds, and we are recognized for having the best warranty in the industry. Our strict quality control and high assessment standards help us deliver the best possible product. In addition, to protect owners, their investments, and their vehicles, we have stringent requirements and standards for vehicles we accept for upgrades. 
 
When vehicles get older and accumulate miles, components age, and wear – understandably, the risk factor of modifying them increases. As a result, Hennessey Performance does not offer a warranty on vehicles older than three years, regardless of condition or maintenance, or vehicles with more than 20,000 miles. 
 
If you have questions on whether your vehicle meets our standards for accepted builds or would like further clarification, please contact us at 1.979.885.1300.
