Mustang GT350 Upgrades & Modifications

Mustang’s GT350 Upgrades by Hennessey® Performance are warranty-guaranteed! Our HPE performance upgrades and modifications package ramp up the power to 850HP.

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.
