American tuner Hennessey has released a supercharger kit for the 2015 Cadillac Escalade.

The HPE550 upgrade is offered for the Escalade's V8 6.2-liter engine and will bump output from the standard 420 bhp (313 kW) and 460 lb-ft (623 Nm) to 557 bhp (415 kW) and 542 lb-ft (734 Nm) of torque. The kit will set you back 15,950 USD and will include an air-to-water intercooler system and a remapped engine ECU.

For an additional 6,950 USD clients can opt for the tuner's H10 20-inch forged monoblock wheels compatible with the Escalade's factory tires. Hennessey says these wheels have a lower rotating-mass which allows more power to reach the tires.

This HPE550 package is also compatible with various other models such as the 2014/2015 Chevrolet Silverado, 2014-2015 GMC Sierra and the 2015 GMC Yukon Denali. It comes bundled with a three-year / 36,000-mile engine warranty.
