2018 Jeep Grand Cherokee Trackhawk Hennessey HPE1000

This 2018 Jeep Grand Cherokee Trackhawk was modified by Hennessey Performance of Sealy, Texas, with their HPE1000 package, and it resided with its original owner until it was purchased in November 2024 by the seller. Work carried out between November 2025 and March 2026 by Prolific Performance of Branford, Connecticut, at a cost of over $36k included rebuilding the Hennessey-supercharged 6.2-liter V8 with a replacement short block, CP-Carillo pistons and connecting rods, and ARP studs. Riding on Eibach lowering springs, the truck has been further modified with a ZPE GripTec upper pulley, a custom camshaft, chromoly pushrods, a Corsa cat-back exhaust system, and an Eibach Pro-Camber kit. Additional details include an eight-speed automatic transmission, an electronic limited-slip rear differential, Quadra-Trac four-wheel drive, and over $11k in options. This Trackhawk has been driven 20k miles and is now offered with a digital window sticker, dynamometer test results, service records, and a clean Connecticut title in the seller’s name.

The Grand Cherokee Trackhawk features a front bumper cover with cooling ducts along with a vented hood and body-color fender extensions. This example is finished in Billet Silver Metallic Clearcoat (PSC) with a Hennessey rear badge, and additional exterior features include bi-xenon headlights with washers as well as a dual-pane panoramic sunroof, a roof spoiler, parking sensors, LED taillights, window tint, and quad exhaust outlets. Some paint chips are noted on the left-side fender. The Carfax report shows damage in April 2026.

The truck rides on Eibach lowering springs, and other revisions to the suspension include an Eibach Pro-Camber kit with billet aluminum adjustable control arms. The black satin-finished 20? aluminum wheels are mounted with 295/45 Pirelli Scorpion Verde All Season tires. Stopping power is provided by yellow-finished six-piston front and four-piston rear Brembo calipers.

The heated and ventilated power-adjustable front seats feature Trackhawk logos on the backrests and are trimmed in Dark Ruby Red Laguna leather, as are the heated rear seats. Carbon-fiber trim adorns the cabin, Hennessey-branded mats line the front footwells, and the Signature Leather Wrapped Interior Package added leather-wrapped lower panels. Further amenities include a 19-speaker Harman Kardon sound system, red seatbelts, remote start, Keyless Enter ‘N Go, dual-zone automatic climate control, and a UConnect 4C infotainment system with an 8.4? touchscreen, navigation, and Apple CarPlay and Android Auto connectivity.

Tags affixed to the ceiling and under the hood identify the vehicle as Hennessey HPE1000 number 10.

The heated leather-wrapped steering wheel is mounted on a power tilting and telescoping column and fronts paddle shifters, a 200-mph speedometer, a central tachometer, and gauges for coolant temperature and fuel level. The driver is aided by a ParkView rearview camera, LaneSense Lane Departure Warning Plus, Parallel and Perpendicular Park Assist, blind-spot monitoring, cross-path detection, and adaptive cruise control. The digital odometer indicates 20k miles, approximately 6k of which were added under current ownership.

The 6.2-liter V8 was initially modified by Hennessey Performance with their HPE1000 package, which added a supercharger system. Following an injector failure, it was built with a Disomma Racing Engines-sourced replacement short block between November 2025 and March 2026 at a cost of over $36k by Prolific Performance of Branford, Connecticut, and it retains its Hennessey supercharger. The work included installing CP-Carillo 9.5:1 pistons, CP-Carillo Bullet Series connecting rods, and ARP main studs along with machining and resurfacing the cylinder heads. Other components fitted then include the following:

ZPE GripTec upper pulley
ARP head studs
Chromoly custom pushrods
Custom camshaft w/phaser lockout plate
Upgraded fuel injectors
ATI harmonic balancer
Mishimoto 180-degree thermostat
Custom engine management from Prolific Performance

The truck also has a JLT Performance air-intake system and oil separator. The results of a dynamometer test are displayed in the gallery below.

Power is sent to all four wheels through a TorqueFlite eight-speed automatic transmission, a Quadra-Trac four-wheel-drive system, and an electronic limited-slip rear differential. The transmission has revised tuning, and the Corsa cat-back exhaust system features custom-fabricated stainless-steel downpipes. The transfer case is said to have been replaced in January 2026, and the transmission fluid and gear oil were replaced in March of that year.

The digital window sticker lists factory colors, equipment, and a total price of $98,565.
