This 2021 Dodge Durango SRT Hellcat has been transformed with an
extensive, professionally built stroker engine package. At its core
is an HHP/BES 426 (7.0L) stroker short block built on
Hellcat/Trackhawk/Demon architecture, featuring an 8-counterweight
crankshaft, billet rod upgrade, ARP main studs, and a 9.5:1
compression ratio. It's topped with HHP/BES Stage 2 CNC-ported
cylinder heads, ARP head studs, and Cometic MLX head gaskets, along
with an HHP Racing custom limiter camshaft, a COMP Cams phaser lock
kit, a Mopar timing chain set, and Mopar heavy-duty lifters.
Supporting hardware includes Stainless Works long-tube catted
headers, a JLT cold air intake, Injector Dynamics ID1050x
injectors, an ATI Super Damper harmonic balancer, a Metco Hellcat
upper supercharger pulley, and an upgraded radiator with a
Mishimoto thermostat and heavy-duty serpentine belt. The build was
finished with custom HHP performance tuning (street and dyno), a
Diablosport Trinity T2 tuner, and an HHP PCM unlock, ensuring the
entire package runs exactly as intended.
This is a true built Durango SRT Hellcat with real, documented
performance work behind it rather than bolt-on parts alone - a
serious combination of power and engineering for the enthusiast
buyer.
