Proudly designed and manufactured in Australia, Harrop offer
a range of packages engineered specifically to unleash the Holden
Commodore range. We have revised our Performance Package offerings with a
wide range of options to suit every budget and power requirement. We start with
our entry level Stage 1 Package including an OTR and ECU recalibration and go
right through to the impressive Stage 5 package, which produces a massive 490
kW's at the flywheel with our Harrop TVS2300 supercharger.
