REMEMBER the sand-scorching, orange, LS3-powered Holden Colorado from the May 2017 issue of 4X4 Australia? Of course you do, it was one of the most popular stories we ran last year.
Since that initial vehicle, the company behind it, Queensland’s Killa Kustom Kables & Conversions, has built a few more of them including current model Colorados and an LSA version it calls the Killarado.
Like everything Harrop does, the Superado takes the original product and bumps it up to the next level. They crank all the dials up to 11 and do it with an OE attention to detail, engineering and reliability. The Superado doesn’t stop with just the V8 engine swap, but it includes a matched suspension package, uprated wheels, tyre and brakes, and a host of other options.
Harrop is, in fact, offering two tailored versions of the Superado. The white car you see here rides on 18-inch Method Race Wheels wearing Toyo’s excellent Open Country R/T tyres,and it has an off-road-tuned suspension package.
While the black Z71 car sports 20-inch Methods and lower-profile Toyo AT2s for a more urban look and improved on-road characteristics. It also has the factory supercharged LSA engine.

Both on- and off-road variants have a Harrop suspension package featuring remote reservoir dampeners from Victorian suspension specialists, Shockworks. These are then tailored to the vehicle be it for the street or more off-road usage.
There’s a big brake package offered that includes Harrop six-piston front callipers and massive 355mm rotors, to deliver a firmer pedal feel and superior braking performance than Holden ever could. These also fit behind the specific Method wheels but will not go behind factory Holden 18-inch alloys.
Engine choices are the GM 6.2-litre LS3 – either naturally aspirated or equipped with a Harrop TVS2650 supercharger kit – or the factory supercharged LSA 6.2L. Only the 6L80 six-speed auto is offered, and the four-wheel drive system remains GM’s part-time set up including low range. Add in a set of Harrop E-lockers, for the ultimate off-road weapon.
Styling options for the Superado include barwork, lights, roof racks, bonnet scoop, decals and a bespoke leather interior, so you can tailor the vehicle to whatever your tastes. Go wild and extreme or keep it a sleeper that only reveals its identity when the throttle is mashed.
What’s all this performance cost? That depends on what options you check, but rest assured the Harrop packages are tried and tested to be as good as or better than the factory in terms of reliability, something few engineering firms can offer. And no OE factory offering can deliver the feel and performance of the full Superado conversion.
