GSL 300 KIT / TOP MOUNT PERFORMANCE KITS
The GSL 300 Kit is what sets our title as Australia's Diesel Kings in stone. With un-beatable results that start at 300kW, you’ll be laughing when you run a quarter mile in under 13 seconds. A colossal engine upgrade, partnered with an Auto Clutch conversion, and a GSL 5 - 4 inch single/twin exhaust, you’ll never need to look for performance upgrades again.
POWER ABOVE THE COMPETITION
GSL are known Australia wide to be the kings of performance, and our turbo kits are exactly why. Beautifully custom welded kits that can bump up power anywhere from 200kW to 300kW+. Being used in some of the most powerful LandCruiser's in Australia, such as Iron Will and Patriot Campers Mega 6x6.
Everything we use is Australia made so you’ll also be supporting local businesses when you buy from us.
