SIMPSON OFF-ROAD ENGINEERING

Australian Made Turbocharging and Off-Road Accessories

Established in the Southern Highlands of NSW, Simpson Off-Road Engineering was founded to service a need for cost effective solutions to turbocharge the legendary naturally aspirated 1HZ Toyota engine. 1HZ engines power over one million Toyota Landcruisers and Coaster buses across the globe and are still being produced today - a reliable and capable engine that benefits greatly from turbocharging.

At Simpson Off-Road Engineering, we love anything off-road - including Enduro/Hard Enduro dirt bike riding and racing. We are expanding a line of quality parts aimed to help all riders - from National level racers, to weekend trail riders.

Proudly Australian.
