Why This Black Friday Sale Matters
If you’re gearing up for remote outback touring, towing heavy loads, working the paddocks, or keeping your everyday diesel ready for the long haul, it is the perfect time to upgrade the components that matter most.
Fuel Filter Kits
Protect your engine from contaminated fuel. Recommended for every 4WD or work vehicle. Whether you’re exploring Australia’s remote tracks, working the paddocks, on the daily commute, or simply after peace of mind. After all, you never know when you’ll get a bad batch of fuel, and when it happens, the repair bill can be costly. A Fuel Filter Kit is cheap insurance against major damage.
ProVent Catch Can Kits
Keep your intake system clean and your engine breathing freely. ProVent Catch Cans prevent oil and soot build up caused by the EGR process which is a major contributor to power loss, poor efficiency and expensive intake clean outs. If you want long term performance and fewer headaches down the track, a ProVent Kit is protection that is highly recommended for any modern diesel.
Steinbauer Power Modules
More power. More torque. Zero compromise.
Get the power you need without compromising reliability. Steinbauer Power Modules deliver safe, proven gains in power and torque, perfect for towing, hauling, off-road touring or heavy work. They’re engineered for durability, ensuring reliable performance across any terrain.
Fuel Injection Parts
Precision matters. Our injectors, pumps, seals and line kits are tested and calibrated for accuracy, ensuring clean combustion, strong performance and dependable fuel delivery. Because of this, they’re ideal for maintaining your workhorse or upgrading for reliability.
And More…
Glow plugs, fittings and sundries, turbochargers and a wide range of diesel engine components — if it’s available in our online store, it’s on sale.
