Truck Optical 2 Wheel Laser Alignment Gauges
These Gauges probably cost less than the set of tyres shredding away on your Truck right now due to misalignment... They certainly cost less than repeated sets of shredded tyres...
It's an absolute no-brainer. These gauges will save you thousands in tyre and fuel costs. That's a fact. Non arguable. These gauges are not an investment, they are a bank balance upping tool.
They're easy to use, robust, accurate and portable.
