Toyota Research and Development has chosen to partner with Tru-Line Laser Alignment to take care of their at-port wheel alignment. Tru-Line’s portability, flexibility, and ability to handle a wide variety of vehicle types caught Toyota’s attention. Zach Zwillinger of Toyota Research and Development calls Tru-Line’s wheel alignment system, “a straight-forward process that makes vehicle suspension alignment simple and effective.” For 30 years Tru-Line has been producing the most portable, reliable, and easy-to-use laser wheel alignment system on the market. Tru-Line believes in quality and in filling the customer needs regardless of vehicle type or working environment. Tru-Line included RaceRamp’s lightweight portable ramps as part of its solution for Toyota Research and Development, with winning results for all parties.
Car and Driver – Track Day Accessories
Track Home: These items bring the comfort of your crib—and garage—to the circuit From the October Issue of Car and Driver: Car and Driver Gearbox October 2011 A good track day will take you out of your comfort zone, but that can also mean going without certain conveniences. Spend a little money, and the products featured here can ease track days’ discomforts—if not, alas, their humiliations. Tru-Line TL-12 Portable Laser-Alignment System Lasers! The Tru-Line alignment system makes possible those last-minute chassis adjustments. It’s portable and works on uneven surfaces, allowing you to measure and then mess with toe, camber, caster, and steering-axis inclination. The measurements are easy to read, but make sure you have a shop manual on hand in order to properly affect adjustments. Problem: It’s harder to blame the car when you can adjust it on-site. Did we mention the lasers? ($5995) Race & Stock Car Laser Wheel Alignment


I was looking for a wheel alignment system that could handle almost any vehicle I was asked to build, from Battle Wagons to Fast and Furious jump cars to 3 axle police cars. What I found is Tru-Line could handle the wheel alignment, but could also be used in building chassis and frames.

The computer wheel alignment systems do not have the flexibility or portability we needed, we can afford any system we want and we choose Tru-Line.
