Heavy Commercial Wheel Alignment With Four Post Lift With Accessories

Wheel alignment on a four-post car lift (alignment rack) is the process of adjusting a vehicle’s suspension geometry—camber, caster, and toe—while the car rests on its wheels on a level, elevated platform. Unlike a two-post lift (where wheels hang free), a four-post alignment lift supports the vehicle by its tires, simulating normal driving conditions for accurate measurement and adjustment. How It Works Drive-On Setup The vehicle is driven onto the four-post lift’s runways and secured. Level & Lock The lift raises the car to working height and locks into position to ensure stability. Turntables & Slip Plates Front turntables allow wheels to pivot freely during caster and toe adjustments. Rear slip plates allow slight lateral movement so suspension settles naturally.
