appropriate capacity (not included) under the
proper lifting point referred to in the vehicle owner’s
manual. Always use two jack stands, position them
at the same point on each side of the vehicle.
WARNING! The rated capacity of jack stands is per pair,
not the individual capacities combined unless specically
noted on the product by the jack stand manufacturer. Do
not exceed rated jack stand capacity. Ensure that the
vehicle support points are fully captured between the outer
lugs of both jack stands. Use a matched pair of jack stands
per vehicle to support one end only. Use 1 pair per vehicle
