Do these ramps need any assembly or prep before first use?

They're ready to use straight out of the box—no assembly required. Just place them on level ground and drive up.

Can I use just one ramp, or do I need both?

Use both ramps together for balanced support. One ramp alone won't safely support your vehicle during work.

Will these work on an uneven driveway?

Service ramps work best on level, solid ground. If your surface slopes or is soft, find a flat spot to set them up for safety.
