Jack stands are safety devices used to securely support a vehicle after it has been lifted with a jack. They prevent accidental drops and ensure a stable, safe working environment during maintenance tasks like oil changes, brake inspections, or tire rotations. Always use two or more jack stands rated for your vehicle’s weight and place them on solid, level ground. Never rely solely on a hydraulic jack for support. Look for stands with wide bases and locking pins for added security. Proper use of jack stands is critical to personal safety and should never be skipped. Investing in high-quality stands is a small price to pay for peace of mind during every repair.
