Buying Guide: Key Purchase Considerations

- Lift height range: Consider both the minimum lifting height and maximum height, especially for low-clearance vehicles or taller four-post launches.
- Compatibility: Verify compatibility with your specific four-post lift model, including the need for adapters or accessory pads.
- Pad design and adjustability: Adjustable screw pads and interchangeable adapters broaden supported vehicle profiles and improve contact reliability.
- Mobility and storage: Look for models with caster-ready bases or compact footprints if space is limited in your shop.
- Reliability and warranty: Favor brands with solid warranties and known reliability to minimize downtime and service costs.
- Maintenance needs: Consider ease of lubrication and inspecting contact surfaces to ensure long-term performance.
- Operational safety: Check for stability features, locking mechanisms, and manual overrides where applicable.
