Buying Guide: Key Considerations For RV Leveling Jack Springs
- Jack capacity and stroke: Most RV hydraulic jacks are 6,000 lb or 9,000 lb with a 13″ or 15″ stroke. Confirm your jack rating and stroke to ensure correct spring length and coil count.
- Spring material and corrosion resistance: Look for steel springs with rust resistance for outdoor use. The kits listed here commonly use high-quality steel with good durability ratings implied by material descriptions.
- Number of springs per kit: Some kits come with two springs, others with four. Consider whether you need a full set for all corners or a targeted replacement for a single jack.
- Cylinder assembly compatibility: The ability to match common part numbers (AP0468, AP0498, AP0585, etc.) improves fit across many jacks. Double-check your jack’s cylinder assembly when ordering.
- Installation and replacement intervals: Springs wear per cycle count and environmental exposure. If your system experiences frequent use, a four-spring kit may offer more even wear distribution over time.
- Fit and geometry: Exact measurements (hook-to-hook, base-to-base, diameter, coil count) determine fit. Use the listed dimensions to compare with your existing springs.
Comparative Quick Tips
- Best for broad compatibility: Kits listing many compatible cylinder assemblies and compatible with multiple models.
- Better for full replacement: Four-spring kits provide even balance across corners and longer replacement cycles.
- Choose this if you know your jack model and stroke: Exact-fit kits reduce the risk of misfit and noise during operation.
