- Best for: Heavier RVs or multi-slide configurations needing higher load capacity.
- Why selected: Durable welded design paired with high load capacity and long reach.
- Limitation: Requires careful installation alignment due to its larger dimensions and mounting points.
Stroke Control Kit For Hydraulic Cylinders
This kit includes 0.75″, 1.0″, 1.25″, and 1.5″ thickness options to fit cylinder shafts from 1-1/8″ to 1.5″. It converts stroke length quickly and efficiently. Best for buyers who need flexibility to adjust stroke length on different cylinders or retrofit multiple cylinders within an RV system.
- Best for: Owners with multiple cylinders or varying stroke requirements.
- Why selected: Easy-to-use, adjustable kit allows quick conversions without swapping hardware.
- Limitation: Requires careful measurement to select the correct thickness for your specific rod.
Buying Guide
When choosing a hydraulic cylinder for RV slide-outs, consider fit, capacity, and installation ease. Start by verifying the OEM part numbers and thread sizes (e.g., 3/4″-10). Check bore size and stroke length to match the required extension and force. For multi-slide RVs, ensure the cylinder supports the number of slides and the load you expect. Consider whether you need a direct replacement or an upgraded unit with faster operation or higher PSI ratings. Material quality and mounting compatibility (end mounts, cross-tittings) influence long-term reliability, especially in varying road conditions and climates. If you own a Lippert or Lippert-compatible system, consider the Lippert-specific replacement to minimize fit issues. For broader or heavier-duty needs, models with larger bores or higher working pressures (like the 3″ bore, 2500 PSI or 4100 lb capacity options) may be more suitable. Finally, assess installation complexity and whether a replacement cylinder requires professional installation or can be a DIY swap with common tools.
Frequently Asked Questions
- What should I check before buying a slide-out hydraulic cylinder? Confirm the old cylinder’s measurements, including length, stroke, bore, and thread size. Check mounting hardware compatibility with your RV frame.
- Is a higher PSI cylinder always better for RVs? Not always. Higher PSI helps with heavier loads but requires compatible hoses, fittings, and frame strength. Choose a unit that matches your system’s design and the RV’s weight distribution.
- Are direct-replacement cylinders easier to install? Yes. Direct-bolt replacements minimize modification and reduce risk of misalignment.
- Can I use a standard hydraulic cylinder from a workshop with an RV slide-out? It depends on mounting points, bore size, stroke, and port sizing. RV-specific cylinders are typically a safer fit for slide-outs.
- What maintenance is needed for hydraulic cylinders in RVs? Regularly check seals, inspect mounting points for wear, and ensure hoses are free of leaks. Pressure testing (per vendor instructions) helps verify durability.
- Should I replace multiple cylinders at once? If the RV has multiple slide-outs with similar wear patterns, replacing in parallel can provide balanced operation and reduce the chance of uneven extension.
