Kohree 4-PCS Flat Top Slide Out Supports
Maximizes stability for heavy slide-outs with a flat top that eliminates the need for wood blocks. The top blocks are designed for a strong, uniform contact surface. Height adjusts from 20″ to 49″ via a power drill or a hand crank. Each kit supports up to 5,000 lbs per jack and up to 20,000 lbs total when using all four jacks. Best for full-time RVers or large fifth wheels that require even distribution and minimal bounce. A potential limitation is the need for a power drill or crank for quick adjustment; manual operation remains possible but slightly slower.
Kohree Set of 2 RV Slide Out Supports
This 2-pack provides quick, tool-assisted height adjustment from 20″ to 49″ with a power drill or hand crank. Each jack handles 5,000 lbs, offering solid support for mid-sized trailers or heavier sections of a single-axle setup. Best for users who want a balanced, cost-efficient pair and a straightforward upgrade path from single-jack solutions. Note that the 2-pack may require additional jacks for larger or taller rigs to achieve full stabilizer symmetry.
Kohree RV Slide Out Support Jacks With Flat Top (4PCS)
This 4-piece kit emphasizes an upgraded flat-top design for stable, uniform contact with the slide-out frame. Capable of supporting up to 20,000 lbs in total across all four jacks, it is well-suited for large RVs, including Class A and heavy fifth wheels. The setup remains fast via a socket-driven lift, with a hand crank as a backup. Choose this if your rig benefits from four-point stability and maximum load distribution. Avoid if you only need a paired setup for a small trailer.
VEVOR RV Slide Out Support Jacks (2-Pack)
Two jacks provide sturdy stability with 5,000 lbs per jack and a 20-48″ height range. This kit is versatile for many RV types and ground conditions, and the folding handle makes adjustments straightforward. It’s a practical choice for users who want reliable, middle-ground capacity with flexible height adjustment. Caution: on very soft or uneven ground, additional leveling blocks are recommended to prevent sinking or wobble.
Garvee RV Slide Out Support Jacks (Set of 4)
A four-jack setup offering up to 5,000 lbs per jack for a total of 20,000 lbs. Height range from 21.1″ to 49″ provides broad compatibility with various RV models. Includes a crank handle and a magnetic socket for drill-assisted lifting. Best for full-size travel trailers and motorhomes needing comprehensive stabilization. A limitation is that four jacks require more storage space and setup time compared to two-jack kits.
Buying Guide: Key Considerations for Choosing RV Slide Out Jacks
- Weight capacity: Match the total load of your slide-out and trailer. For large fifth wheels, aim for higher total capacity and multiple jacks to distribute weight evenly.
- Height range: Ensure the 20″–49″ (or 20″–48″) span fits your ground clearance and the retracted height of your RV’s slide-out mechanism.
- Top design: Flat-top blocks improve contact with the slide-out frame and reduce the need for wood shims, which can simplify setup and increase stability.
- Operation method: Drill-powered and hand-crank options provide flexibility. Drills speed up setup, but backups are useful in power outages or if a battery is low.
- Number of jacks: Two-jack kits are compact and cost-effective; four-jack kits deliver greater stability for large or heavy slide-outs.
- Materials and durability: Look for sturdy steel construction with corrosion-resistant finishes to withstand outdoor conditions and seasonal storage.
- Ground surface considerations: On soft ground, use leveling blocks to prevent sinking and ensure a level trailer.
- Ease of storage: Consider whether your RV has space to store the jacks and any included accessories like sockets, cranks, or extra hardware.
