Best 30 Inch Scissor Jack for RVs and Trailers

#1 · Best Overall

1. Stromberg Carlson JSC-30

• Load Capacity: 7500 lb
• Material: Alloy Steel
• Compatible with Vehicle Type: Trailer
• Dimensions: 9.63 x 46 x 10 in

Best for: Two-jack travel trailer leveling.

Why it ranks #1: The pair extends to 30 inches and lists 7,500 pounds of support per jack, making it a strong-capacity fit for campers, RVs, and trailers.

Two jacks with 30-inch extension give the Stromberg Carlson JSC-30 a ready-made pair for stabilizing a travel trailer, camper or RV. The listing states 7,500 pounds of capacity per jack, while the included socket and bowtie base support a setup focused on ground contact and adjustment.

The set includes two alloy-steel jacks, so buyers can outfit a pair of stabilizing points from one package. Their 30-inch maximum extension gives room to reach the support position, and the included socket provides an adjustment accessory. The bowtie base is part of the listed design, while the steel construction supports use on campsite or jobsite setups. The supplied details give no retracted height, so storage clearance cannot be gauged from the listed specifications.

Skip it if you need a stated 4-inch retracted height for clearance planning; Camco’s EAZ-Lift listing provides a 30-inch jack set with heavy-duty steel construction.

This pair suits travel-trailer and camper owners who want two 30-inch stabilizers and an included socket. Because no retracted height is supplied, it is less informative for buyers planning around underbody clearance.

#2 · Best Tool-Included Pair

2. Kohree 30-Inch Stabilizer Jacks

• Load Capacity: 6500 lb
• Material: Alloy Steel
• Compatible with Vehicle Type: Camper, RV, Trailer
• Dimensions: 31.5 x 7.3 x 4 in

Best for: Large RV two-jack setup.

Why it ranks #2: This two-jack set reaches 30 inches and includes both a crank handle and drill socket; its listed load capacity is 6,500 pounds.

A 30-inch maximum extension paired with a 6,500-pound load capacity gives this two-jack Kohree set room to stabilize larger RVs and trailers. Its 4-inch retracted height also keeps the jacks compact beneath a parked vehicle, while the included crank handle and drill socket offer two operating options.

The alloy-steel construction has an electrophoresis surface treatment, a practical pairing for a component exposed beneath an RV. Each jack retracts to 4 inches and extends to 30 inches, covering a broad adjustment range while keeping its stored profile low. The package includes two jacks, a crank handle and a drill socket, so buyers can choose hand operation or use a compatible power drill. The stated vehicle fit includes campers, RVs and trailers.

Skip it if you need more than 6,500 pounds of stated capacity per jack; Pafessa’s 7,800-pound USA model lists a higher capacity.

This two-piece set suits RV owners who want a 30-inch reach and both manual and drill-socket operation. Its 6,500-pound capacity and 4-inch retracted height are the key limits to weigh against your setup.

#3 · Best Single-Jack Capacity

3. Pafessa 30-Inch Stabilizer

• Load Capacity: 7600 lb
• Material: Alloy Steel
• Compatible with Vehicle Type: RV
• Dimensions: 33.23 x 7.28 x 4.29 in

Best for: High-capacity single replacement.

Why it ranks #3: The single jack extends to 30 inches and lists a 7,600-pound load capacity in specifications, with a manual crank handle included.

A stated 7,600-pound load capacity gives this single Pafessa stabilizer a high-capacity role for RV and trailer owners replacing one damaged or worn jack. Its 30-inch extension provides adjustment room, while the 4.25-inch retracted height helps limit the space it occupies beneath the vehicle.

The powder-coated, high-grade steel construction is specified to resist rust, which matters for a jack carried beneath an RV. Double-threaded rods support quicker extension and retraction, helping streamline setup and stowing with the included manual crank handle. At 30 inches extended and 4.25 inches retracted, it offers a substantial adjustment range. The listing describes a one-jack package, so buyers assembling a pair should account for needing another unit.

Skip it if you need a matched pair in one package; Camco’s EAZ-Lift set includes two 30-inch stabilizers.

This is a fit for an RV owner replacing a single stabilizer who values a 30-inch range and double-threaded operation. Check that one jack and its listed capacity match the repair or setup you have in mind.

#4 · Best Mounting Plate

4. Pafessa USA 30-Inch Jack

• Load Capacity: 7800 lb
• Material: Alloy Steel
• Compatible with Vehicle Type: RV, Trailer
• Dimensions: 34 x 5 x 8 in

Best for: Existing-hole RV installation.

Why it ranks #4: Its 3.5-by-7-inch universal mounting plate can align with existing holes, and the listing specifies a 7,800-pound capacity and two-year warranty.

A 3.5-by-7-inch universal mounting plate lets this Pafessa jack align with existing installation holes, making it a practical replacement candidate for an RV frame. Its 30-inch format and 7,800-pound listed capacity add substantial stabilization range and support to that mounting-focused setup.

The mounting plate can use existing holes or be welded to the RV frame; bolts are not included, so a bolt-on installation requires sourcing them separately. Powder-coated, high-grade steel is specified for rust resistance, while double-threaded rods support smooth, efficient adjustment during setup. The 7,800-pound capacity and compatibility with RVs and trailers suit a range of applications. As a one-jack package, it is most straightforward when replacing an individual stabilizer.

Skip it if you want hardware included for bolt-on mounting; BAL’s 24003D lists mounting hardware in its package.

Choose this single jack when an existing-hole mounting plate is useful or frame welding is part of your installation plan. It suits buyers seeking a 30-inch RV or trailer stabilizer, provided they arrange any needed bolts.

5. GarveeTech 30-Inch Stabilizer

• Load Capacity: 7500 lb
• Material: Alloy Steel
• Compatible with Vehicle Type: RV

Best for: Compact 30-inch trailer stabilizing.

Why it ranks #5: It combines a 30-inch maximum height with a listed 7,500-pound capacity and powder-coated, high-grade steel construction.

A 4-inch retracted height alongside a 30-inch maximum extension gives the GarveeTech jack a broad adjustment range without a tall stowed profile. Its 7,500-pound capacity is listed for trailer stabilization, making it a candidate for owners prioritizing reach and a compact retracted dimension.

The high-grade steel body has a protective powder coating specified to resist rust and wear, a relevant feature for hardware carried under an RV. Its 4-inch retracted height and 30-inch extension support a wide height range while limiting clearance needed when stowed. The listed 7,500-pound capacity provides a defined stabilization limit. The supplied information identifies the jack as compatible with RVs and says it comes with housing, but does not list a crank handle or mounting hardware.

Skip it if you need a crank handle included; Kohree’s two-jack set lists a handle and drill socket in the package.

This jack fits RV owners who want a 30-inch reach and a low 4-inch retracted height. Verify that its listed package contents and 7,500-pound capacity suit your installation and stabilization needs.

A two-jack set with 30-inch adjustment gives the Camco EAZ-Lift a practical fit for campers, pop-ups and trailers needing stabilization at multiple points. Each jack carries a stated 5,000-pound capacity, and heavy-duty steel construction supports use with large recreational vehicles.

The pair format means buyers receive two stabilizers, and the 30-inch adjustable height offers room to position them for a parked vehicle. Camco lists compatibility with recreational vehicles and describes the jacks as suitable for pop-ups, trailers and other large vehicles. Heavy-duty steel construction provides the structural material, while the supplied product description also identifies a powder-coated finish for rust protection. The 5,000-pound capacity applies to each jack, defining the stated limit for planning use.

Skip it if you require a higher stated capacity per jack; Pafessa’s USA 30-inch jack lists 7,800 pounds.

This set suits owners of pop-ups, trailers or RVs who want two adjustable steel stabilizers. Its 5,000-pound-per-jack limit is an important boundary when matching the jacks to your setup.

Included mounting hardware distinguishes the BAL 24003D for RV owners installing a 30-inch leveling jack without sourcing that hardware separately. Its 4-to-30-inch extension range and 5,000-pound static load rating combine adjustment room with a clearly stated stabilization limit.

#8

8. RecPro 30-Inch Scissor Jacks

• Load Capacity: 5000 lb
• Material: steel
• Compatible with Vehicle Type: Trailer

Best for: Two-pack with handle included.

Why it ranks #8: This two-pack lists 5,000 pounds, offers a 30-inch height option, and includes a crank handle and bow-tie bases.

A two-pack with a crank handle included makes the RecPro set a straightforward starting point for outfitting two trailer support points. These 30-inch jacks retract to 4 inches, and their bow-tie bases are specified to help stabilize the RV when positioned.

The listed 5,000-pound capacity and 30-inch height option establish the set’s stated support and reach, while the 4-inch retracted height helps with clearance planning beneath a parked trailer. A rust-resistant powder coating addresses exposure during storage and use. RecPro specifies a 3/8-inch mounting-plate bolt-hole size, useful when planning installation hardware, and includes a crank handle. The bow-tie bases are intended to support stable contact; the supplied details do not identify included mounting bolts.

Skip it if you need a higher stated capacity per jack; Pafessa’s USA 30-inch jack lists 7,800 pounds.

This pair suits trailer owners seeking 30-inch reach, a compact 4-inch retracted height and a supplied crank handle. Check the 3/8-inch mounting-hole specification and 5,000-pound capacity against your installation.

#9

9. Cynder 00673 Leveling Jack

• Load Capacity: 5000 lb
• Material: Steel
• Compatible with Vehicle Type: Trailer
• Dimensions: 32.5 x 3.9 x 7.2 in

Best for: Wide-footprint RV stabilizer.

Why it ranks #9: This 30-inch, 5,000-pound single jack can bolt or weld onto a vehicle and has large 4.5-by-9-inch footpads.

A 4.5-by-9-inch footpad gives the Cynder 00673 a broad ground-contact area, specified to combat sinking and tilting. Its 4-to-30-inch extension range also avoids reliance on cumbersome wood blocks, making it a useful option for RV owners needing adjustable support.

The large footpads work alongside the steel construction to provide a wider contact area under travel trailers, fifth wheels and motorhomes. A 30-inch maximum extension and 4-inch minimum height define the adjustment range, while the listing says this avoids the need for cumbersome wood blocks. Bolt-on or weld-on installation gives two frame-mounting approaches, and powder coating is specified for rust protection. The jack is sold as a single unit with a 5,000-pound capacity.

Skip it if you need two jacks together; Stromberg Carlson’s JSC-30 is listed as a two-jack set.

This single stabilizer suits RV owners who value a large footpad and a 30-inch adjustment range. Its 5,000-pound capacity and one-jack package should guide fit and quantity decisions.

#10

10. Cobra-Tek 30-Inch Scissor Jack

• Load Capacity: 5000 lb
• Material: Alloy Steel
• Compatible with Vehicle Type: Trailer
• Dimensions: 8 x 32 x 5 in

Best for: Bolt-on or weld-on replacement.

Why it ranks #10: It fits the 30-inch trailer-stabilizer use case and lists a 5,000-pound capacity, but its 30-day limited warranty is shorter than several alternatives.

Bolt-on or weld-on frame installation gives the Cobra-Tek jack flexibility for a trailer owner choosing between fasteners and welding. Its 30-inch maximum height and worm-gear mechanism pair adjustment range with a feature specified to help prevent slipping during operation.

The alloy-steel jack has a stated 5,000-pound load capacity and is listed for trailer use. Its frame can be secured by bolt-on or weld-on installation, allowing the mounting approach to match the work planned for the vehicle. A worm-gear mechanism is specified to prevent slipping, supporting controlled operation, while the 30-inch maximum height provides adjustment reach. This is a one-jack package, so buyers equipping multiple support points need to plan for additional units.

Skip it if you need a pair in one package; RecPro lists a two-pack with a handle included.

This single jack suits trailer owners who want a choice of bolt-on or weld-on mounting and a worm-gear mechanism. Consider the one-unit package and 5,000-pound capacity when planning a complete setup.
