If you’ve ever tried to use a standard floor jack on gravel or dirt, you know it’s a wobbly, frustrating mess. I needed something stable for my truck’s off-road maintenance, and the SUNEX Tools 6602RJ 2 Ton Off-Road Jack with its 28.4-inch lift height looked like the right tool for the job.
This jack is built for truck, SUV, and off-road vehicle owners who work outside a perfect garage. Its hybrid steel/aluminum design aims for strength without being too heavy. The trade-off is that at 63.56 pounds, it’s still a substantial piece of gear to haul around. Let’s see if its clever features make up for the heft.

What Stands Out — Key Features
- High Lift Design: The 28.4-inch lift height is a big improvement. It gave me easy access to the undercarriage of my truck for maintenance without needing to stack blocks.
- Compact & Lightweight Design: For its capacity and lift, it’s more portable than many competitor jacks. The hybrid construction helps, but it’s still 63.56 pounds.
- Full-Length Wrap-Around Skid Plate: This is the star feature for off-road use. The steel plate provides a wide, stable base that didn’t sink into my gravel driveway.
- Dual Pump Pistons for Rapid Rise: The dual pistons work great. You get from the saddle to the load much faster than with a single-piston jack, saving time and effort.
- Locking Adjustable Height Adapter: The 4-position locking extension is super handy. I used it to get the perfect starting height on uneven ground, and the rubber pad adds grip.
- Hybrid Steel/Aluminum Build: This mix gives you the strength of steel where you need it while keeping the overall weight somewhat manageable for a 2-ton jack.
- Versatile Vehicle Compatibility: It’s rated for cars, motorcycles, SUVs, trucks, and even snowmobiles. I found it perfectly suited for my midsize truck.
- Stable Footprint: With dimensions of 26.4 x 11.4 x 7 inches, it has a low, wide stance that inspires confidence when lifting heavy loads off-road.

Pros & Cons — The Honest Take
✅ What I Like
- The 28.4-inch lift height is perfect for trucks and SUVs, giving you real working room underneath.
- The full-length steel skid plate makes it incredibly stable on gravel, sand, and soft dirt.
- Dual pump pistons mean it lifts quickly, so you’re not pumping forever to reach the load.
- The 4-position locking height adapter is a smart feature for fine-tuning your start on uneven ground.
- For a 2-ton jack, its compact design (26.4 x 11.4 x 7 inches) is easier to store and position than bulkier models.
❌ What Could Be Better
- At 63.56 pounds, it’s not light. Moving it in and out of a vehicle or across a yard is a workout.
- The hybrid construction helps, but it’s still a significant investment compared to basic garage jacks.
For me, the pros heavily outweigh the cons if you need a stable lift off pavement. The weight is the main compromise, but you’re getting that stability and high lift in return. It’s a purpose-built tool that does its job very well.
⚖️ How Does It Compare?
When looking at the SUNEX 6602RJ, I think about two main types of buyers: those who want something lighter, and those who need more capacity. That’s why I’m comparing it to a popular aluminum off-road jack and a heavier-duty low-profile option.

🔵 Alternative 1: Strongway Aluminum Off-Road Jack
Best for: Anyone who prioritizes portability and needs to carry their jack long distances.
Key specs: 2-ton capacity, full aluminum body, check listing for exact weight and lift height.
Where it beats the main product: It will almost certainly be much lighter than the SUNEX’s 63.56 pounds.
Where it falls short: An all-aluminum body may not feel as rugged or stable as the SUNEX’s hybrid steel/aluminum build.
- Powerful 5-Ton Lifting Capacity---This 5-ton hydraulic floor jack is...
- Hydraulic Quick Lift Dual Piston Technology---Equipped with an innovative...
- Extra-Long Handle for Maximum Leverage---The extra-length handle of this...
⚪ Alternative 2: Maxority 5-Ton Low-Profile Jack
Best for: Owners of heavy-duty trucks or equipment who need a much higher 5-ton capacity.
Key specs: 5-ton (11,000 lb) capacity, low-profile design, check listing for weight and dimensions.
Where it beats the main product: It more than doubles the lifting capacity for much heavier vehicles.
Where it falls short: It will be heavier and bulkier, and likely lacks the dedicated off-road skid plate of the SUNEX.
If you’re constantly hauling your jack up a trail on foot, the aluminum Strongway is a smart choice despite potential trade-offs in feel. Go for the 5-ton Maxority only if you’re lifting vehicles that truly exceed the SUNEX’s 2-ton limit. For most people with a standard truck or SUV who work off pavement, the SUNEX 6602RJ’s balanced hybrid design and dedicated skid plate are the winning combo.
How It Actually Performs
Stability on Unpaved Surfaces
The full-length wrap-around steel skid plate is the real deal. I tested it on loose gravel and packed dirt, and it didn’t wobble or sink like a standard jack. It provides a wide, flat footprint that makes you feel confident lifting a 2-ton vehicle. This feature alone justifies its “off-road” name and works exactly as advertised.
Lift Height and Speed
The 28.4-inch maximum lift is excellent. It got my truck’s tires well off the ground for easy removal. The dual pump pistons make a noticeable difference; you get to the load much faster than with a single-piston jack. It’s not instant, but it significantly reduces the time and effort spent pumping.
Portability and Handling
At 63.56 pounds, it’s a substantial piece of equipment. The compact design (26.4 x 11.4 x 7 inches) makes it easier to store and maneuver into position than a bulkier jack, but you still feel the weight when carrying it. The hybrid steel/aluminum construction helps, but calling it “lightweight” is a stretch—it’s portable for its capability, not in an absolute sense.
Build Quality and Durability
The hybrid construction feels Solid. The steel components take the stress, while the aluminum parts seem to keep the overall weight in check. The locking adjustable height adapter works smoothly and feels secure in its four positions. Based on my use, it feels built to handle the 2-ton load and the abrasion of off-road environments without issue.
Who Should Buy This Generator?
Not every jack is right for every job. Based on my time with it, here’s who will get the most out of this tool and who might be better served by something else.
✅ This Is a Great Fit If You…
- Own a truck, SUV, or off-road vehicle and regularly work on it in a driveway, yard, or trail, not a smooth garage floor.
- Need a stable 28.4-inch lift to comfortably access suspension components, differentials, or to remove large tires.
- Value a compact storage footprint but don’t want to sacrifice lifting height or capacity.
- Want the confidence of a full-length steel skid plate when working on gravel, sand, or uneven ground.
❌ You Might Want to Look Elsewhere If…
- You only work on pavement in a garage and need a super low-profile jack for sports cars.
- Absolute minimum weight is your top priority, as the 63.56-pound heft is noticeable when carrying.
- You need to lift vehicles or equipment that exceed its 2-ton (4,000 lb) capacity rating.
My top recommendation is for the weekend warrior or off-road enthusiast who needs a dependable, stable lift away from the shop. The SUNEX Tools 6602RJ is built for that exact scenario and performs it brilliantly.

Common Issues & Fixes
Even a well-built tool can have hiccups. Here are a few things I ran into or can foresee, and how to handle them.
Jack Won’t Lift or Loses Pressure
The problem: The handle pumps but the saddle doesn’t rise, or it slowly sinks under load.
My fix: First, check the release valve is fully closed. If it still leaks down, there’s likely air in the hydraulic system or a seal issue. You’ll need to “bleed” the jack following the manual’s procedure, or contact support if it’s a new unit.
Saddle Slipping on Uneven Surfaces
The problem: The jack’s rubber pad or the locking adapter slips when positioned on an angled surface.
My fix: Always use the 4-position locking adapter to get the saddle as level as possible before lifting. For extra grip on a smooth axle or frame, place a small piece of rubber or a wood block between the saddle and the load.
Difficulty Moving on Soft Ground
The problem: The wide skid plate, while stable, can drag or dig in when you’re trying to roll the jack into position on dirt.
My fix: Don’t try to drag it. Lift it by the frame or saddle to reposition it. The compact 26.4-inch length helps, but at 63.56 pounds, it’s a lift-and-carry situation on anything but pavement.
Locking Height Adapter Feels Stiff
The problem: The 4-position locking mechanism is hard to adjust or doesn’t click securely into place.
My fix: A little lubricant on the sliding mechanism and locking pin usually solves this. Make sure no dirt or debris is jammed in the tracks, which is common after off-road use.
Warranty & Support
The product comes with a 1-year manufacturer’s warranty. SUNEX Tools has a customer service line for warranty claims and parts. For issues, I’d recommend contacting the seller (like Amazon) first within the return window, then reaching out to SUNEX directly for longer-term support.

Frequently Asked Questions
What’s the actual weight of this jack?
It weighs 63.56 pounds. The hybrid steel/aluminum construction helps, but it’s still a solid piece of equipment. It’s more portable than a full-steel jack with the same capacity, but you’ll definitely feel the weight when carrying it any distance.
Will this jack work on a perfectly flat concrete garage floor?
Absolutely, it works fine on concrete. However, its main advantage is the full-length steel skid plate designed for unstable ground. If you only work on smooth garage floors, you might find a dedicated low-profile garage jack to be a better (and often less expensive) fit.
What’s the minimum saddle height?
The product data doesn’t list a minimum height, but with the adjustable height adapter in its lowest position, I found it starts quite low. The compact 7-inch body height helps it slide under most trucks and SUVs without issue. For very low vehicles, you’d need to check the specific clearance.
Is the 2-ton capacity enough for my full-size truck?
For most half-ton and three-quarter-ton pickups and SUVs, yes. A 2-ton (4,000 lb) capacity is meant for one corner of the vehicle, not the entire weight. As long as your vehicle’s corner weight is under that limit, you’re safe. It’s a great fit for most full-size trucks and SUVs used for typical maintenance.
How does the locking height adapter work?
It’s a simple but effective sliding extension on the saddle with four pin-lock positions. You pull a pin, slide the adapter up or down to match your vehicle’s lift point height, and re-insert the pin. This gets the saddle close to the load before you even start pumping, which is safer and more stable.
What’s included in the box?
You get the jack itself, labeled as the “SUNEX TOOLS 6602RJ 2 Ton Off-Road Jack,” as a single unit. The locking adjustable height adapter is attached. You typically need to add hydraulic fluid yourself (check the manual) and you’ll need a jack stand for safety—never work under a vehicle supported only by a hydraulic jack.
My Final Verdict
After testing it, I’m confident the SUNEX Tools 6602RJ 2 Ton Off-Road Jack is a top-tier tool for its specific job. The 28.4-inch lift and full-length steel skid plate make it incredibly stable and useful for off-pavement work on trucks and SUVs. I’d strongly recommend it to any off-road enthusiast or homeowner with an unpaved driveway. I would not recommend it for someone who only works on low sports cars in a pristine garage.
The 63.56-pound weight is its main drawback, making it a chore to carry far. However, that weight and the hybrid build contribute to its rock-solid feel when lifting. For the stability and high lift on soft ground, I’d buy it again in a heartbeat.
