Individual Product Breakdown
Here’s my closer look at each jack. I focused on how they feel to use, their build quality, and who would get the most value from them.

I like this jack for its smart mix of aluminum and steel. At 58.5 pounds, it’s noticeably easier to move around the garage than a full-steel jack. The 3-15/16″ minimum height is a true low-profile spec, letting you easily slide it under a lowered car or SUV. It’s my top pick for the home mechanic who wants a good balance of light weight and strength. The main limitation is that its maximum lift of 18-5/16″ might be just shy for some larger trucks.
✅ Pros
- Lighter weight (58.5 lb) makes it easy to maneuver
- Excellent low-profile clearance of 3-15/16″
- Clear 1-year manufacturer warranty
- Dual piston pump for quick lifting
❌ Cons
- Max lift height is slightly less than competitor
- Higher price point than the A A IN model

This is a solid, no-frills workhorse built from heavy-duty alloy steel. I appreciate its slightly higher 18.25″ maximum lift, which gives you a bit more working room under the vehicle. The dual pump system works well to get the saddle up to the load quickly. It’s best for someone who prioritizes a sturdy, traditional steel jack and doesn’t mind the extra 6.5 pounds of weight. The main drawback is its 6.1″ minimum height, which isn’t truly low-profile and won’t fit under many sports cars.
✅ Pros
- Higher max lift height of 18.25″
- Heavy-duty all-steel construction feels Solid
- Often competitively priced
- Double pump system for quick rise
❌ Cons
- Heavier at 65 pounds
- 6.1″ min height is not low-profile
- Warranty is vague “free replacement”
Which One Should You Buy?
Both jacks are solid, but they serve different types of users. Your choice really comes down to how you’ll use it and what you value most.
Jack Boss 3 Ton Low Profile is right for you if…
- You have a low-slung sports car or sedan and need the 3-15/16″ minimum clearance.
- You want to save your back and prefer the lighter 58.5 lb aluminum/steel build.
- You value a clear, defined 1-year manufacturer warranty for peace of mind.
A A IN 3 Ton Floor Jack is right for you if…
- You work on SUVs or trucks and want the extra half-inch of max lift height (18.25″).
- You don’t mind the 65 lb weight and prefer the feel of a traditional all-steel jack.
- Your primary goal is finding a competitively priced, heavy-duty 3-ton jack.
❌ Who Should Skip All of These?
If you’re lifting vehicles heavier than 6,000 lbs regularly, you need a 4-ton or higher capacity jack. Also, professional mechanics who use a jack daily might want to invest in a premium brand with a longer warranty.
For most home mechanics working on cars and SUVs, I recommend the Jack Boss. Its lighter weight and true low-profile design make it the more versatile and user-friendly choice for the garage.
Frequently Asked Questions
Which jack is truly low-profile for a sports car?
The Jack Boss is the clear winner for low cars. Its minimum saddle height is 3-15/16″, which is a true low-profile spec. The A A IN jack has a listed minimum height of 6.1″, which won’t fit under many lowered vehicles. If you have a sports car or a sedan with a low front lip, the Jack Boss is the only real option here.
Is the Jack Boss worth the higher price over the A A IN?
Yes, for most people it is. You’re paying more for a lighter (58.5 lb vs 65 lb), easier-to-maneuver jack with a much better low-profile design. You also get a clearer 1-year manufacturer warranty. If you need to get under a low car or you move your jack around a lot, the Jack Boss is worth the investment.
Which floor jack has a higher maximum lift?
The A A IN jack lifts slightly higher. It has a maximum lift height of 18.25″, while the Jack Boss lifts to 18-5/16″ (which is about 18.31″). The difference is minimal—less than a quarter of an inch. So, while the A A IN technically wins, it’s not a significant advantage in practice.
Are these jacks safe for my SUV?
Yes, both are rated for 3 tons (6,000 lbs), which is more than enough for most SUVs and light trucks. They both comply with the ASME PASE safety standard. Always use jack stands, but in terms of capacity, either jack can safely handle your SUV.
Which jack is easier to move around the garage?
The Jack Boss is easier to move. At 58.5 pounds, it’s 6.5 pounds lighter than the A A IN. That difference is noticeable when you’re pulling it out from under a workbench or rolling it across the driveway. The aluminum and steel construction makes it lighter without sacrificing the needed strength.
What’s the real difference in the warranty?
The Jack Boss has a defined “limited 1 year manufacturer warranty.” The A A IN lists “free replacement” with no specific time period, which is vague. For a straightforward warranty you can rely on, the Jack Boss offers better, more transparent coverage.
My Final Verdict
After comparing every spec, the Jack Boss 3 Ton Low Profile is my clear winner. Its 58.5 lb weight makes it much easier to handle than the heavier A A IN, and its true 3-15/16″ low-profile design is essential for modern cars. The defined 1-year warranty also provides better peace of mind. The A A IN is a solid runner-up best for someone who only works on higher-riding vehicles and wants a traditional steel jack.
If you’re stuck deciding, ask yourself one question: do you need to get under a low car? If the answer is yes, the Jack Boss is your only real choice. If all your vehicles are trucks or SUVs with plenty of clearance, you could save some money with the A A IN.
