I’ve been wrenching on stubborn bolts for years, and I know the pain of a stuck fastener in a tight spot. That’s why I grabbed both the ARES 40009 Extendable Breaker Bar and the Powerbuilt 641700 Ratchet Breaker Bar to see which one saves my knuckles. The ARES stretches from 16 to 24 inches with a twist lock, while the Powerbuilt stays at a fixed 24 inches but adds a ratcheting flex head.
This comparison is for anyone who needs maximum torque in cramped engine bays or under a truck. The big trade-off is simple: do you want adjustable length or a ratcheting, multi-angle head? Let me break down exactly how these two heavy hitters compare so you can pick the right tool for your next job.

Full Specs Comparison
Let’s lay out the numbers side by side. I’ve pulled every spec from the product pages so you can see exactly what each tool brings to the table.
Right away I see the big difference: the ARES gives you adjustable length from 16 to 24 inches, while the Powerbuilt packs a ratcheting mechanism and a flex head with 7 locking positions. Both are built from chrome vanadium steel, but the Powerbuilt is noticeably heavier at 3.15 lbs compared to the ARES at 1.22 kg (about 2.69 lbs).
Individual Product Breakdown
I spent time wrenching with both of these bars in my garage, testing them on rusted suspension bolts and tight engine bay fasteners. Here’s what I found with each tool.

The ARES extendable bar is my pick for anyone who works in tight, awkward spaces. The twist lock lets you go from 16 to 24 inches in seconds, and the chrome vanadium steel handle feels solid when you lean into a stuck bolt. I love the swivel head — it gives you good range of motion even when you’re crammed between a wheel well and a frame rail. My only gripe is that it doesn’t ratchet, so you have to reposition the socket after each swing.
✅ Pros
- Adjustable length from 16 to 24 inches for tight spots
- Twist lock mechanism is quick and easy to use
- Chrome vanadium steel with powder coated handle is durable
- Lightweight at only 1.22 kg (2.69 lbs)
❌ Cons
- No ratcheting mechanism — you have to reposition each time
- Only fixed square head, not a flex head

The Powerbuilt is a beast for breaking loose rusted bolts thanks to its 24-inch length and 36-tooth ratcheting mechanism. I love the flex head with 7 locking positions — it got me into angles the ARES couldn’t touch, especially around exhaust manifolds. The spiral-machined grip is a nice touch when your hands are greasy. But it’s heavier at 3.15 lbs and doesn’t adjust in length, so it’s less versatile for tight storage or varying reach needs.
✅ Pros
- 36-tooth ratchet mechanism for smooth, fast work
- Flex head with 7 locking positions for awkward angles
- Spiral-machined no-slip grip handles oily hands well
- Mirror-polished chrome finish resists corrosion
❌ Cons
- Fixed 24-inch length — no adjustability for tight spaces
- Heavier at 3.15 lbs, less portable than the ARES
Which One Should You Buy?
I’ve tested both of these bars side by side, and honestly, the right pick comes down to where you work and how you like to swing. Here’s how I’d match each tool to a specific kind of mechanic or DIYer.
ARES 40009 Extendable Breaker Bar is right for you if…
- You often work in cramped engine bays or wheel wells where a fixed 24-inch bar won’t fit — the ARES shrinks down to 16 inches.
- You need a lightweight tool to carry around the shop or in a service truck — it’s only 1.22 kg (2.69 lbs).
- You prefer a simple, no-nonsense breaker bar without a ratcheting mechanism that could bind up over time.
Powerbuilt 641700 Ratchet Breaker Bar is right for you if…
- You’re dealing with rusted exhaust bolts or suspension parts where the 36-tooth ratchet saves you from resetting the socket after every swing.
- You need a flex head with 7 locking positions to reach fasteners at weird angles, like on intake manifolds or starter bolts.
- You prefer a no-slip spiral-machined grip when your hands are covered in oil or grease.
❌ Who Should Skip All of These?
If you mostly work on light-duty home projects or just need to tighten lug nuts on your car, a standard socket wrench or a compact 1/2-inch ratchet will serve you better. Both of these bars are overkill for simple jobs and will just take up space in your toolbox.
For the most common buyer who wants versatility, I’d grab the ARES 40009. That adjustable length from 16 to 24 inches is a big improvement for tight spots, and the chrome vanadium steel build means it’ll last through years of hard use.
Frequently Asked Questions
Which is better for tight engine bays — the ARES extendable or the Powerbuilt ratchet bar?
I’d take the ARES 40009 for tight engine bays every time. Its telescoping design lets you collapse it down to 16 inches, which fits between a radiator and engine block way easier than the Powerbuilt’s fixed 24-inch length. The twist lock is quick to adjust, so you can shorten it for cramped spots and extend it for more Use when you have room.
Is the Powerbuilt ratchet breaker bar worth the extra money over the ARES?
It depends on how often you deal with rusted fasteners. The Powerbuilt’s 36-tooth ratchet mechanism is a real time-saver on stubborn bolts because you don’t have to reposition the socket after every swing. If you’re regularly working on old cars or heavy equipment, the ratchet and 7-position flex head justify the price difference. But if you just need occasional torque in tight spots, the ARES gives you more flexibility for less.
Which one has a stronger build — the ARES or the Powerbuilt?
Both use chrome vanadium steel, so the core material is equally tough. The ARES has a powder coated handle and chrome plated shaft for scratch and corrosion resistance, while the Powerbuilt uses a mirror-polished chrome finish that’s also very durable. I’d call it a tie on strength — the real difference is the ARES is lighter at 1.22 kg versus the Powerbuilt at 3.15 lbs, so the Powerbuilt feels more substantial in your hands.
Can the ARES extendable bar replace a ratchet breaker bar entirely?
Not if you need a ratcheting action. The ARES is a straightforward breaker bar with a fixed square head — no ratchet mechanism at all. That means every time you loosen a bolt, you have to pull the socket off, swing the bar back, and re-seat it. The Powerbuilt’s 36-tooth ratchet lets you work continuously without resetting, which is a big advantage on long jobs.
Which one is better for removing stuck lug nuts on a truck?
I’d pick the Powerbuilt 641700 for truck lug nuts. The fixed 24-inch length gives you maximum Use, and the ratcheting mechanism lets you break them loose quickly without repositioning. The spiral-machined no-slip grip also helps when you’re putting your full weight into it. The ARES can work too, but you’ll have to extend it to 24 inches anyway, so the adjustable feature isn’t as useful here.
How do the customer ratings compare between these two tools?
Both sit at 3.9 out of 5 stars, so buyers are equally satisfied with either tool. The ARES has 55 reviews compared to the Powerbuilt’s 31, giving it a slightly larger sample size. Neither tool has a clear winner in customer satisfaction — the choice really comes down to whether you need adjustable length or a ratcheting flex head.
My Final Verdict
After testing both bars on rusted suspension bolts, tight engine bay fasteners, and everything in between, I’m giving the win to the ARES 40009 Extendable Breaker Bar. Its adjustable length from 16 to 24 inches solves the biggest problem I face: getting Use in cramped spaces. The chrome vanadium steel build is solid, and at only 1.22 kg it’s easy to carry around. The Powerbuilt 641700 is a close runner-up for anyone who prioritizes ratcheting speed and flex-head access over adjustability.
If you’re on the fence, ask yourself this: do you work in tight spots where a fixed 24-inch bar won’t fit? Then the ARES is your tool. Do you deal with rusted fasteners and want to minimize socket repositioning? Then go with the Powerbuilt. You really can’t go wrong with either — they’re both chrome vanadium steel tools rated 3.9 stars.
