Want lift plus power and performance? High Lifter engineered a gearing setup for a 6'' portal with 45% gear reduction. You can run a larger tire size between a 33'' and 39'' and have the torque and horsepower you need. This robust set of portals gives height and power in any terrain. For the mud rider, you're geared to get out of the thickest mud holes with 6'' of height to pass over anything that comes in your way. For the rock climber, a 45% gear reduction gives you the power to ease right over rocks and boulders, plus added lift to run big tires and go places your friends can't.
There may be a two week lead time on this product.
What does the 45% Dual Idler Gear Lift offer?
- High Lifter improved the portal design by adding a second idler gear in the gear box
- The dual idler gears spread the load over twice as many teeth on the gear sets, which doubles the area and reduces stress by half.
- You gain more reliable torque transfer
- If you run a 40” tire or larger, this is the ideal gear ratio and the dual idler gears are almost a must
- Stop burning up belts and breaking so many axles; differentials; drive shafts; snorkel gears…
- 45% Gearing extends brake life by needing brakes less often due to greatly improved engine braking
- Even though a lower gear ratio will get your speedometer closer to a stock reading, that is still too high a gear to offset the loss of torque caused by the larger tires. If you don’t have a need to run fast, a lower ratio performs better and give you the power you want!
Why is this 6” kit better than our competitor?
Forged Gear Boxes
- Strongest boxes on the market because forging produces a tougher piece of metal
- Forging is stronger than both cast and billet aluminum
- Competitors use cast aluminum and billet aluminum boxes
- These portal boxes are extremely robust and give you more worry-free miles than any other portal
Gear Box Venting
- Customers asked for box venting and we give you the option
- Our box design offers a plug for venting with an optional easy to install kit that will be available soon
- Vent kits allow an advantage of cooling which reduces early deterioration of the gaskets and seals
Gasket Material and Design
- High density Kevlar fiber gaskets plus no additional sealant is needed
- Gasket material is creep resistant plus oil and coolant resistant
Seals
- Two oil seals on the spindle shaft for 100% more sealing area
- Dual seals prevent water intrusion and oil leaks
- True triple seal on the input shaft which includes a wiper seal that provides a significant extra layer of protection
Backing Plate
- These are the strongest backing plates on the market
- 5/16” steel plate with Bent flanges for strength and durability
- Welded gusset brackets and designed to factory off-set
- Works with all control arms that are built to factory hub specifications
13” Rotor
- Precision ground stainless steel rotors (this is a big deal for brake performance)
- Access holes for ease of assembly and disassembly
- Slotted rotor allows for heat dissipation and cooling
Gear Profile
- Alloy steel heat treating process increases overall internal and external strength
- CNC precision ground machining ensures excellent fitment and increased strength
- Controlled gear lapping for ease of installation and a quieter performance.

Not Squeakable for Mini/Toy Aussies
Size: Medium (VALUE 2-Pack), Style: Chicken
Very durable and good squeaker. However, too large and hard for my Mini Aussies to squeak. My Aussies love their squeaky toys, unfortunately not this one.

Not indestructable, but very sturdy
Size: Medium, Style: Beef
I have recently been blessed (and cursed) with my first Super Chewer dog, a year old Australian Shepherd. She will chew herself out of boredom, so it's imperative we always have sturdy toys readily available for her, preferably in every room.
Playology and Kong by and large have been the best toys we can find for her. Kong has a very good rubber ball, bone, and ring that have held up spectacularly (no noticeable damage after months of use, except maybe some pin-prick teeth marks). Dogs need a wide range of textures though for enrichment, so we've been dabbling with the Playology line (the tire, plush bone, dry-tech rope), including this ball.
The scent factor is definitely interesting. Most people know Playology for the peanut butter scents, so I was very excited to find a multitude of flavors available on Amazon, especially with the different scents clearly labeled. I choose the red or beef flavored since the only two in the medium size in stock at the time were beef and sweet potato. The scent is indeed noticeable to humans, but it's not too strong or overwhelming on its own (walking down the Playology aisle in Petsmart can be overwhelming though since they have dozens of dozens of scented toys, much like going down a candle aisle).
I can't speak for the dog on how she feels about the scent, but she took to the ball immediately, same as the normal peanut butter ones we get. The medium size is pretty much perfect for her (she's just under 50lbs). It's got decent bounce for playing fetch in the house, but not so bouncy that we're afraid to use it in the house. It's got a decent density to it as well that adds to the sturdiness.
The biggest issue is the squeaker. It's not an obnoxious squeaker by any means, and the dog enjoys it very much. However, when you put a squeaker in any toy, it reduces the density and creates a weak spot dogs can exploit. She did good with the ball at first and was able to sit and chew on it for minutes as a time without doing any real damage (her teeth leave lots of pin-prick teeth marks, but they don't do any real damage to the ball, just superficial marks).
Aussies are considered incredibly smart though, and it didn't take her long to learn she could rip out the bottom of the ball where the squeaker is sealed inside to tear the squeaker out, thus ripping the squeaker apart and compromising the structural integrity of the ball. We're debating if we want to toss the ball in the trash or attempt letting her play with it in a supervised session without the squeaker to see if it is safe.
So, overall, this is a very tough ball. It does accumulate teeth marks that are essentially harmless, but there is a weak spot in the seam where the squeaker is inserted, which means this is not indestructible. It is by and large a great ball for fetch and likely won't ever be destroyed unless a dog is left with it long enough to chew a hole through that squeaker seam. Playology balls are pretty costly though, so the risk of it becoming unusable once the squeaker is ripped out is a bit off-putting. The bright side is that if you monitor your dog, you can likely get several weeks or months of use out of the ball; just no unsupervised play sessions.
7/10, durable, bouncy, and the scent keeps the dog interested, but the ball is not good unsupervised as it can be destroyed if the squeaker is ripped out. We will continue to buy Playology toys, but we will likely not buy too many of these balls until a more durable one (maybe without a squeaker) is released.

No. Just no. My own dog shamed me…
Size: Medium, Style: Beef, Size: Medium, Style: Beef
My German Shepherd likes squeaky balls. She has lots of them. Most are similar to a tennis ball. By the way, don’t give your dog an actual tennis ball. The outer material is made for grip for tennis. It’s abrasive and is not good for your dog’s teeth enamel at all.
Anyway, for $14.99, I thought I’d give this one a try. The pictured packaging alone was an eye grabber. The picture you see on Amazon is a cardboard with item specific info on the card: flavor, size, what it is (squeaky ball). The pictured product also has a hole in the card to secure and present the item the card describes. Even two color coded red zip ties securing the ball in the card hole. Awesome presentation and frankly that’s what made me give this a shot. So, as far as the presented product/packaging on Amazon, great job! I even sent a link to a buddy and he bought one too.
Well, I cannot speak for everyone, but what I received was what’s pictured with my review. A red ball in a clear bag, along with a card that describes the product line. Nothing specific to what I actually bought (like the slick item-specific packaging on Amazon. To find that, I had to read the condensed description on the Amazon specific bar code that is right on top of a different barcode. This kind of thing displeases me. I want what grabbed my attention on amazon. No, this was not a return. This is how they come.
I figured with item specific info on the packaging, the company is putting some money into packaging that makes you feel like you bought something specific. Pictured one says all natural beef. The chicken one says chicken. Pictured one says the size. Heck, I’d of been happy to at least have the ball attached to a card that at least says it’s a squeaky ball. Nope.
Cost cutting is not ok when you are selling a beef flavored, medium size squeaky ball for $14.99.
What arrives is an advertisement for the whole line, nothing that says what it is, the flavor, the size (unless you try to make out the Amazon bar code desc). Just a ball in a bag with an advertisement to buy other stuff they make.
Maybe you received what’s pictured. I texted my buddy and asked him what he received. The exact same thing I did.
In my opinion, when one cuts corners on packaging, I have no doubt corners could have been cut with the product itself. The squeak isn’t as easy as kong ball squeaker. Takes effort. So if your dog likes to play by walking/running around while constantly biting and getting that pleasing squeak each time, that didn’t happen here. Yes, I know the tennis ball type squeakers are different. But this says it’s a squeaker ball. Not just a squeaker ball, but a flavored squeaker ball. Mine smelled like rubber. Where’s the beef?
I threw it a few times. My dog chased it a bit, did her usual “what’s this” evaluation, bit into it a few times with her very strong jaws, only to have no squeak. God as my witness, she dropped it, looked at me with what I insist is a look of disappointment, and walked away. She then went to the big bin of a huge variety of squeaky balls and grabbed one. She then went upstairs, with a squeak every second or so as she went up.
I went and picked this one up with slobber and all. To get this to squeak requires opposing thumbs. So I suppose it could be marketed as a hand strengthener that squeaks.
Friends lab had zero interest as well. So, I’m gong to actually return a dog toy. This was a disappointment. If it had come carded the way it shows on Amazon, I would not be as frustrated. I won’t take a chance when corners are cut when it comes to my dog. Update the picture to what I received is my advice to the company. I have a feeling what I got wouldn’t sell as easily.
Topping it off, I noticed something odd. It doesn’t squeak when squeezing it, only when it is released to go back to its regular shape. So it’s a reverse reward. Weird. All the squeaker balls we have make a noise both when squeezing and releasing.
Sorry Olina (my pooch).

Best Toy EVER!
Size: Jumbo, Style: Peanut Butter
I was a bit skeptical. We have had NO joy in finding toys for "aggressive" chewers that actually last more than a day for our 1 year old Staffordshire/Pittie mix. He has jaws of iron! (or so it seems) Nothing holds up. He is literally eating them, and subsequently gets them taken away, within 24 to 48 h ours. IF that long. He finds it a challenge to get to the center of whatever toy he has, whether it is supposed to have a center or not! We bought this in April of last year!! Yes, the squeaker is no longer squeaking (a blessing in disguise) but the ball itself is still intact, with no nicks, dings, pieces missing, etc. It still bounces well, and he still loves it. 1 year later, still going strong! I didn't realize it had been that long, until today. So I had to write a review, and buy a couple more Playology Jumbo toys. I hope they hold up 1 tenth as well!

I’ve purchased this item multiple times. Twice now, I got duds. Within minutes of opening the package, the ball was destroyed. The other times, it lasted months! I don’t know how to explain it.
