Installation Instructions

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.

                            Good size ball for my big boy
                            Color: Purple
                            My big boy loves this ball. He chews and chews and chews on it and it ain't made a dent in it. It's made a good quality rubber. It's got a squeaker in it. He hasn't managed to get it out which is not normal because normally he can get a squeaky out within 10 minutes. He goes through toys like I don't know what so it's being being a good. Really good ball. We've had it for about 2-3 months now and he hasn't been able to break into it and get squeaky out or even make a dent into it. That would tear up the the rubber

                            Sturdy ball, holding up well.
                            Color: Purple
                            I have a ball obsessed Shih Tzu. This has become his security blanket. He literally takes it everywhere and even sleeps with it next to him. Dexter loves any ball. All shapes and sizes. He will play fetch all day long if you let him. He doesn't know when to quit. It can be 100 degrees out with 80% humidity and he'll fetch all day long. This is a larger ball, I think just over 3 inches. It is entirely too big for a Shih Tzu, but it is perfect for Dexter. He came to us with a ball similar to this that he has since lost. He carries it in his mouth by placing his incisors in the indentations and lets it hang out the side of his mouth. Quite comical actually, but it works for him. We have bought him balls more for his size, but they're too small and he gets them lost under cabinets, furniture or any nook and cranny the ball will fit. And being obsessive, he will bark and carry on because he can't get to the ball until you come and rescue it. Difficult on our old knees. So he ends up getting the smaller balls taken away from him. The other night he was laying and chewing on this ball. It sounded like he was shredding this ball to pieces. I was afraid he would choke or swallow the rubber pieces, so I took it away from him. There wasn't anything wrong with the ball. It looked brand new. No chew or bite marks that I could see. I was impressed. It does have a squeaker, but I can barely get it to squeak and I have strong hands. A larger dog with a stronger bite force could probably easily make it squeak. It claims to have a beef scent to the toy, and maybe that is why he likes the ball so much. But I sniffed it and couldn't smell anything, which is fine by me, it won't have an obnoxious smell to where I don't want it around me.

                            Color: Orange
                            Most dogs love to play with balls. This is a ball. It squeaks and can handle a lot of strong chewing. Quite durable and a good size for medium and up sized dogs. (Honestly even smaller dogs would have fun with this).

                            Color: Purple
                            Heavy duty toy. This ball has some weight to it! I have a smaller laber doodle that thinks she's a German Shepard so no toy is too big or heavy for her. She's been chewing on this for months but you'd never know it. The squeaker is even hard for me to activate with my hands. She hits it in the right spot every now and again and gets excited about it. Great if your not crazy about hearing a squeaker squeaking non stop!
