High Lifter Portal Gear Lift (Each kit includes 4 portal boxes)

15% & 30% Dual Idler Reductions

What does the 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
• Stop burning up belts and breaking so many axles; differentials; drive shafts; snorkel gears…
• Gear reduction 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 4” 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

Rotors

• 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
