Want lift, plus power and performance? These 6-inch portal lifts are a fan-favorite for mudding, trail riding and running larger tires and wheels. High Lifter portal lifts provide excellent clearance as well as more throttle response at lower speeds while covering tough terrain. Adding portals to your rig is the best way to gain extra clearance from the wheel bearings on up. With the added height starting right at the wheel mount, even the a-arms and shocks are lifted.
 
Gear Reduction 45% or 60%
High Lifter engineered a gearing setup for a 6'' portal with 45% or 60% gear reduction. You can run a larger tire size between a 33 to 39 inches at 45% and 40" and bigger at 60%, and have the torque and horsepower you need. The 45% gear reduction is a robust set of portals giving height and power in any terrain. Mud Riding geared to get you out of the thickest mud holes and 6 inches of height to pass over anything that comes in your way. Rock Climbing 45% gear reduction makes that rocky terrain seem easy. You’ll have the power to ease right over rocks and boulders, plus added lift to run big tires to go places your friends can’t. Like any other portal kit, there will be a reduction in top speed when running the 6” Dual 60% gears. This kit is for riders who are looking for torque and power. The dual 60% is perfect for the hardcore mud rider that wants to hit the holes hard and come out on the other side!
 
When choosing a dual idler set up, you also gain:
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!
 
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
 
Note: High Lifter strongly recommends pairing this High Lifter Portal Gear Lift with a High Lifter Frame Stiffener Kit. Reinforce your frame to save yourself from a potentially expensive repair!
