This High Lifter 4'' Portal Gear Lift is made tough and ready for any challenge. Now engineered with a gearing setup that allows two idler gears in the portal box to spread the load between twice as many teeth on the gears. This doubles the area and reduces the stress by half, allowing more abuse. This kit is for riders who are looking for torque and power.

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

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
  • 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…
  • 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!
