High Lifter Portal Gear Lift
(Includes 4 portal boxes with 15% or 30% Dual Idler Reductions)

Why Choose Dual Idler Gears?
Stronger Design: Two idler gears instead of one = twice the gear teeth engaged, which reduces stress and boosts strength.

Better Torque Transfer: Handles more power without damaging belts, axles, differentials, or drive shafts.

Improved Engine Braking: The gear reduction helps slow the machine without relying on brakes as much.

More Power with Bigger Tires: Lower gear ratios help regain lost torque caused by oversized tires — perfect if you're not chasing top speed.

What Makes High Lifter’s 4” Kit Better?
Forged Gear Boxes

Built from forged metal — stronger than cast or billet aluminum (which most competitors use).

Toughest portal boxes available for maximum durability and performance.

Gear Box Venting (Optional)

Comes with a plug ready for a vent kit (coming soon).

Vents help keep internals cool and extend seal and gasket life.

Kevlar Gaskets

Made from high-density Kevlar fiber.

No extra sealant needed.

Resistant to oil, coolant, and pressure.

Heavy-Duty Seals

Dual oil seals on the spindle shaft = twice the protection.

Triple-sealed input shaft includes a wiper seal to block water and leaks.

Reinforced Backing Plates

Thick 5/16" steel with bent flanges for added strength.

Welded gussets.

Designed to match factory hub specs and fit most factory-style control arms.

Precision Rotors

Stainless steel, precision-ground for excellent brake performance.

Slotted for cooling and built-in access holes for easier servicing.

High-Strength Gear Profile

Made from heat-treated alloy steel.

CNC machined for perfect fit.

Lapped for smoother, quieter operation.
