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.
