Transform Your Can-Am Defender with GDP Portals
Redefine your off-road experience with the Can-Am Defender 4" Portal Gear Lift from GDP. Engineered for extreme performance, these portals provide unmatched strength and reliability for serious UTV enthusiasts. With patented dual idler portals, you get superior torque transfer, reduced drivetrain stress, and compatibility with tires up to 38 inches.
Dual Idler Portals for Maximum Strength
GDP’s innovative dual idler gear system spreads load across two idler gears, increasing durability and torque handling. Precision CNC-ground 9310 steel gears ensure smooth, quiet operation, while 4340 hardened steel drive shafts provide unmatched strength for aggressive trail, mud, or dune riding. Choose between a 15% gear reduction for faster speeds or a 30% reduction to power massive tires effortlessly.
Protect Your Drivetrain and Enhance Performance
By placing gear reduction at the hub, GDP portals reduce wear on your transmission, prop shaft, differential, and axles. The result is more power to the wheels, longer-lasting drivetrain components, and a smoother ride—even with oversized tires. The dual idler configuration adds a 1.5-inch total offset, increasing clearance and accommodating larger wheels without compromising handling.
