Product Description
Unleash the full potential of your Can Am Defender HD11 with the ultimate mud-crushing, trail-conquering upgrade: the High Lifter Dual Idler 4-Inch Portal Gear Lift. Built for riders who refuse to compromise, this portal lift delivers the ground clearance you crave while radically upgrading your drivetrain’s strength. At the heart of this beast is the dual idler gear configuration, which intelligently spreads the load over twice as many teeth on the gear sets. By doubling the surface area and reducing gear stress by exactly half, you get a much more reliable torque transfer and the peace of mind needed to throttle through the deepest pits. Plus, with 15% or 30% gearing options, you'll experience greatly improved engine braking that naturally slows you down, extending your brake life and keeping you in total control.
Holding it all together is the strongest backing plate available: a heavy-duty 5/16-nch steel plate featuring bent flanges, welded gusset brackets, and a factory off-set design that seamlessly pairs with most control arms built to stock hub specs.
Engineered for Unmatched Strength & Performance
Every component of this portal system is meticulously engineered to endure extreme off-road abuse. The gearboxes are the strongest on the market, crafted from forged aluminum that inherently outperforms both cast and billet alternatives for worry-free miles. Inside, CNC precision-ground alloy steel gears undergo a specialized heat-treating process and controlled gear lapping, ensuring an flawless fit, maximum strength, and a noticeably quieter performance. The boxes also feature a plug for venting, perfect for pairing with our upcoming, easy-to-install vent kits that cool the system and prevent early deterioration.Holding it all together is the strongest backing plate available: a heavy-duty 5/16-nch steel plate featuring bent flanges, welded gusset brackets, and a factory off-set design that seamlessly pairs with most control arms built to stock hub specs.
Bulletproof Sealing & Superior Cooling
- Advanced Gasket Technology: High-density Kevlar fiber gaskets provide extreme creep, oil, and coolant resistance without needing any additional messy sealants.
- Dual Spindle Seals: Two oil seals on the spindle shaft create 100% more sealing area, effortlessly preventing water intrusion and oil leaks.
- Triple Input Protection: A true triple seal on the input shaft includes a dedicated wiper seal, offering a significant extra layer of defense against mud and grit.
- Premium Slotted Rotors: Precision-ground stainless steel rotors feature integrated access holes for easy assembly, alongside a slotted design that maximizes heat dissipation to keep your brakes running cool.
