With a built-in gear reduction and 6 inches of lift, you get more torque, improved ground clearance, and the ability to run bigger tires without overloading your machine. Pick between a 15% or 30% gear reduction to match your riding style, and for extra durability, swap the cast housing for our billet aluminum option. Plus, you can upgrade to our Dual Idlers for maximum strength and performance.\u003c\/p\u003e\u003cp\u003eWhat Is a Dual Idler?\u003c\/p\u003e\u003cp\u003eIt’s all about the details with our dual idler gear portals. Two idler gears mean the load is spread out, giving you a stronger setup—but only if they mesh perfectly. That’s why we rely on precision CNC grinding and 9310 steel to make sure every gear is just right.\u003c\/p\u003e\u003cp\u003eDesigned to Match Your Riding Style\u003c\/p\u003e\u003cp\u003eGDP Portal Gear Lifts are built to handle every kind of riding. From dunes and mud to fast trails and daily work, there’s a setup to match your needs. Choose a 15% gear reduction for quicker acceleration with plenty of torque, or a 30% reduction for maximum power and massive tires.\u003c\/p\u003e\u003cp\u003eYour Drivetrain Stays Protected\u003c\/p\u003e\u003cp\u003eBy placing the gear reduction directly in the wheel hub, GDP portals reduce the load transferred through the drivetrain. This design helps protect important parts like your axles, differential, prop shafts, and transmission by limiting the strain caused by oversized tires.\u003c\/p\u003e\u003cp\u003eBuilt Tough with Aluminum and Steel\u003c\/p\u003e\u003cp\u003eWe built these portals to take a beating.

A 4-inch portal gear lift gives you both ground clearance and torque—not just height like a standard lift kit. By moving the gear reduction to the hub, portals reduce stress on axles, differentials, and the transmission while allowing you to run larger tires with confidence.\u003c\/p\u003e\u003cp\u003eWill this portal gear lift fit my Can-Am Defender 4 or Defender MAX?\u003c\/p\u003e\u003cp\u003eThis portal gear lift is machine-specific and engineered to fit select Can-Am Defender and Defender MAX models listed in our fitment guide. Always check the fitment tab on the product page to confirm compatibility with your exact year and model.\u003c\/p\u003e\u003cp\u003eHow hard is it to install a SuperATV 4-inch portal gear lift?\u003c\/p\u003e\u003cp\u003eInstalling portals is more involved than a basic lift because they replace the hubs and integrate gear reduction. We include detailed step-by-step instructions, extended brake lines, and all required hardware to make installation as straightforward as possible for experienced DIY riders.\u003c\/p\u003e\u003cp\u003eWhat gear reduction options are available and how do I choose one?\u003c\/p\u003e\u003cp\u003eWe offer 15% and 30% gear reduction options. A 15% reduction maintains higher trail speed with added torque, while 30% is ideal for heavy loads, mud riding, or turning larger tires that require more low-end power.\u003c\/p\u003e\u003cp\u003eHow much wider does the Defender get with this portal gear lift installed?\u003c\/p\u003e\u003cp\u003eThis 4-inch portal gear lift increases width by approximately 4 inches per side, giving your Defender a wider, more stable stance. The added width improves control when running larger tires or navigating uneven terrain.\u003c\/p\u003e\u003cp\u003eWhat makes SuperATV GDP portals stronger than other portal lifts?\u003c\/p\u003e\u003cp\u003eGDP portals use precision-ground 9310 alloy steel gears and offer a dual idler configuration that spreads load across more surface area. This engineering delivers smoother operation and maximum strength under extreme torque, backed by years of real-world testing.\u003c\/p\u003e\u003cp\u003eDo I need special wheels or backspacing for this portal gear lift?\u003c\/p\u003e\u003cp\u003eYes. Wheels must be at least 14 inches in diameter and cannot exceed 4.5 inches of backspacing. Following these requirements ensures proper clearance, correct steering geometry, and long-term reliability of the portal system.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eAvailable with billet or cast aluminum housing\u003c\/li\u003e\n\u003cli\u003eDual idler gear configuration maximizes strength\u003c\/li\u003e\n\u003cli\u003eCool, quiet, precision ground gears made from 9310 alloy billet steel\u003c\/li\u003e\n\u003cli\u003e1.5 in. diameter 4340 hardened steel drive shaft\u003c\/li\u003e\n\u003cli\u003eHousings use advanced gaskets or O-rings that don’t let anything through\u003c\/li\u003e\n\u003cli\u003eUniversal hubs can be set up to work with the following bolt patterns: 4\/156, 4\/137, 4\/115, and 4\/110\u003c\/li\u003e\n\u003cli\u003eGear reduction reduces stress on your drivetrain\u003c\/li\u003e\n\u003cli\u003eDual idler gear configuration adds a 3\/4” front and rear offset—1.5” total extension\u003c\/li\u003e\n\u003cli\u003eLighter than the competition\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment (per SuperATV)\u003c\/h3\u003e\u003cp\u003eCan-Am Defender HD 7 : 2022+ Can-Am Defender HD 7 DPS : 2022+ Can-Am Defender MAX HD 7 : 2022+\u003c\/p\u003e\u003ch4\u003eWheel Requirements\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e14” or larger wheel required\u003c\/li\u003e\n\u003cli\u003eWheels cannot exceed 4-1\/2” backspacing\u003c\/li\u003e\n\u003cli\u003eNot compatible with dual beadlock wheels\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003ca href=\"https:\/\/madmin.superatv.com\/amfile\/file\/download\/file\/9502\/product\/164871\/\" target=\"_blank\" rel=\"noopener\"\u003eInstallation instructions (PDF)\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e\u003cem\u003eShips free from SuperATV.
