Frequently Asked Questions

Most 4" and 6" portal kits require 14-inch or larger wheels. Additionally, you typically need a wheel with a specific offset (usually 5+2 or similar) to ensure the tire clears the portal box and steering components. Always check your specific kit’s requirements before purchasing.
It depends on your tire size. For 35-inch tires, a 30% reduction is the industry standard to regain lost torque. If you are stepping up to 37-inch or 40-inch tires for extreme mud or rock crawling, a 45% or 60% reduction is recommended to protect your factory axles and transmission.
Unlike a bracket lift that puts stress on your CV axles by increasing their operating angle, a Portal Gear Lift provides lift at the wheel hub. This keeps your axles at factory angles while providing a built-in gear reduction that actually reduces stress on your drivetrain.
