if you are doing a tune use a Talon ECU with IGR solves shifting issues and you can remove the torque management. Then you don’t need to rebuild/change oil in portals, don’t have steering issues or ball joint problems associated with larger tires with the additional forces the portals put on the suspension.
IF you’re in the mud all the time portals are fine but other than that look at IGR and a Talon ECU
IGR won’t give me ground clearance, isn’t easily reversible and requires ECU or programming changes to make it work correctly.
Portals gave me ground clearance, is easily reversible and requires no ECU or programming changes.
Yeah I have to change the oil in them after every 3rd or 4th ride. Takes an hour and $15 in oil.
Good and bad in both. Portals are better for me and no internal work or grinding 🤷🏻♂️
