If you can find a part number then I would expect the ability to order it. Just need to find the right person to help you get that info. Would also expect the aftermarket to offer something as well. Maybe that 4WP person on this board might be able to help? Or maybe @flip ?
Ok. Thank you. Real world I would think th at your "fine" of not really flexing the suspension (IIRC you don't really plan on it). But if you dropped the rubber to a 275 and a 60/65 should be cool. Maybe ping @Discount Tire for direct questions? 😉
These might be a concern about the robustness of the 7 speed with the Squatch wheels. Other than that the Squatch travel limiter/lift has been debated for quite some time.
