Installed 37's on Gen3 35 Raptor - no issues.

Before and after. OEM 37" wheels and tires with RPG 1.5" collars in the front

For an experiment on how much offset these trucks can handle I put 1.75” wheel spacers on my stock suspension base 2024 with 37” K02’s and it didn’t rub.

So I just bought a set of 37 x 12.50 R17 toyo open country RT trails. Plan on getting some Method 703s in 8.5 width with a +25 offset - based on anyone's experience can I stuff them without doing any suspension work? Eventually I plan on SDI tophat + E-Click but not sure if I can get away with just wheels and tires now or do everything at once - this is a 21 35 package truck
