@JeepFan1998 just looking at the fronts, without a bump stop extension, the shocks will take the impact when they bottom out. This can cause damage to the shock piston or valving.
Bump stop extensions are used to prevent whichever of the following comes first
1. Shock bottoming out
2. Tire hitting the fenderwell
The shocks you have selected ( based on my measurements) will bottom out about an inch before the bump stop hits the spring perch. So although you would need to cycle the suspension to make sure the tire isn't going to hit, you are already looking at needing bumpstop extensions.
The reason to cycle is to make sure you don't put too long of an extension in that will limit your max possible up travel. You are already gaining more up travel than stock so loosing some of that to prevent other damage should hopefully keep you equal to or slightly better than stock.
For the front, general consensus is to apply the extension to the spring perch because of potential interference w the spring. On the rear, you can put them above the jounce cup
Is there a reason that you don't want to put in extensions? Is it drilling and tapping the spring perch or cost? If cost, I've got a guy making some for me out of UHMW-PE at a very reasonable cost. He is getting ready to offer them for sale. PM me if you want his contact info once you know the lengths you need.
