I think the new OME shocks are a bigger diameter than the stock shocks so will be closer to your tire.
Yes the easiest way to fix this is to use a wheel spacer to move your wheel further away from the shocks.
The standard wheel offset is 50.8mm
If you are keeping the same tire size maybe a 1/2 inch spacer or 1 inch spacer is all you require to move the tire away from the shock to stop it touching.
Or if you want you could get a new set of wheels with a 30mm or so offset to step your wheel out further away from your shocks
You dont mention what height lift you have 2" 3" 4" ?
If you plan on running a larger tire that is wider than standard you will need a bigger spacer or new wheels with more offset.
I think the biggest spacer is 2 inch. ( generally in sizes of 3/4", 1/2", 1", 1.25", 1.5" and 2") but they are availdable in all sizes if you search.
If you have lifted your jeep its center of gravity is higher which could lead to increased risk of rollover When cornering.
Using spacers or a wheel with more offset will widen your stance and reduce the risk of rollover when cornering.
The offset you need depends on the width of tire you want to run
I have ran the following with no problems
235 wide tire with 10mm spacer or offset of 40mm
265 wide tire with 30mm spacer or offset of 20mm
305 wide tire with new wheels offset of 10mm
The easiest way to work out what size spacer or offset you need is to start with standard of 50mm, choose the tire size you want and choose a spacer or wheel with an offset to move your wheel out enough for the tire not to touch.
Hope this helps
