Question about 2016 honda rubicon deluxe suspension

I recently bought a 2016 Honda deluxe rubicon with the IRS, it’s getting close to hunting season so I’ll need to stiffen up the suspension since I’ll be carrying heavy loads at times…. My question is, if I adjust the rear, will I need to adjust the front also ??? And if leave them stiff, will it cause it to wear out quicker ?? Thank you for your help.
