Yes extra drop may go beyond capacity of tie rods ends. More drop increases force trying to bend those as well. They you negotiate obstacles. CVs pop out of front hub stripping snap ring sometimes, lets dirt in. Some CV actually grenaded when off roading being pushed beyond their working angle. 1" is actually is borderline limit what front end can handle. Smaller spacers < 3/4" seem to fair better. Even then you risk damage. If you plan to play around town and don't mind potential damage it's ok mod but if you like expedition style trave. I would stay with stock suspension. And please get bigger bolts to secure those at least M10 instead of stock M8.
