That happening all the time means accelerated wear on shocks = you're looking at buying new shocks anyway.
Replace shocks/struts at the same time is cheaper in the long run. You spend less labor getting them installed at once and the shocks last. And you have your OEM shocks sitting around so if anything goes wrong with your aftermarket setup, you can swap 'em back.
Learn something new everyday. And glad to know I mad the right decision when I went with the kit instead of just the springs.
