There's a lot of aftermarket specialty choices. Depends if you want a stiffer ride or softer ride. Most retail auto centers will have several choices for either stock OEM replacement or a heavier, more sporty option. Some if not most shops will give some kind of window, 2 weeks or 30 days, etc for you to determine if you like the new shocks, ie- their ride guarantee.
Just keep in mind that when you put on any new shocks the vehicle will feel different immediately. As we drive our vehicles, the ride quality diminishes gradually over time and we tend not to notice. Just give whatever shocks you decide to go with a few days of driving to get used to instead of going back for a refund. Same goes with new tires and front end repairs. When suspension or front end components are replaced, all the sloppiness that you was there when you drove into the shop with is not there when you drive out. People always freak out about that for some reason. Lol.
That being said, most shops will stock Monroe or Gabriel which are fine for straight OEM. Rancho will give you a stiffer feel and is marketed for off road performance. Being you have a 99 you may have Bilstien's on there. Check out RockAuto for an idea on selection.
