Depends how much you want it to come up. I'd say get Bilstein adjustable struts if the price is right. They work well in other applications... Not a big fan of spacers. I'm assuming it uses struts.
Spacers will work ok then. You'll lose some up travel obviously. Probably not enough to make a difference. I've got 1.5" on my xj and no noticeable ride difference. My xj still hits bumps on harsher bumps.
