I currently have the MAF 30mm spacers installed front and back, and am ready to order an OME 850/860 combo. My question is if anyone has this lift with spacers also, or is it best to just leave them out all around. Or maybe just run them up front. I have stock bumpers for now and I am running 285 Duratraks. Thanks in advance for any info, or links that would help out.
