hi. i got 3" lowering blocks in the back of my 00 blazer but i need it another inch, so i was gonna get 4" ones. i found ones online that are angled on one side asnd was wonderin if i should get those. i lowered it last year, and everyone has been telling me about pinions or something or how they had to do stuff to their driveshafts, but i never had a problem.i do electronics so im not good with suspensions. was just wonderin if the angled ones are better than the regular ones. here is the link http://store.gaugemagazine.com/index.asp?PageAction=VIEWPROD&ProdID=251

get the ones from summit 40 bucks i think, they are the same ones i use they have a steel shim and are angled for the pinion angle, the only thing u have to do is flip the brake line so it doesnt rub on the frame. ive ran them for almost a year now and drag raced with them and no problems.
