stay away from spacers! if you get deavers for the rear it should be real close to being even. save your money for a wider housing for the rear. currie, g machine racing, blitzkrieg motorsports, giant motorsports, ruffstuff specialties, camburg, dirt tech, threat motorsports, 9inch floater. all the web sites i can think of right now.you still need the guts for inside the housing. 9inch floater sells complete axles for around 800 bucks. whatever width you want. never used them befor but, seems like the best bang for your buck option.....
