Been awhile, finally have all parts to change out rear ends (wheels/rims 81to 83mags, 19/17 to 18/16's). For those and any one else, it was said the changing would raise my RPM some, would using an 83 rear differential instead of the 81 help bring down the RPM's?? I've been told in past it's been told gearing in gearbox was the only way to lower RPM! Just needed some more clarification before I make the change :wave: !!
