3.73 gears

slightly... it might even hurt your et's if you dont have traction. My POS bolt on fox (3.73s) doesnt get traction till top of 2nd if i hit off the line (from idle). So if you were barely hooking up with the 3.55s you really arent gonna hook with a steeper gear. But, if your on dr's or slicks or really sticky street tires you should see an improvement.
