Wanted3.73s but so many horror stories about mechanics not installing gears properly kept me from pulling the trigger. Then I hear that you should also upgrade to Trac-Lock at the same time. Then I found this: all inclusive, factory-built, nothing to put together, pretty much a 100% bolt on solution. Worries be gone! I've had it on for a couple months now and it's nothing but a joy. Only down side is my mileage went down because I'm always playing in 3rd and 4th gear! HAHA
