It's no wonder why every American owners LX is fast and beefed up! I just called my local ford stealership, a set of factory 3.73 gears... For a whopping $589.90!!! These guys are higher then ten hippies! So then I went on summits website, the same gears for street/strip 3.73's for a stock 8.8 rear end for a $159.00. We take it dry with no lube here that's a fact!
