4.10s?
Hey guys! I've been looking for a cheap upgrade recently since I'm getting married. I have a guy who does all my work for me, so install price isn't a big deal. I've always heard that if I go FI that 4.10's aren't the way to go. I also already have 3.55's.
What brand should I go with? Also, do I need anything else besides the ring and pinion and where are the cheapest places to get them. Thanks!

go ahead and get the FRPP ones, 3.73s will not provide a noticeable difference, so 4.10s is the way to go, especially since you are a 5 speed. Also, seeing as you're getting married, I guess it's safe to say there will be no power adder for you any time soon, so 4.10s once again will make you're car feel like it gained 50rwhp. What's you're mileage? If you're over 30,000 miles, I would recommend you also get a rebuild kit.

I did mine recently and went from the stock 3:55 to a Ford Racing 4:10 gear set. I recommend the Ford Racing gears because in most cases like mine you can just transfer the pinion shim over and reuse the stock carrier shims. I had a perfect tooth pattern and backlash. No noise no problems. I have 17k miles so I just stuck with the original carrier bearings and only replaced the pinion bearings both inner and outer. Only reason I replaced those is that I bent the inner bearing while pressing it off the pinion to get to the shim. Get a new crush sleeve, pinion shaft seal and locking nut. If you have a higher mileage car you may be just as well to get a master install kit with all the bearings, seals etc.
You will definitely notice a difference in low end torque off the line and interstate driving is a breeze. The 4:10 belongs in the car IMO period. You'll read it's one of the best low cost mods to do to increase the fun factor.
