On my LX notch I am looking to get some gears. Not because I need to lose even more traction, it is that my 2.73s are killing me. Gas wise it would help to. I plan on sniping some 3.55s, but what else do I need. Like a Ford Racing Trak-lok rebuild, or what? It would help because I really want to get this done soon.

Well, first let's make sure that you picked the gears that best suite your car. What kind of motor mods do you have? What transmission do you have? What kind of driving do you do?

If you are going w/ 3.55's you cant really go wrong. You could possibly go with a steeper gears but its not like your going to high. If you have a manual (which I am assuming) 3.55's are decent gears for street/strip car thats on the highway a decent amount of time. But you could go bigger though if you wanted with no problem.

When you have the gears installed, I would definetly look into Ford Racings Installation kit. I believe they make three different ones and the one that you would want cost around $90 dollars.

Also, rebuilding your Trac-Loc is definetly not a bad idea but it will cost you some dough. The FRPP Trac-Lok rebuild kit is only $40 dollars but when I called the shop they wanted an extra $200 dollars just to install that kit (not including gears or installation kit... just trac-lok kit).

So all together if you do the gears, trac-lok rebuild kit & gears installation kit:


Gears: $200
FRPP Installation Kit: $90
Trac-Lok Rebuild Kit: $40
Gear Installation: Est. $250
Trac-Lok Installation: Est. $200

Total: $780 plus new speedo gear (like $10 bucks) and also gear oil & friction modifier ($5)

You do not HAVE to rebuild the trac-lok but it isnt a bad idea to do it while your already in there tearing the rear apart. I am getting gears installed soon but I am NOT having mine rebuild just for the simple fact of the cost... but my trac-lok is fine... for now.

Good Luck!

3.55s are a good gear ratio. It really doesnt matter what you have done to the engine or any of that they will just help over the 2.73s.
If its an auto car I might think about some 3.73s, but your honestly not going to see a big difference between 3.55s and the 3.73s

Not really, but I don't think you'll be dissapointed with 3.73s... For the kind of money that you're suggesting, I'ld amost double it and be happy with a 9"...

post a poll and i bet most guys will suggest 3.73's ...remember to get the $10 speedo gear

Well, personally if you are keeping it NA and automatic I would go w/ 4.10's and manual 3.73's (if also NA)

88BlueGT..are you serious? $200 for the damn track lok installed?

that sounds like a rip off to me since its like right there when they're changing the gears

gear calc fingure out what suits you best, also i would upgrade to a detroit true trac

as far as fuel consumption goes, go with the 3.55's they are a good all around gear
3.73's are a little hard on gas, i know b/c i have 'em
