So I've been on the fence between 373s and 410s for a while. The gears are most likely going to be installed within the next two months (I still want to pull the cover and inspect all the parts to make sure I wont need a new differential too, because there seems to be a lot of backlash). I have ***** Thumpr cams which wiped out a substantial amount of low end torque and I'd like to try to compensate with the gears. I like to go to the track so more mods and slicks are in the future so I'd like to make sure I make the right pick. PLEASE CONVINCE ME ONE WAY OR THE OTHER!!! Haha thanks in advance.

 

how much do you drive on the highway?

 

Ehh I do a fair amount of hwy driving. On AM's website it says there's only like a 300rpm difference at 75

 

Yeah the difference isn't that crazy. I've driven on one long trip with it on the highway and it didn't feel too off, just had that feeling like I was getting close to shifting into another gear to cruise. But I had torque available so I didn't have to downshift to pass.

 

No doubt. Honestly I'm leaning towards 410s but it's one of those things where you can't feel it out until you've spent $650. What were you tacing in 5th at 75?

 

I was focused on navigating so I didn't get to note exact rpms, but I know I was staying around in 2-3k at highway speeds

 

You have 410s right? Does it accelerate a lot faster under hard driving?

 

Yeah, I have 4.10s and I'm having my detroit locker installed as we speak to replace the Trak Lok I killed. I'll post feedback on the locker once I try it out.

The gears accelerate a lot quicker, and your RPMs will spin up faster. In spirited driving I found myself using the higher band so much more than with the stock 3.55's. It also kicks the tail out real easy when I give it throttle in a turn

 

Haha AWESOME man! That's what I want. It should be especially cool since I have 331s stock. I HATE them. They're soooooo weak. And I'm sure it puts more stress on the clutch too

 

Just think about this : =) : thats yur face after everytime you going wot after installing 4.1 gears

 

The thing that made up my mind was looking at reviews of 3.73 gears and 4.10 gears, there seemed to be many more people saying "I should have gotten 4.10's" than "I should have gotten 3.73's" but even more saying "I love my 4.10's!"

 

Ahhhh yes! That's awesome. I found a ford racing kit on eBay that comes with the gears, install kit, and a gt500 pinion bearing for like $225. Probably next month. So stoked =D

 

Let us know once they're installed...I'd love to hear your opinion on the difference. I definitely have seen many comments saying "I should've went with 4.10s".

 

Yea no doubt man. I do a lot of WOT type driving so you'll get a pretty honest opinion. I imagine the difference is gonna be pretty noticeable going from 331s to 410s =D
