4.10vs3.42

ok, my 96 z truck has 3.42's ... i never race over 60 mph and mostly at a stop light here in town so that is no over 50mph ... i hate being beat, and i want an edge over the *****s who think they are better than me ... which gears would be QUICKER up to about 50 mph? would 3.73's help any?

Re: 4.10vs3.42

there will be many opinions about which gears to use. i personally like 3.73s and 3.08s...yes 3.08s. but this is because when on the road, my driving is highway, 70mph+.

the lower you go (higher numerically) you will get better torque multiplication=acceleration. but this comes at the sacrifice of higher cruising rpms. but you have an overdrive trans...so no problem.

for your situation, i would go with the 4.11s.

Re: 4.10vs3.42

Why are you street racing in a pick-up?

Re: 4.10vs3.42

its not any kind of organized racing, just when someone pulls up next to you and they think they are faster, we rev em up, light turns green and its pedal to the metal...not racing for money, just pride...
p.s. raced a 00 mustang (not a gt) friday night and won up to about 40 mph...thats why i street race in a pickup

Re: 4.10vs3.42


Is the truck 2x4? or 4x4? If it's 4x, you gotta change both sets. If you don't, kiss your transfer case goodbye when you forget you didn't, and shift into 4x4. On the other end, I would go to 3.73. At 70mph in overdrive, you should be at about 2000rpm. I think a 4.10 for a street truck is a little steep, and will kill mileage.

Re: 4.10vs3.42

What size tires do you have? If you have stock ones 3.73 would be best but its not really worth the money to go up one ratio so id say go with 4.11 so if you put bigger tires on it it will be better. just my .02

Re: 4.10vs3.42

Hey try leaving the hubs unlocked and put into low on tranfer case that might get you the extra boost you need. we used to race mud drages and thatsd what we did. Good luck it will make 6.84 Ps watch the red line

If it has tits or tires it will give you trouble.

Re: 4.10vs3.42

With a '96 I assume you have overdrive. You like to race I assume you have some decent meats on the back. Then I would go for the 4.11's. 3.73 will help, but 4.11 would be the ticket. 4.11 is 20% lower than 3.42, and 3.73 is only 9%. I run 4.56 with 33" BFG Mudders. I like them better than the 4.11's I had before.

I race my truck on the street every chance I get. Same deal, usually up to about 60 or so. I like my truck and horsepower so I made it both. I smoke cars everytime, I can 4X, and tow a trailer. Best vehicle I ever had.

Re: 4.10vs3.42

There aren't many vehicles that will stay with my truck to about 60 mph. I have 31" tires with 4.56 gears. I have a built 700r4 with a ratchet shifter. The best method is to drop the truck into second. Let the transmission make the first shift on it's own if you have a shift kit. Then whine second up as high as you possibly can. You will have most likely smoked your opponent by then. Then hit third and keep pulling. It is a killer set-up, but driving on the highway is a bit limited. Overdrive lets me go about 75mph at 3000.

Note, I am planning on going to 33's to get my highway ratio back. 4.56:1 could be too much for your application.

Sounds like a challenge to me. You ever go to Glamis? We could race there someday.
