Just curious what you guys have seen in gains from going to a 4.10 gear from a 3.55.

Right now my truck went 12.27 with the hoosier slicks with my stock 3.55 gears. Thats no juice and hot from the street and no traction bars and the 6 rib blower belt. HEHEHEHEHE It was also like 95 degree's with 90% humidity that day.

I'm hoping that with a 4.10 gear and all the above fixed and compensated for I should go 11's with no juice. What do you guys think?

Tommy from TRZ racing is going to put a motive gear in my truck for 550 bucks with the gear and all other parts included. Not bad, I think. What have some of you payed?

 

Considering I just saw a price on 4.10 gears and installation kit for 555.00 +shipping, your deal looks good to me.

BTW, your pictures look great. What kind of camera do you use?

I'm back. I just found Strange 4.10 gears for 400.00 shims etc. included. 15.00 for shipping.

I don't know what a typical install labor costs.

I'm gonna try to get the bucks together to do a 4.10 in mine. I asked all these questions a while back. Lot's of pros and cons. Seems that most that have done the change, don't want to go back.

I would do the 4.10's if you are gonna keep the 20's. I to have the stock 3.55's in my truck i was told that the 20's knock it down to like a 3.06. The 4.10's will bring it to about a 3.60 with the 20's. Thats my next major mod to the truck.

 

with the tall hoosiers you will see gains with the 4.10's. If you use anything shorter then 28" you WILL hurt your times.

In my case earlier in the year, I cool weather with the e/t streets, I ran 13.00-13.15. I switched to the taller hoosiers in hot and humid weather with the exact same mods as before and ran 12.60-12.70s.

You will burn the **** out of your street tires and forget about launching on them.

P.s. I paid too much form 4.10's. Your deal looks really good.

 

i dont have 1/4 mile times but seat of the but test say it was a lot faster.50 to 100 is a thrill and the heck with traction down low cause when it hooks your gone.

 

Hey RT, the 4.10's plus the upcoming cooler Fall air will definately put you into the high 11's, get your cage ready, John H.

 

RT Killa- I was thinking of switiching to 4.10's myself. Most people that actually have swiched to 4.10's love them even for every day driving. The problem on the street they say is traction which should be a problem for me because I run Nitto 555R's all the time.

The cheapest place that I found for a quailty ring and pinion set with an installation set was Reider Racing. There 4.10 Percision get set and installation kit is $385.00.

My only question is how much performance increase will I see from the 4.10's with 28" tall tires?

 

Well with all that said it sounds like I am getting a pretty good deal.

Tommy is a distributor for motive gears so he gets them for cost for me and then just charges me for install.

If any of you guys in the area want to have it doen to yours, he's more then willing. And I know he can do it cause tommy has built some of the fastest pro 5.0 cars around along with some crazy outlaw and renegade cars.

let me know guys cause I'm doing it!!!!!!!!!!!!

 

Personally, I'm not a big fan of gears in these trucks. Our trucks make peak torque between 2000-2500 rpms. If you've got a stock converter, then gears may help, but if you've got an aftermarket converter, then you are already launching right around peak torque, and the gears will spin the motor out of that range faster.

Since we are moving lots of weight, and fighting the wind at the same time, it's more important to use what torque we have accelerate the truck for most of the track, and then let the hp take over above 4800 rpms. Go with too steep a gear, and you are out of the torque range too early.

Back in 99, I remember guys putting in 4.10s and 3000 stall converters, and going SLOWER because they were launching the trucks 1000 rpm past the peak torque area.

I usually suggest people stick with the stock gears, for whichever year they have, unless they do mostly 1/8 mile racing where 3rd gear isn't much of a concern. Or if your truck is mostly street driven, gears can make it more fun.

In our own trucks, we left the stock 3.55s in our 99, and back then our 99 test truck 60fted better then any truck with different gears, even nitrous trucks. In our 01 test truck, we actually took the 3.73s out, and put 3.55s in, and went to a 30" tire, giving us a 3.30 rear ratio. The reason for this is because the rpms were way to high in 3rd gear. With the 3.73s and a 26 or 28 inch tire, we were hitting 6000 rpms by the 1000 ft. With the 3.30 setup, we go through the traps right at 6000.

 

Ok so what do you think I should do then sal? Just leave the 3.55 with the hoosier slicks?

 

Well, I don't want you to do something that you don't want to Joe, but I'd suggest 3.73s for your truck. That will basically bring you back to the same rpms as with the 3.55s and 26"s.

 

So just them then, thats cool. I trust you more then any one else sal, so thats what I'm going to do then.

do you have any of those gears for me?


by the way, how did you like the PSP sticker I got?

 

Sal, I mainly just run my truck on the street and occassionaly at the track (Which is an 1/8 mile track). I run 28" tall Nitto 555R's year round. Do you think I would be better off with 3.73's or 4.10's? Would it even be worth while to change to 3.73's? The difference between the 3.55's and 4.10's by my caculations is
346 rpms. I also run a 75hp NX shot as well. Any suggestions?

 

I don't have any gears for you. I would have given you my old 3.73s, but they got damaged on removal for the 3.55s. And the sticker is spiffy .

 

Well, if you plan to run on Nittos, I'd stick with the 3.55s. The Nittos work good from the contact patch and the sticky compound, but they have no sidewall absorbtion like a slick. So going to a steeper gear, is going to shock that radial harder, and you'll most likely wind up with worse 60fts instead of better, especially on the spray.
