You're right, quicker is the word I should have used. Much quicker. I'm running 275's all around, so rubber on the road isn't a problem. And the reason I start off in second most of the time is not because it spins, it doesn't. The rpm's just go so high so fast in first, that in most situations it's pointless. My girlfriend drove it down the street when I first got it, she said it scared her how quick it got up and went. And like I say, I LOVE that part, but I'm not a racer anyway. Plus, I have a Z28 that I can use when I need to get that out of my system.

You know...I could be wrong on what ratios the Hypertech will correct. Maybe it's only 3.42 and 3.73. I sold mine so I can't check it to see for sure and I can't find details on Hypertech's web site. The HPP III's manual is there as a .pdf, but it doesn't specify what ratios the unit will correct.

No car originally with 3.23s but now equipped with 4.10s is going to be "very fast" or "faster". In fact, top speed is significantly reduced with the 4.10 axle over the 3.23. What the car will be is quicker, but (and a big "but") it will get quicker, only, if it has the traction to use the lower ratio and if you have to start in second gear, you totally don't have the traction. My guess is with a mod'ed engine (say 230-250 hp) to actually have the car go quicker with 4.10s, you're going to need more rubber on the ground in the rear and a limited slip differential. If you don't have that, any improvement in acceleration time is probably imaginary.

thank you mister know it all. In fact the car will be faster. faster and quicker are the same word http://thesaurus.reference.com/browse/faster
changing the gear ratio will make the top speed lower, but most people dont try to reach 125mph on a daily basis.

you can calculate using those formulas to find out any missing variable. IE. to figure out RPM at a certain MPH.

IF he has 275/40/17's then at 70 mph he will be running at 3767rmps. this is also given that 5th gear has a final drive ratio of 1:1, and not an overdrive.

Marty,
What are your goals for the car? Does it have the LSD in conjunction with the 4.11's? The 3.23's are great gears IMHO and to me, a great driving experience is a whole lot more than what the car can do for a few seconds in a straight line. However, I'm not going to tell someone with a different gear ratio that they should conform to my standards. If the car is fun for them that's all that matters.

When I first bought my car from Carmax (a place I will never go to again) I had to have the entire rear axle replaced because it leaked at the seam between the carrier housing and the axle tube. While they did give me a warranty on it, they installed one containing the wrong gear ratio (2.73's along with a series 2 carrier) which I had no knowledge of until I opened it up to mod it. About a year later (after warranty had expired) I moved to a place with a lot of hills that the car simply would not climb when it got wet out so I decided to upgrade to an LSD. I looked up which gear ratio I was supposed to have on the door (code was for 3.23 gears) and ordered the appropriate carrier. It wasn't until I had cracked the rear end open and swapped the ring gear over that I found out it wouldn't fit back in (since the series 2 ring gear is thicker). Since I already had the bearings pressed on to the LSD and the ABS ring installed I couldn't return it so I decided to take the car to a rear end shop and have the 3.23's put back in. Carmax's service department wouldn't return any of my calls and corporate even failed to respond to my complaint so I sucked it up and footed the bill. After all the parts were purchased and I paid for the labor to set it up, I probably spent money that could have been used to purchase a complete 12 bolt rear or something a bit more durable.

The point to this whole story is to know what you are getting into with this project. Know what parts you are going to need (if you don't know do not assume, especially since you know the rear has been modified from stock) and then weigh the costs of what the parts and labor will cost you versus what it may cost you to purchase an entire rear differential that has already been set up the way you want it.

What the hell? Sell your rear and buy a stock one. You can find one on craigslist for 50 bucks. I see them free on some sites. You can even get a 3.42 gear with a little taller tire.

That thing should sell quick. Or if you ever wanna race or go "faster/quicker" keep that mofo.

I have a 5 speed and 4.10, Im calibrated for 3.73 and a 25 inch tire. When i moved to 4.10 i also ran a 28" tall tire. So my speedo is perfect and I have alot more rubber on the road.

Since you've never done a burnout, whats the price on the rear?

Re: anybody know what rear end gears are standard on a 2001 5 speed?

I would love to get 4.10/4.11's installed someday. I also think that the the top speed would actually increase. Sure, the theoretical top speed would be reduced, but there is no way our cars would ever get to 170 mph or whatever the top speed would be at redline anyway. However, if the real-life top speed is about 140, I'll bet that going from 3.42's (mine w/ an auto) to 4.10's may allow it to get up to 150 or so, or maybe even higher. I had my speed limiter removed. From what I read here, though, HP Tuners is the only option. I was hoping a cheap HPP3 would work for gear changes, but I guess not. The dealer is no help either. They can only program for factory-offered gear options.

putting in lower gears will let the car get to its top speed faster, but it has no affect on speed what so ever, your cars rpm limit and torque does.

you can put 0.05 gears in your car, and if it has enough power it can get to 150mph, it will just take about a year and 5000 miles to do it.

with 3.42 you may be going 150mph at 5500rpm, but with 4.11's you may be going 130mph at 5500rpm, or 150mph at 6500rpm (these are just estimated numbers)

i agree with him, if you just want a stock gears im sure you would have no problems finding a whole rear end and then selling the one you have for a couple hundred bucks

Be careful when buying a used differential. Sometimes they come out of cars that have hit a curb or had severe rear end impact causing one or both axle shafts to bend. The axle doesn't have to be folded in half to be bent, either. Even if the hub is a couple degrees off true, it will cause the rear caliper to vibrate back and forth on the slide pins and make a nice chirping noise once the pins lose their grease.

Some people I know will replace the rear end in the car if the pinion bearing starts making noise instead of just having the bearing replaced. Thankfully none of these people I know have deceptively tried to pawn off the defective one to make a quick buck but I am sure those people are out there.

I'm not saying all used rear ends are bad, and I am not saying you cannot find a good deal. Just be careful and know what to look for if you choose to go this route. I'd hate to see you invest money in something that ends up costing you more down the road.

You can also look for 10 bolts out of trucks, S10's , GMC's I have a 10 bolt out of a truck in mine.
