2nd Gen Non-Engine/Transmission Changing rear gears

[NIsaacs]

Didn't, he switched from 4.10's to 3.54's! SNOKING

I think he was asking JR why he was interested in the 4.10's.

OH! Anyone that tows with a second gen auto should have 4.10'S, unless one has no mountains and wind in sight!
With 265 tires and 4.10's I tow at 62-63 MPH at 2000 RPM's which is the sweet spot from the over valved 5.9! At around 20K+ combined I get 12-13 MPG.

I changed my 98 12V from the 3:55's to 3:73's. It did perform better but 4:10's would have been better. I was trying to compromise since I did so much commuting with the truck at that time.

 

[JR]

Not to be nosy or get in your business but why do you want 4.10 gears ?

3.55s are way too tall of a gear for moderate to heavy towing. Im also running taller tires so it compounds the issue. I have enough power to tow what I need but if I could find a good deal on a set of lower gears I would be on them in a minute. If I was to buy new I would opt for 3.73 or even 3.90 but I would never recover the cost, hence why I keep an eye open for a cheap set of used gears.

I had 285 tires and I thought 342 gears on my 01 I could do 80 at 2150 I pulled heavy and would usually get 12 to13 mpg as well so maybe the lower gears numerically don't help as much as I thought I just Hate running the at over 2200 no matter what I'm doing .

 

[JR]

At that rpm you likely had 3.55s.

Why do you not like running over 2200 rpm?

 

[cadet38th]

could you swap the dually rear end from a 2001 with disk breaks into a 1997 dually that had drum brakes without any problem?

 

[JMcCoy]

I went from 3.55 to 4.10 and am very happy with my decision. The 3.55s were way too tall with 35" tires. Fuel mileage has suffered some. I'm hoping to gain some back when I bump up my timing.

I have a set of 4.10 gears for a dana 80 and the limited slip carrier if you need it. Let me know if you are interested and I can send some pictures.

For anyone who is looking for gears I suggest you find the part number and enter it into a google search. The set I found was a brand new set from Yukon for 250 bucks plus free shipping on Amazon of all places. Every other site I could find had the same gears listed at over 600.

The prices can go up and down fast. I went back to the ad I used a few days later to post it here, and the price had gone up by 100 bucks. By the way, USA Standard Gear is made in India.

It's been well documented that Amazon moves the price up and down based on your viewing history. If you view ANY item and go back in two days the price will be higher by 10 - 20% (or more). If you wait a few weeks the price will be back at the original. Or use a completely different computer.

If you haven't blocked ads on your browser then Amazon will also serve ads of stuff you've looked at on other web sites. Go to Amazon and search for "camo panties" and see how often panty ads show up on other sites.

Don't know where you picked up that little nugget of info, but it doesn't work like that. I've had over 100K items listed and sold THOUSANDS of items on Amazon since 2011 for the company I work for. Prices are set by the individual seller, not AMAZON. Mine is set up with a software program with a minimum price per item calculated from my cost, shipping, and Amazon fees, then it compares my price to other sellers and adjusts it accordingly. With 100K items listed, my program "crawls" each item and adjusts the price every 3 days. All items are the same price to all buyers, no "viewing history" voodoo magic.

Amazon is the seller in most cases and engages in dynamic pricing. As an example, I was researching HVAC relays ($36). A few weeks later I went back to Amazon and they were $70. A couple of days later they were $40. I like researching my purchases so I've noticed how the price changes from day to day.

They're not the only ones. Many online retailers tweak the price from person to person and day to day.

I just don't like running that high to many years driving truck and tractors I guess .
