2001 4wd...

 

My truck has 3:73 gears,, and I am kicking around going to 4:10 gearsets...

 

Anyone that has done this swap, where in the heck would you get the ring and pinion?? The GMParts direct site shows them, but they are super crazy... Anyone use aftermarket stuff?? Where did you get them??

 

Thanks

I went 373 to 456 for the 35 in tires I had. They were Motive Gears. Bought on ebay. 2 gear sets with install kits for 479 shipped.

Yukon has gears and lockers..

 

I'm with them though, the difference in 3.73 to 4.10's wont be too significant to justify the change, if your going to lift the truck(or if it is) and put on bigger tires i'd go 4.30 or 4.56's or higher depending on tire sizes.

I've installed 285 75 16 tires on my truck, which it'll have that size of tire until I scrap it...

 

I was just weighing the options of regearing my truck( only has 120K miles on it), versus the search for a 4:10 geared used truck in the future...

 

So going from 3:73 to 4:10 isn't gonna provide that much of an improvement?

Your tires are not much bigger then mine, and I can still light mine up.. You;d be better off spending 250-300$ on a tune and getting the exhaust sounding right, the tune will make it pull like it should, and the exhaust.. eh I like rumbles :lol:

but yea, having a shop do it i'd suspect after gears and labor atleast 650-900$ if not more.. can get a tune and exhaust for under 600 easy.

I second the tune and exhaust. Get some Blackbear under the hood of that thing and it'll shift like it should. Then take all the money you saved and get beer.

I've thought about getting a blackbear tune, but I am timid because I don't want to kill my tranny.. Gears are a post tranny add, and that is why I was thinking about it..

 

I am ashamed to say that I have a hypertec tune in it now(hey, I got the tuner for 70 bucks offa ebay), but I have pondered getting the scan cable and getting a custom tune...

 

 

My truck has 120K miles on it,,, I am not dogging my truck, I tow some(boat, ATV,ect),, so, would everyone be comfy throwing a 93 octane tune in a 9 year old truck with those miles??

 

Exhaust wise,, you guys suggesting a new muffler??? I'm not gonna go the headder route, due to the cost, the install, and the underhood heat that headders give off..

I had 3.42s in mine and bumped em up to 3.73s. I am pretty happy with the jump in torque but I don't tow much. Threw in an Eaton LSD in at the same time. Total with labour was 1400 CDN. Put a vette servo in, chirps into 2nd. I'm on the throttle quite a bit (unless going to work) and work far away so 4.10s weren't a mpg wise choice. RPMS at 60mph are 1800 up from 1600 with the 3.42s. Blackbear tune tomorrow so we shall see.

You're already killing it. The great knowledge on this board has given evidence time and time again on how and why a Blackbear tune may actually prolong the life of a transmission.

I honestly think my tranny will live a long and useful life, but if it die's tomorrow,, I will remove it and rebuilt it myself.. Before when I had a 4l60 die, I didn't have two other vehicles to drive, so I paid to have it repaired.... So when/if my tranny ever dies, I'll trailer it to work and remove and rebuild it there..

 

Anyone done the cable scan tune?? If you go that route, you don't have to send your PCM off, do you?? They e--mail you the tune and use the cable to install?? Or did I dream this?

Mmm.. I don't have 93 octane here, but i'd recomend it.. i went 89 cause it's the same $ as 87 here.. and as far as the tune.. it's worth it.. I just did a custom mail-order with core replacement.. It increases tranny line pressue and the truck shifts so much smoother, 18k on my tune so far and the tranny fluids just as pink as she was when i put it in, and I don't have any tq nannies or anything else.. thats the main reason i love my tune.

 

As far as the exhaust, Cat back system for a tune is fine, gets a more fine tuned sound and free's up some of the bends usually.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Here's a starter kit:    CC Jensen, a Danish oil testing Concern gives us the following guidelines:   ISO 14/12/10 Very Clean Oil ISO 16/14/11 Clean Oil ISO 17/15/12 Lightly Contaminated ISO 19/17/14 New Oil ISO 22/20/17 Very Contaminated and not suitable for any service.   In addition CC Jensen gives a table showing how engine life is increased by cleaning up the oil. For example cleaning the oil from 19/17/14 to 13/11/8 will extend motor life by a factor of 6X.   But even cleaning it two “Life Extension Classes” will double motor life. So perhaps giving those classes would be useful:   21/19/16 20/18/15 19/17/14 18/16/13 17/15/12 16/14/11 15/13/10 14/12/9 13/11/8   *************************************   https://testoil.com/program-management/setting-iso-cleanliness-targets/   Third paragraph from the bottom will give a starting point.    Your next question should be, okay 10um at what Beta ratio and the answer is in the graph Beta 75.   Then the next question is what is your chosen filters profile? (Purolator PL series below) The red dot is Beta 75. This was the information I obtained from MANN a few years ago. So the best filters, Purolator One, AMSOIL EA, FRAM Ultra, Royal Purple, Bosch Premium should get a doubling engine life over filters like Purolator L, any service filter from any quick lube, WIX, NAPA, STP, Mobil 1, Purolator BOSS.    And as noted by CC Jensen a 2-5 micron @ Beta 200 bypass system has the capability of a six fold improvement. AMSOIL has such a system as does Donaldson.       Now having said all that testing is the touchstone. Test the oil NEW and test it with your chosen filter. Then test over milage. Do the work, get the result. But understand this in NOT absolute BECAUSE this is one factor in isolation.   Example:    A valve spring supplier can state that with cam X and a valve train of Y grams the valves will not float to 7K rpm. is that true if the builder choose a system 20 grams over limit? Common sense must be used and limits understood.

      This doesn't look like a GM truck. Not needed on a HD truck

      It varies a ton around me. Some places are still at $5.00 or higher and others are way down into the $4's.   Offroad diesel was $4.02 at the one station I passed today.

      2027 Chevrolet Silverado: Official Discussion

      By Hdwrguy · Posted

      So after reading the reveal from Chevrolet, I kept asking myself...why did the trim levels change?   Here are the official ones:   Work Truck (WT): The quintessential fleet truck, built with durable, easy-to-clean interiors for commercial or utilitarian use. Custom: A stylish, road-oriented trim that adds a more refined appearance, standard dual exhaust, and modern exterior styling. Custom Trail Boss: An entry-level off-roader featuring a 2-inch factory suspension lift and 34-inch mud-terrain tires on a budget. Silverado: Serving as the new base consumer truck (replacing the previous LT trim), it comes standard with the Z71 off-road package when equipped with 4WD. Trail Boss: Steps up the off-road hardware with the 2-inch lift, 34-inch tires, monotube shocks, an exclusive off-road hood, and more premium interior options. ZR2: The flagship off-roader. It boasts 35-inch mud-terrain tires, Multimatic DSSV dampers, front and rear electronic lockers, forged carbon-fiber interior accents, and an available hardcore Bison Edition (co-developed with AEV). High Country: The pinnacle of luxury. It replaces bright chrome with modern satin chrome, 22-inch wheels, premium leather, real wood interior trim, a panoramic sunroof, and an exclusive front-passenger touchscreen. As others have stated, why would you want a Silverado - 'Silverado' - wth?? LT needs to remain!!!   Also, there will no longer be a dedicated Z71 model.  All 4x4 trucks will have the Z71 package. Carplay is also something that cannot be removed.  Hopefully it will remain.     I am excited about the 5.7L V8 (350 C.I.D.)  Old school Chevy power.  My only concern is whatever version of AFM/DFM cylinder deactivation.  Too bad that isn't an option a buyer can choose to have or not.   I will definitely be stopping by my local dealership when these trucks start showing up.
