    Think of the rear end gear in your truck like a bicycle. 4.10 gear being 1st gear on a 3 speed bike. 3.73 being 2nd and 3.42 being 3rd.

    It is a whole lot easier starting your bicycle in first gear. You can get it moving alot easier and get it going faster with little effort from your legs. The same thing with the 4.10 gears. You can get the truck moving faster and easier with the "taller" gear off the line.

    The 3.73's, or 2nd gear on the bicycle, takes a little more effort to get the vehicle moving. You can't get off the line as fast.

    The 3.42's, like 3rd gear, takes even more power to move and even slower off the line.

    Once you are moving though, the "lower" gear (3.42) gives slightly better fuel economy. One of the reasons is that the engine is turning less RPM's with the 3.42's opposed to the "taller" gears.

    For comparison, all the trucks have the same transmission. At a given speed, 65MPH, the 3.42's will turn less RPM's than the 3.73's, which will turn less RPM's than the 4.10's.

    Hilly terrain also comes into play. The 3.42's may have to shift out of OD to maintain 65MPH on steep hills. The 3.73's or the 4.10's may not have to since they are turning slightly more RPM's.

    Gears also affect top speed. You can only pedal a bike so fast in 1st gear. Once you get it moving though, you can go much faster in 3rd gear than 1st. More top speed. The same with the gears.

    The 3.42's will give a slightly higher top speed than the 3.73's, and the 3.73's will give a slightly higher top speed than the 4.10's.

    So if you are pushing the redline and turning 6000 RPM's, you will be going faster with the 3.42's. Not much, but technically faster. (although GM has so thoughtfully put a 97 MPH governor on their trucks, so top speed really doesn't matter, ohhh, but there is the HPIII).

    For everyday driving, the 3.42's are fine. If you plan on towing a boat, camper, etc. the 3.73's may be a better choice. I do not know of very many people who have opted for the 4.10's.

    Maybe only for constant towing of a 5th wheel or 28 foot boat.

    You're electronically limited to 97 mph with any of the gears, 3.42, 3.73, 4.10. And the 4.10 doesn't give you more power, just more more torque

    3.73 means 3.73 to 1 gear ratio - in other words the engine needs to turn your drive shaft around 3.73 times in order to make your wheels spin around 1 time. With the 4.1 your drive shaft must turn around 4.1 times to turn your wheels 1 time.

    Have about 180 miles on the new trck. Is there a break in period? I have tried to keep it under 65 to this point but seem to be pissing a lot of people off on the highways. Here I thought by going slower they would be able to get a better look at the Pro Tec box, but they seem 2 b in 2 much of a hurry to get somewhere 2 care!
  • morin2morin2 Member Posts: 399
    Its in the owner's manual - I think 500 miles (mine is out in the barn & its getting cold & windy & its dark out there....). Not just a top speed limit - its probably more important to vary your speed (no cruise control, no towing, etc.).

    How do I remove a govenor for a '01 Rado 4.3?
  • obyoneobyone Member Posts: 7,841
    Buy a Hypertech Power Programmer III. You should also check the speed rating of your current tires. Don't want to exceed their capabilities.

    it's the engine. That's all it's got!
    I'm sorry, that wasn't nice.

    Tim im not clear on "Ryan starts out in 2nd all the time?"

    What does that mean?

    Oh yea truck is getting worked on today and tomorrow. Dropped it off this morning. Sucks not having a vehicle.

    i would appreciate knowing difference between Z83 and Z85 heavy duty suspension. does the Z85 suspension make a harder ride or is there any noticable difference in ride? also what is diff between silverado model CK15753 and K15753

    thank you
  • seeligseelig Member Posts: 590
    what Tim means is that you don't start out in 1st gear.
  • mledtjemledtje Member Posts: 1,123
    Z85 Heavy Duty suspension is just HD shocks. I got it on both my Silverado 1500 4x4 and my Silverado 2500 4x4.

    My advice is to save your money and buy Bilstein's after you get your truck.

    Coming up on 27k miles on my 99 silverado ext cab 1500and was wondering about how long the pads last on average.I assume fronts would go first but with the four wheel disc I'm not sure. This would be under mostly no load non trailering conditions. Any experience with this? thanx
  • quadrunner500quadrunner500 Member Posts: 2,721
    If you're easy on them, possibly 100k miles. I had over 40,000 on my previous Silverado, a '99 1500 Z71. They were less than 1/2 worn. The pads have ceramic content for long life. When they do go, you'll probably need new rotors at that time. Ceramic pads are why your rims stay shiny, don't get corroded by thick brake dust like Tundra, Sequoia.
  • mgdvhmanmgdvhman Member Posts: 4,157
    I got one.....good place to get it is right here...LOL:

    gee Mike you were up late... no morning tee time?

    Now here's something I know a little about???

    Ceramic is actually used as part of the fiber composition, along with Kevlar, Roxal, and some iron fiber. The fiber has more to do with axial strength and not much for dusting. From what I gather the typical formulations for "ceramic" pads use less graphite and carbon/iron powders that contribute to dusting. BUT ALL PADS DUST! The "ceramic" formulations dust is lighter in color.

    The OE "assembly line" pads are manufactured by Akebono in Kentucky (Yeah it's a offshore HQ company). The "service" pads available at the parts dept counter are different! The AC Delco Durastop are manufactured by Raybestos and sorry to say guys, even though they are ceramic fiber base formulation, they dust the wheels! The aftermarket Raybestos "QS" and NAPA "Ceramix" (same pad, different box) dust even worse and black too! I would have taken a picture, but the truck was so filthy after my Buffalo trip I had to wash it. (was 60 degrees here Tue)

    Tom is right though as far as the life expectancy may go to 100k. Surely the rears will, as less wear from braking will occur here. When I changed out for trial of the new pads I noticed that there was only 0.040 worn off the fronts in 18k!

    BTW the most important thing to do to get good life from premium pads is take it easy for the first 200 to 500 miles. Anticipate stops sooner, use medium pedal pressure while applying the brakes, and let the friction gradually build up between the pads and rotors to stop the vehicle.
    (info is also in owners manual...you read it of course...snicker/hic!!...one ringy dingy...)

    I am still not satisfied with the overall braking performance of the truck, however. When I rotate tires again in a month, I intend to take the "ceramics" off and install some Raybestos Super Stop which are a carbon metallic fleet duty pad. (yeah I used to work for Bendix, why would I be using the others? cause Bendix don't have Metlok pads for our trucks...sheesh marketing!)

    I anticipate more dust and more wear, but also more aggressive stopping power. Guess I will be like Ryan, and wash my truck every day...at least the wheels. Will let you all know.

    Something that was puzzling was, the Bendix StopShop Hotline and other sources reported isolated incidences of the RR pad, only, wearing out in 20k to 30k miles. We were never able to pinpoint why or get much in the way of details, and the reports have ceased as of September last year.

    One last item re: "ceramic" pads...due to the shape characteristics of the fiber and it's synthetic nature, Wagner Brakes states that it is a carcinogen! GM is the only OEM that we were aware of that was using them for assembly line, and even they were backing away from them to some degree.

    Hope this helps

    "Guess I will be like Ryan and wash my truck every day...at least the wheels"

    haha i wish i could wash it everyday.

    I havent seen my truck in a day :(

    Ill snap some photos when i get it back (if they didnt wash it) to show you how FILTHY from salt it is.

    You cant even see the center caps on my rims there is so much salt on em.

    Oh yea i had my rear pads replaced at 17K. Remember that squeak i had matt? Well since i took the wheel off and filed some surface rust off the rotor no noise since.

  • blackmax200blackmax200 Member Posts: 255
    I noticed that the slot in the center of my rear OE pads was filled with brake "sludge" and occasionally would make noise. When I was out in Buffalo, now the "QS" (quiet stop) pads started making noise. Weather conditions: slushy rain and temp 35 degrees. I have noticed that the rotors will surface rust quickly, but the pads should scuff it off. I think that the removal of your calipers had more to do with freeing up the mechanism to make them work right and keep the rotors clean... guess you were washing your truck too much... haha

  • ryanbabryanbab Member Posts: 7,240
    yea right there is no such thing as washing it to much

    To darn cold right now to wash it and tonight/tomorrow am we are supposed to get 10" of snow :) WOOHOO

    Just hope i get my truck back so i can make some $$$$ shoveling snow
  • seeligseelig Member Posts: 590
    no tee time for 3 weeks......or at least till i'm finished with school job i've been working on.
    go to work a 4 a.m., but usually read the topics here. always interesting to see what everyone has to say in here. {;o)
  • blackmax200blackmax200 Member Posts: 255
    Take the grille guard off and get a blade! ;-)

    matthew
  • ryanbabryanbab Member Posts: 7,240
    Matt maybe one day but this yr it wouldnt have paid off

    Id love an atv with a blade. Do sidewalks much easier and would be legal unlike if i did it with my truck hehe

    I really like your shed. I will bet it is a popular place with your friends. A man can get a lot of quality work done in a place like that. Nice selection, but missing one of my favorites - Coors.

    Tim isn't that the stuff we used for washing the corian down?...........haha
    good luck on this one now!

    I agree, and it is Friday!!!

    So is it New Castle Browns for you too?
  • ryanbabryanbab Member Posts: 7,240
    well its nice to have it back. few problems

    1. ext cab door has a 2 ft long scratch (taking it back to have buffed out)

    2. one of he fender flare plastic screw things is missing (noticed when i got home)

    3. tailgate has white spots in the paint. Dont know what its from but its like little white specs That isnt that bad my tailgate has lots of scratches

    Only good thing the scratch and dent is gone and it looks awesome.
  • seeligseelig Member Posts: 590
    one of the truckers fav's.........you bet eric
  • seeligseelig Member Posts: 590
    was your truck in the paint shop? if so, the specks might be from polishing compunds.
  • rayt2rayt2 Member Posts: 1,208
    Ryan, I was gonna same the same thing that Selig did regarding white spots, but where the h... did the 2' scratch come from, somebody a little careless at the bodyshop walking by your truck, no biggy should buff out as you said.

    Matthew, So I take it the durability on disc pads has improved quite a bit over my last Rado, that one used to eat disc pads every 25k miles. If I get 50K I'll be happy cuz I am a little heavy on the brakes but then again good citizens need us volunteer fireman to get there sooner rather then later thus my brake wear issue. I did have to have front rotors turned by dealer once already because of a warped rotor problem.
    I must say though the antilocks seem to be too sensitve to the least little washbord or bump in the road while braking, that feature I don't like on this truck but gotta live with it.

    The '99 lease I turned in last Octeober had 52K miles and the brakes looked as if only half was used. There was a little over 1/4" left all the way around.

    Dano
  • ryanbabryanbab Member Posts: 7,240
    will they come out? I used my finger and wiped to see if it was a dust and nothing just left finger prints

    I used some turtle wax (blue stuff) i had i am out of zaino and the 2ft scratch is hardly noticable.

    Biggest thing i am pissed about now is the fender flare screw missing.
  • ryanbabryanbab Member Posts: 7,240
    i swear i will never buy another dark truck or dark vehicle
  • blackmax200blackmax200 Member Posts: 255
    Good luck on this one, buddy

    BWHAHAHAAHAHAHAHHAHAHAHA snicker snicker hic cough
  • ryanbabryanbab Member Posts: 7,240
    yea one used to hold my fender flare in
  • blackmax200blackmax200 Member Posts: 255
    if you had one of the pre 99 rados, I feel the brakes on those were horrible! I waited 'til GM fixed the brakes on those trucks before I gave up my 87 ElCamino.
    Not only did they EAT the front pads and give 120k miles on the rear shoes, but they didn't stop real good either.

    I have "played" with the ABS on my truck and with the exception of the "Dynamic Rear Proportioning" (uses the rear ABS valves to limit pressure to the rear brakes) I am quite impressed. The DRP is what I think you are refering to as being overly sensitive. Put about 300 lbs of weight in the back to the bed and see if that doesn't improve the situation. If so, it is telling that the back is too light and the DRP is working to keep the rear brakes from locking up when foing over washboard sections of road.

    10-12" tonight/tomorrow
  • quadrunner500quadrunner500 Member Posts: 2,721
    We already got that storm Ryan. Dumped up to 14 inches in places. Temp was -7 last night, +4 currently.

    Still did not need 4x4 to get around. Kelly Safari AWR tires LT255/85/16 work great in winter.
