  • I ordered my 2500 LT ex/cab LB, 8.1/alli Oct. 6.It's Scheduled to be built this week[Feb. 19]. Last year I ordered a 2500 GMC 1st week in Jan. Never did get it.
    It seems that the higher the volume of trucks the dealer sells the less trouble they have getting the special ordered ones. Next time I order one I'm going to check out the "big boys uptown" 1st. Also check out gmbuypower.com. You can click in any zip code and scan the inventory of all the dealers in that area. The waiting time not only depends on the dealers "pecking order" but also availability of options etc. wheels.com has good info. on factory holds etc. Last but not least take it with a grain of salt,if the dealer tells you 8 to 10 weeks. Most take 3-4 mo. Lots of luck.

  • Just a quick note to advise I replaced the black flares on my white HD with a new set of white flares from GM. Unlike previous models where the flares are attached to the inside of the fender, the flares in the 2001 HD attach with a handful of buttons and some double face tape. The flares were easy to change, the fit is excellent and the color match is perfect. Those of you who, like me, believe the black fares detract from the truck should consider replacing rather than painting. I'm very pleased. I have a set of new black flares for sale if anyone is interested.

    I also added a set of BFG All Terrain T/A's in 265/75. The new treads are approximately 1" taller than the 245's but I can't detect any difference in power. My tire dealer suggests the speedometer will be off by 2 miles per hour. Appearance alone is worth the investment. Also added a color matched hard tonneau cover and tinted windows.

    My GMC dealer informed me on Saturday that the White HD's are now coming with 'white wheel flares'. I won't know until April when mine should be here. Maybe you could get your money back.
    Why the bigger tires ? Is it to just fill the wheel well ?
    Wonder how a 8.1 would perform with headers ?

    1. Better tires than factory
    2. Longer lasting than factory.
    3. Better Wet and Snow traction
    4. Better off road traction
    5. Look Better
    6. Look like they were made for the vehicle
    7. A slightly higher overall OD ratio for improved milage with big motors.
    8. GROUND CLEARANCE!

  • Just got my 8.1 L 5sp Allison man this truck rocks.. If you like seat of the pants power buy the gas 8100. bad part about 11 mpg but it only has 300 miles on it.. 3.73 gear and massive Tq I love it CHEVYS rule.........
  • I agree with you, the black textured flares are butt ugly. They were the deciding factor in me ordering a black truck but I still don't like the cheap tacky look. Do you mind telling us what the shiny ones cost...... even though the color is the same I'm seriously considering switching.

    Or...... taking them off and going without. Is that a viable option or will the button holes look even worse?
  • Dealer list for a set of two flares is $171.73; wholesale (which I paid) is $145.71 and cost is $120.00. You can price out a set at www.gmpartsdirect.com. Part numbers for white are 12495834 and 12495835. Other colors are available. Without the flares the truck looks unfinished due to a lack of wheel mouldings. If you plan to remove the flares you may want to figure in the cost of mouldings.

    ordered my GMC 8.1 SLE ext cab LB 4wd last month.
    Got the snow plow prep package, but can't get an answer on what the beefier front suspension is rated at. Anyone know? Also, where are GMC's built? Hope to have mine in May.
    Thx........

    Ref Post 123, 127 & 128--

    My LT 8100/alli is in shipment and will probably be in around 26th to 28th.

    I have requested dealer to remove the 'Ugly Black Flairs' as soon as it gets in for the same reason you all have stated.

    Question on what the fender is shaped like when the flairs are REMOVED?????

    I have been looking at units without Flairs and I have ASSUMED that the fenders are standard shape for example like the 1500's.
    They have a nice 'formed into the metal die' flaired shape which doesn't look tacky and added on.
    Can you tell me if this is correct or what if not??
    Also where is the 'doulbe faced tape' atachment at exactly??
    I'm planning to just re-install the Black attachment Buttons back in the holes they came out of when the FLAIRS are removed. Will that work??

    I know there will me no molding now around the wheel well but neither do the 1500's as far as i can tell. Also on my older F150 that had chrome molding it was just a place for COROSSION to set in.

    Help anyone with advise on this because I probably wont see this thing while the flairs are being removed to change my mind.

    Thanks in advance-- 75v

    Hey Hunter98, did you have any rubbing or clearance issues with the 265's? I agree that for visual aesthetics alone, the larger tires pay for themselves, but are you experiencing any problems (clearance, short shifting or excessive RPM on the allison, or any thing else)? Thanks

  • I only glanced at my truck when my dealer was installing the flares. You are right that most of the newer GM don't have moldings. I thought the truck looked like it was missing something without the flares, which is what prompted my comment about needing moldings. I didn't watch my dealer install the flares, but the shop foreman told me they were simple to install and the process used double faced tape. You could always remove the ugly black flares, then add moldings or painted flares if the bare look didn't suit your taste.

    With regard to tires, my 265's fit without any changes to the rims, shifting, or clearance. If anyone wants to see what the flares, 265 tires, hard tonneau cover, tinted windows or Bed Rug look like, give me an address and I'll forward pictures.

    Folks:
    How is everyone making out? Are the aftermarket parts there yet for this bodystyle? I am looking for (when truck arrives) a bug guard, window vents, nerf bars...etc. Have all these parts surfaced yet? What about hypertech? Thanks for any replies.

  • Trying to get an idea of the difference in mileage between the 8.1 and the 6.0 (Extended cab, SB, 4X4, 3.73 gears, dry) any input would be appreciated.
  • n75v111n75v111 Posts: 243
    the same shape as what the 1500's look like (without flairs)???

    Have I made the correct assumption that they are??

    I just want to get back to the metal formed fender shape like the 1500's.

    Thks

  • I couldn't get the truck I ordered so went to the internet and found LT 2500HD truck like the one I had ordered except it has a 4.10 in place of the 3.73 and remote mirrors in place of the camper mirrors. Will be paying $500 over invoice. Truck will be in town tomorrow. Will be glad to get behind the wheel of that 8.1 w/allison. Will post MPG in the near future. Happy motoring to you. Dave
  • Sorry, but I can't help. I didn't pay enough attention to note shape of the fender openings when my flares were off. Good luck

    Surely you don't think Chevy or GM would short change you on the sheetmetal, do you? Like leave a big gaping hole in place of the plastic flares....

    Gents, any idea how I can learn when my PICK UP will be built. The dealer cant give me any more info than "the order has been received by the factory but not yet accepted" that is the standard answer I get from the GMC customer service center also. I ordered my 3500, 8100, Alli, 4x4, SLT Sept. 21, the order was received 10/10/00. Who would know if and when the PU will be built. Any help out there would be appreciated.
  • Are the premium wheels on constraint?

    Short change -- Naw!!

    Just was hoping some one had already 'Been Their/Done That' and would be able to say for certain.

    I'll find out in due time i guess!!

    Thanks
