    Heated o2 conversion wiring

    GM powered the HO2S off the same wire that powered the egr solenoid. It doesn't draw much power(400 milliamps iirc).

    2 door 2 wheel drive Tahoe, 20's?

    I'm looking at getting a set of 20's to go on my 2 door 2 wheel drive Tahoe. I'm going to drop it 2 inches in front with a set of React spindles and 3.5" in back with Belltech springs. I've been reading posts for 2 days and cannot find a definitive answer. I'm looking at the Vision 142-2983GB20...

    Belltech Spindles

    I did some looking and it looks like 3600 was for 88 only. Looked on rockauto and they list a different upper ball joint for 88 than they do other years, so it's probably a pitch difference in one of the tapered seats that is different.

    Is a Redhead worth the price?

    My redhead box lasted 18k miles when it failed sending metal through my whole steering system. Put it back together with a junkyard box I resealed and pulled my pump to reseal it so I could get the metal out of it, didn't pull my hydroboost, and ended up blowing up a pump from metal that was...

    Any difference between early and late 2WD frames?

    The idler arm changed from 92 to 93. 88-92 used the 2 bolt idler and idler arm bracket assembly where 93+ switched to the 3 bolt idler bracket assembly and separate idler arm. The 93+ style is much better IMHO. Not sure if the 88-92 will bolt up to a 93+.

    Flex fuel L31 using the 0411

    The only way I know to do flexfuel on a l31 is do a p59(green/blue plug) pcm swap and run an 05 operating system. 05 is the only year I know of where you can get a flexfuel tune and an l31 tune that are both the same operating system. I'm considering doing this myself. Unfortunately the 02...

    Lowering 2 door Tahoe

    I've got a 99 2 door 2 wheel drive Tahoe, I'm tired of the rake that GM put in these, and I'm looking to lower it 2/4 to level it out. I know most say I'll regret it and want to go lower, but I want to keep this one useable to tow some, and get in and out of rougher roads. I'm going to be doing...

    5 to 6 lug, wheel spacers?

    Thank you very much. That look but leveled is what I want for my Tahoe. Thinking of going with a 255/60r18 since that seems like a common size.

    5 to 6 lug, wheel spacers?

    Do you have a picture of yours? I'm trying to decide on tire size.

    5 to 6 lug, wheel spacers?

    I plan on doing the rear brakes like in this sticky. https://www.gmt400.com/threads/13-nbs-rear-disc-on-14-bolt-sf.1856/ I also plan on doing an LQ9/4L80E swap, so I'll already be doing driveline mods, but I knew about the 14 bolt using a 1350 where the 10 bolt uses an s44. Now to start...

    5 to 6 lug, wheel spacers?

    Thank you, that's the confirmation I was looking for. I also like the look of those rims, that's the set I want to run. I also want to run big brakes using off the shelf parts, and a 6 lug swap will make that possible. For the rear it's a set of spacers like shown here in this forum, and I've...

    5 to 6 lug, wheel spacers?

    That's what I'm doing. Up front I know it's just rotors. I located a c2500 6 lug rear, but then I'm stuck looking for 6 lug rims to work with the narrow 2 wheel drive rear axle. I can get the 4x4 9.5" axle easier and cheaper than the 4x2 version, and I like the look of the stock Chevy 18's. I...

    5 to 6 lug, wheel spacers?

    I searched and could not find a definitive answer to this. I have a 99 4x2 Tahoe that I plan on swapping a 14 bolt 9.5" SF under. I also want to use late model 18"GM wheels. From what I've found 5 lugs have 4.5" backspacing, but late model wheels are roughly 6" BS. If my math is correct, I will...

    GMT400 Speedometer Calibration

    1st I would look and see if they installed a speedometer correction box between the PCM and cluster. You can calibrate it via tuning, but some do it with a module that corrects the PCM's output so it gives the speedo the required pulses per mile. Wouldn't want you to spend the money on a tune...

    HOW TO: Fix Bouncy/Hummingbird Fuel Gauge Needle

    Depends on the year and engine. All diesels and gas models to 97 are a simple circuit where the reostat/sender pulled the gauges signal wire to ground to move the gauge. 98+ gassers went through the PCM for the fuel gauge. Hence why all the hummingbird fuel gauge needles are 98+ as you're seeing...

    Best alternator upgrade ?

    I put on a new Remy ad244($108 brand new) for a 05 silverado, and the heater tube hits the case.

    Best alternator upgrade ?

    Fyi, if you put an ad244 on a 5.7l vortec, you will have to do some finagling with the heater line that runs around the alternator and to the water pump. I just put one on mine and found I had to put a 1" spacer between the alternator bracket and the mounting tab for the heater tube to get it to...

    Factory Alarm Activated

    What factory alarm? You're dealing with an aftermarket add on. GM didn't put vats in a truck until 97, and even then it was just a passlock system.

    454 to Diesel Swap

    And where am I whining? It gets REAL old hearing people dog the old 6.5 when it isn't that bad an engine. I'm simply stating my opinion of them and replying to the comments directed at me.

    454 to Diesel Swap

    Yes, I now own a DURAMAX, I NEVER DENIED that. I have ALSO said NUMEROUS times I wished I would have left the 6.5L in it instead of swapping after seeing what peopel have done with them recently. I have seen the shortcomings of the GMT-400's frame with high torque as I'm putting more down than...

    A/C Issues

    Pressures with the A/C off out in the sun can hit over 150 if it's baking in the sunlight. Hooked my gauges up the other day when it was 95 degrees, truck parked in the shade, but it was up to temp as I had just driven it about 5 minutes before(inside wasn't cool though), and it was around 125...

    Brake conversion?

    SSBC makes a dual piston caliper that is a direct fit for the 6 lug trucks. HANG ON TO YOUR WALLET THOUGH! The sad part is, I did the math, and they actually have LESS piston surface area than the 3.15" 2500/3500 SRW calipers do.

    Engine too old to Chip?

    You will find you get VERY biased 6.5L info here. The 6.5 bashing here is worse than most FORD forums I've been on. Yes you can chip it, but I would save your money and do other mods 1st. Do things like upgrade the cooling system to the balanced spin on fan clutch water pump, make sure all the...
