I really want to. My mom’s not a big fan due to the already limited room we have at the house, but it’s a pretty cool truck and I’m hoping seeing it tomorrow confirms that

Don’t know if this is the right thread for this, but tomorrow I’m gonna look at this suburban to see if the guy wants to trade for my 96. It’s a little rough, but it’ll be a toy, and I’ve always been a big fan of the old squarebody burbs.

I took a couple of pics of the 3" rear coil spacers and adjustable panhard bar from Supreme Suspensions that I installed a while back. I guess when you go up over 2" in the rear it can mess with the lateral movement of the tires/wheels. Mine were sticking out about an inch or so further on the passenger side. The adjustable panhard bar put it back to normal.

I swapped in Z71 springs and 2" spacers, kept the factory bar, and I don't think the driver's and passenger sides are different by even 1/4". Like you, I swapped out the sway bar links, I used ones for a 3" lifted Jeep Wrangler.
Glad to see you zip-tied the E-brake cable, as opposed to letting it dangle free. Zip ties kept breaking with mine, I finally used some 2" wide Gorilla duct tape, and wrapped about 8 layers over the cable and bar. Has been holding up for over a year:happy107:.

Cars that can be started from your phone already exist. My wife's Mazda CX5 had the option available. Brothers GL63 has phone start too.
I know theres aftermarket kits that allow this but didn't know factory was doing it. Nice.
My cousin has the viper remote start with his smart phone.

got my wide band installed. was raining hard just as i finished up installing it, as i was looking for a dead fuse under the hood key off. ( got wet) skirted the few rain showers i had during install, at least it was over 40º.

missed the paint color by a few shades, good news is it matches the lighter trim in the truck so its not 100% awful.

im not one to fully trash things, like drilling a large hole in the A pillar, so i ground a hole on the bottom back side and ran them in the open a few inches. not like you can really see em.

and on top of all that. i added a load of fuel to get the ltft in a normal area, i was showing +6 at idle and driving around, added to the maf and got it to -3 idle and driving around, wb pic there is at idle, showing 14. 6 to 8 aka perfect, and wot is at 12.4 ish also perfect. and that was from me just adding a splash of fuel and commanding the pe mode to be at, yup 12.2. f ing nailed it again without a wb. but in the end guessing is not best, you really need to know what your AFR is in real time.

once it gets nice out again im off to add some more timing now that i know the fuel is more then safe. truck already has woken the hell up a lot. timing should really be a topper. being im 100% knock free right now, had some knock when it was still a stock tune. aka there that lean BS tune for ya.

New drive belt won't fit. Tad bit smaller than the original but everything says this is supposed to work. is anybody aware of a hack like heating up the belt before you try to route it on there? Only problem is it takes too long to get the belt into position; it would be back to air temp when I finally got to the tensioner.

Part number is correct so all I can do is spend more money to return it then buy a different make. Seems like a lot of trouble for something fairly insignificant, right? I got too good of a deal on this piece to now start jumping through hoops but in my experience bargains come back to bite me in the a$$

I bought a replacement belt for my 03, just because it was old. I already had replaced my alt for a higher amp and everything was good. Well, the replacement, which the book said will fit, didn't. It was a hair too short. I had to bring my old belt to compare the size. I had to go 2 sizes bigger. Sometimes these trucks are just oddballs I guess. Did you compare it to your old belt?

The higher amp alt likely has a larger pulley to increase alt output at idle. Sometimes this requires a bigger belt. Ive installed overdrive alt pulleys and been lucky enough to have the belts fit though.

That's exactly the belt I put on my '04 5.3L with the 145 amp alternator (RPO KG3), except the belt I picked up had the newer Continental Elite labeling.

Is there a number on the belt, and does it match the sleeve number? Any numbers on the old belt?

From what I read, the 145A alternator takes the belt number on the sleeve (93 inches), but the 105A alternator takes a shorter one (~92.2 in.), 4060922. Maybe a mixup in packaging?

Not sure if they offered a bigger alternator or if yours could have been upgraded.

The higher amp alt would most likely have a smaller pulley

Why would a lower amp alt have a shorter belt then?

EDIT: the answer is that the alternator case is smaller for the 105a alternator. Even though the pulley diameter is larger (at 2.3") than the 145a alternator (at 2.2"), the distance between the mounting point and the pulley center is shorter. Hence a shorter belt is needed.

This in no way answers the question as to why the Gatorback belt doesn't fit @Chubbs's engine.
