    6" suspension rebuild

    I got a 96 Yukon 4x4 and am in need of a 6" suspension rebuild. Anyone got a full parts list including bushing kit already installed where I won't have to go to a machine shop? Any good brands people have used before that don't exactly blow the bank, but have a history of good durability? Sent...

    Do you guys run out of Florida? Is there anyway possible I could shit the ECU to your location to have the modification done? Sent from my iPad using Tapatalk ---------- Post added at 10:53 AM ---------- Previous post was at 10:53 AM ---------- *ship. Sent from my iPad using Tapatalk

    Black Bear Performance Tune, Orlando Area, FL, Oct. 4-5, 2014

    I have a 1996 GMC Yukon SLT 5.7L. How much does it usually run to modify the ECU to be set for "35 tires, 4:56 gears, cold air intake, by providing optimal MPG? Sent from my iPad using Tapatalk ---------- Post added at 09:18 AM ---------- Previous post was at 09:17 AM ---------- Also catless...

    LS edit?

    I have a 1996 GMC Yukon SLT 2-door 5.7L. Has anyone ever heard of sending in their computer into a company named LS edit or directly to GM to have the computer tuned to what's been changed with the vehicle. Such as, catless exhaust, 35" tires, and 3:56 gears in the rear and have the computer...

    Cats r cut off. How to create dummy o2 sensor.

    I'm gonna try cleaning out the MAF first along with a non fouler to start. Injectors are super expensive for me right now. Those other two options are well worth giving a try. I appreciate the help man. Sent from my iPad using Tapatalk - now Free

    Chevy/GMC differentials

    What kind of things you got in mind? Ultimately I want to take stress off the engine and drivetrain, while at the same time seeing if there's anything I could do at all to increase MPG's. I would think 4.56 with a power programmer may get it back up to stock MPG's at 12 mpg. Sent from my iPad...

    Chevy/GMC differentials

    Oh yeah, that's the beast. I don't have whole lot done to it at all. Just the 6" lift on 35's. I got a cold air intake on it, but my buddy and I feel like that may be apart of the problem. Sent from my iPad using Tapatalk - now Free

    Chevy/GMC differentials

    I appreciate the help man. Let me first say that I know little to nothing when it comes to this sort of thing, but I would think that 4.56 gears would really kill what little mpg I already got going. As far as the front end goes, I was gonna wait till a little later on due to lack of funds. I...

    Chevy/GMC differentials

    I'm trying to find either a 3.73 or 4.10 gear ratio rear differential out of a Chevy or gmc model out of a junk yard that would be compatible with a 1996 GMC Yukon SLT. Anyone know which models those might have come in?

    Wheel speed sensor out.

    Recently I have had the Chevrolet dealership diagnose the reason for my abs light being on. Turns out the wheel speed sensors are bad. I have noticed break performance issues. Nothing serious being that I did a full on break job about 4 months ago replacing everything. I don't think it's...

    Cats r cut off. How to create dummy o2 sensor.

    I have my cats coletely cut out, and I've heard rumors that there might be a way to trick the o2 sensor into making it believe everything is normal to keep the engine from running so rich. I always have to wait a bit when I first start up the truck for it to run somewhat smoother. If it's not...

    Gear ratio suggestion

    I have a 1996 GMC Yukon SLT sitting on 35/12.5/15's and I was wondering if replacing the stock gears with a 4.56 gear ratio would make the gas mileage worse. Sent from my iPad using Tapatalk - now Free
