    Transmission question

    Thanks for the fast response guys So as long as it had the 6.0 it should be 4L65? Is there any identifying marks or numbers on the case to determine what I'm buying? For some reason I was thinking the 03-06 transmission was different than the others.

    Transmission question

    So my 2003 Yukon Denali XL finally started having transmission problems. It's made it to 230,000 miles. In my past searching i think i read that there was a difference in the transmissions that would work as a replacement but i can't find it again. Or am i wrong? I found a few transmissions...

    I wish there was a way I could get a X-pipe in there and turn the exhaust out before the rear wheels on both sides but the fuel tank is in the way. I'm trying to avoid your typical truck sound if that makes any sense. The popping/clapping sound. I thought it was because the pipes were so long...

    I did away with the factory catback and had a local muffler shop put in a MagnaFlow. I'm not happy with it at all so I will probably just replace everything when I install the headers

    Are you refering to it not being a Y pipe? Where it's 2 pipes that go in to the muffler? Or is there something else different?

    I may just go ahead pick up some of that wrap. I'm hoping that there isn't to many clearance issues, otherwise I may not be able to wrap them without really having to crush the tubes. Thanks for recommending that. Did you all have any issues with clearance or installing them?

    Yeah I just saw those headers from speed engineering. But they are sold out, and they told me it would be closer to the second half of July before that get any more in. I wanted to get the 1 7/8 primaries because I'm building a 408 to put in my Denali and would like to stick a magnacharger on...

    So I was looking for a set of longtube headers and off-road Y pipe to install on my 2003 Yukon Denali. I was wanting to go with a set that has the 1 7/8 primaries, and with my searching I found that there was a few companies like calspeed, lpp, and pacesetter. I also saw that there would be...

    Z06 Calipers

    I was wanting to do the Z06 caliper swap on my 2003 Yukon Denali XL. And I'm running a set of U2-55 wheels in a 24x10 with a 30 offset. I can't find out if these wheels will clear the Z06 calipers or not. Do any of you guys know if it will work or not?

    My Denali has 227,000 miles on it right now. I plan to build a 408 to put in it, have the heads cnc ported, a decent cam and a stall converter. Don't want to get carried away because this is my daily and I do occasionally tow with it. I have 2 project cars I'm about finished with. A 1994...

    My Build Thread

    I got burned out messing with my other car projects and thought I should mess with my Denali a little bit. So a few months ago my Denali developed a upper end knock and I wasn't really sure what it was. To me it doesn't sound like a lifter tick but more like a wrist pin. Anyway I just wanted to...

    Lowering my 2003 Denali XL

    Thats what I'm wanting. I love how that truck looks. I guess I should have included this originally but I do occasionally tow with my Denali (boat & car trailer). Would that still be ok to do with that small of a sidewall? I was originally going to get 26's but wanted more sidewall. Do you mind...

    Lowering my 2003 Denali XL

    Hey guys, I have a 2003 Denali XL that I'm getting ready to lower. I have already purchased the 3/6 drop and adjustable panhard bar from Tony. I'd really like to be at 4 or 5 in the front. I know that there are a few options to get it lower but what would you guys suggest? Also I have got a set...

    Nothing to major. Still have a few more things I'd like to do in the spring like a big brake kit, headers, intake, tune and I'm going to upgrade the sound system a little bit.

    Nothing exciting but I do have a few updates. I sold the led tail lights that were in the truck when I got it and put the stock ones in until I decide on a set I want. Thinking about doing the all red with clear on the bottom. I bought a 3/6 drop from NorCalSS and I'mpretty excited about that...
