    calling all suspension and rim/tire experts

    Start with the cheap stuff first. Rotate tires, new wheels or not it takes one harsh bump to bend a wheel. A bent wheel doesn't vibrate all the time. The right front wheel on my wife's Yukon is bent. At 25...no vibration. 35,45,55,65 no vibration. After that yes. I've just been too busy to...

    Where to spend my $$$$

    Shorties aren't worth it turbocharged because they don't retain as much heat as cast iron manifolds. Unless you have to run tubular headers for clearance or fitment replacing the manifolds is a mistake. That's why STS systems have everything wrapped as they want the heat and exhaust gas...

    04 denali mods??

    There's a B&B exhaust on performancetrucks.net for 450 shipping BNIB which would bolt run on your truck and be 1000 times nicer than Gibson. CAI I would get headers and a tune first. Bigger gains there IMO

    TR224 cam?

    Zippy wasn't running a 228. He did 5.3 heads 863 castings I believe on a LQ4 with a TR224. I think a 224 would be too big in a Suburban. Especially in a 5.3. To say it is a race car cam and doesn't work well in trucks is laughable. Look on pt.net that cam is almost as popular there as round...

    04 denali mods??

    4.8 5.3 and 6.0 are all interchangeable. Only difference is your exhaust won't have a Y off the headers. You will have 2 parallel pipes all the way to the muffler. If you have a good exhaust shop near by I'd get headers and have them connect your stock exhaust to the collectors of the new...

    Have 3.73...is it worth going to 4.10? or higher?

    Prime example of the observations that led to my sig. Now, what I've seen is usually an increase from 3.73 to 4.11 would roughly be an increase in gearing advantage of .4 which usually translates to an increase in cruise RPM of around 400. That isn't exact but will ball park you. In my...

    Helix Throttle Body Spacer?

    Unless you get about 5 of them, cut a hole through the hood, at run a velocity stack type K&N or bird catcher it's a waste.

    3/5 drop - not quite

    If the front is sitting higher than the back you can adjust it with the torsion bars. What rear coils did you use? They will need to settle

    Found new problems with AC resistors....possible fire hazard

    This weekend on my Chevrolet 3500 my AC suddenly stopped working. I took the panel off and checked the harness....came back on. While I was starting to put everything back together I noticed the smell of burning wires and started to see smoke. I pulled the wiring harness off, pulled the resistor...

    Replace Liftgate Fuse.....WTF

    I have read lots on the net, made a post on here and didn't get much feedback....hopefully I will get some help because it annoys the HELL out of me. First part of 2009 I took my wife's Yukon which was an SLE and took all the interior, wiring harness, and stuff out of a SLT and swapped into our...

    Problem with AC stopping blowing cold until restart

    I did actually replace both the blower motor and the resistor today. On blower speeds 4 and 5 it would make alot of noise. The reason I replaced the resistor was because on my 3500 this weekend it went out and the wiring harness started to overheat and began to melt. I never knew this was a...

    First hand experience with lowering Sub and Yukon XL

    Illegal Regal if you read my first post it says what I've used and what I got to work. Again the feedback I've received has been from Tahoe and Yukon owners. If you go back and read my post I said that what works on those doesn't work on Subs and XLs in my experience. I have 0 respect now for...

    Problem with AC stopping blowing cold until restart

    My wife's Yukon while driving down the road will stop blowing cold. You have to turn the truck off and then restart it. What could it be?

    Should I pick up an LS6 cam or something else?

    He said on there dyno that they baseline 230. I don't put much in dyno numbers, just use them as a barometer of what I should expect. All dynos read different.

    Should I pick up an LS6 cam or something else?

    Dynajet? Is that different than a Dynojet? I am not sure what they use but I would imagine they have a Dynojet. I wouldn't say the number are that high for a 5.3 with worked heads, headers, exhaust, electric fans, a cam of 219/230, and a tune. I had a 6.0 with similar mods without a cam that...

    6.0L mods?

    Manifolds are not that good, I would do a tune, electric fans, corvette servos, headers, swap the muffler out for a dual inlet single outlet muffler and it should run pretty good. If you are planning 24s and etc I would do FI instead of a cam as most cams (that the average person thinks they...

    Patriot Performance GM LS Series 5.3 L Head and Cam Kits

    232/230 on a 110LSA......what the hell are you building something to sound like a pro stock car and have a powerband of about 1000 rpm? The biggest I would do would be something like a TR224 on a 114 with a 3000 stall and 3.73 gears on a 29" tires. If I don't turbo my wife's truck I am going to...

    VMAX street tuned.

    Is it just the 367hp swapped motor with a tune? What other mods?

    Should I pick up an LS6 cam or something else?

    I called Thunder Racing today and asked them about the 5.3 in my wife's truck and they suggested some of their cheater cams. The V3 for me. I'm torn between a head and cam setup or running a small 214/210 cam I have and getting a turbo setup. Just fyi they said that cam in a 5.3 with shortie...

    First hand experience with lowering Sub and Yukon XL

    Tony my point was what Modded said. I obviously wanted something that rode better than what I had used in the past and the Belltech had the most first hand positive feedback. I wanted my wife's truck lowered but my thought was ride and comfort first the drop second. Everything I saw about the...
