    Replacement shocks

    Actually Bilsteins have a digressive type damping system and damping is not dependant on distance the internal piston travels. At low piston speed the shock is stiff which helps with body roll, dive, and squat. At high piston speed the damping force is pretty much constant which is great for...

    Replacement shocks

    On another forum, a member switched from Z71 to the HDs and the HDs were more stiff. Based on threads it seems like the 5100s are pretty plush. ------------------- Edit: The 5100s and HDs (4600s) are basically the same regarding dampening qualities (Bilstein website). Also just read...

    Icon Leveling Kit

    Icon coilovers are awesome. I have not seen any used on this site. I will be putting the Icon 2.5s on my FJ.

    Trimming for 285/65/18 tires with 2.5" Level Kit

    They are Nitto Trail Grapplers and have about 40k miles on them. Could probably get another 5k, but will assess how they do this winter. I would buy them again, but this is now my wife's rig. Next set of tires might be Nitto Terras or Goodyear Duratracks. Trying to get better mpgs... FYI...

    Trimming for 285/65/18 tires with 2.5" Level Kit

    I thought about it but I actually take mine offroad and would hate to have all that dirt and mud in there. Also if you take them out the corners might get floppy - never tried it though.

    Has anyone tried to tie in Airlift 1000 into autoride?

    Good to know. I have never needed more than 30 psi.

    Has anyone tried to tie in Airlift 1000 into autoride?

    Keep in mind the max psi for the Airlift 1000s is 35 psi. Not sure what the OE setup is rated for.

    Lifts and clearing tires

    ^ IMO do not put a spacer on that lift. I would think the CV angles would be too much. Gonzo and another member are running 35s, but they have the 4-inch Rancho lift.

    Squeaky Z71 bumper

    Mine does not squeak. Is there a way to add some foam then retighten the fake skid plate? Keep in mind that I have never taken that part off.

    HD hood on a Yukon questions

    Are you talking about NBS or NNBS? I recall for NBS it is a straight replacement. For NNBS it would take some work... I would love to have an HD on mine. Any pics from those that have done that on an NNBS?

    Couple of mods.....now no power

    These are just my opinions from a standpoint of designing piping systems for vapor extraction and pressurized air applications. The increase in piping may help out at high rpm (higher flows), but will not at lower rpm (apparant loss of torque at low rpms). IMO it s more of an effect on exhaust...

    Couple of mods.....now no power

    IMO 3-inch diameter piping is too large for the 5.3L. Yes it does not sound like much of any increase, but the frictional losses are exponential regarding changes in diameter. The flow is now turbulent (versus laminar) and now the exhaust velocity decreases which reduces exhaust scavenging. A...

    Couple of mods.....now no power

    What is the size of the new exhaust piping? What is the configuration - dual, single, x-pipe, etc. Which Magnaflow muffler?

    Anyone running an Air Lift 1000 kit on the rear of a '07+ Denali??

    I don't have the auto-level system, but wanted to let you know Airlift 1000s work well. I installed mine in 2009 and they are still working great. Just make sure you keep at least 5 psi in the bags to keep them inflated and in place. Good luck and hopefully you can use them.

    Gear ratio question

    Towing and safe transmission temperature?

    These are the temps I see also, but we have a lot of hills around here and the ambient temps in the summer are around 100F. However, I have the 5.3L and 4L60E tranny. Looking to upgrade the tranny cooler though.

    Trailing Arm Relocation Brackets for Rear Level?

    Can't comment on the trailing arms for the Tahoe setup, but you are right regarding the rear shocks. Longer travel rear shocks, like Bilstein 5100s, will provide more flex than OE length. Not really a fan of shock extenders though.

    I know, I know I am beating a dead horse!

    Here's a link showing Blackbear intake dyno results. As others have mentioned, performance gain is from the tune. http://www.tahoeyukonforum.com/forum/showthread.php?t=41254

    2007 Z71 Tahoe leveled

    Both are good, IMO depends on your use. The Trails will be better in the mud and DuraTrac is better on the street. You are down south, but if you drive in the snow/ice the DuraTracs are the way to go.

    How do I make my 2007 Tahoe 4x4 ride better on washboard roads?

    I believe the 5125s are just universal fit versions of the 5100s. IMO it would be better to get the 5100 because they would be valved specifically for the Tahoe. You guys are right though, a custom tuned spring and associated shock would be optimal. Good luck and keep us updated.

    7.5 inch Rough Country 2007 Tahoe (PICS)

    I did the chalk test and I am running ~ 50 psi. Had the dealer adjust the high pressure alarms so the warning lights would not be on all the time. Looks good. Like others have said, keep an eye on the CVs.
