NORCAL SS

So you know the trailblazer ss airbags fit inside the rear 15 up gm suvs and even those make the back of the truck ride better. I have tested the tbss bags replacing the oem springs in a 15 and set at oe height it would still shake and once lowered down the airbag the shake is gone 3 inch drop. Once again proving that pinion angle change and vehicle height is the issue

you have a liner spring stock. gm didnt make a progressive rate. its not only changing the springs its also the fact that yoru changing the pinion angle as well as how the truck pushes air. for the guys that are keeping stock height your stuck. GM wont fix your trucks and the way the truck was built and being up so high is a issue. my local dealership had 1 of my customers in for weeks at a time. vibrating and ear issues. Did my lowering kit on it (1.5/3 drop which isnt much) and he had no more issues with his. the dealership knows me because of my cars and called me and was like tony what did you do? unfortunitly lowering wont be for everyone. I understand that but i pretty much have more feedback to fix the problem then all these people bringing their trucks to gm for what over a year now.

Sorry to hear that. I also level just the rear to front and customers have no issues. This community is fighting to get results and overall gm messed up. Unfortunately lowering the truck is the fix I'm seeing and the people who want to keep the trucks up high..... there's no fix. I'll keep posting my customers trucks that I do and give results.... so hopefully gm can "get a clue" linear springs are hurting this truck. Leveled rear to front guys like also

I use drop spindles nothing changed in front on springs or shocks. Rear oem shocks with shock extenders and just change to progressive lowering spring

Pinion angle change along with spring change to progressive and overall height of the truck coming down is the combination which helps. On top of that truck hanukes much better

Pic for reference

Lowered another yukon. Just like others I've done vibrating issues customer stated are gone. Like I told my service rep here the truck stock design is causing issues. Once lowered the problems are pretty much gone in this case. Ive lowered over 60 new gm suvs with great results

No sorry.

yes factory is a linear spring. here is another truck i just finished up. leveled rear ride/cornering much better.

No I have a 2011 escalade and 2016 escalade..... and 2016 z06 and 2013 ctsv and 96 impala ss with 33k miles. I love my gm vehicles

Never have had any of my customers have issues wuth 4wd on my 2/3-4 kit going to tahoe Leveled another 15 tahoe today. Vibration she stated is gone. Progressive rate springs are working. 64 year old lady also happy she can get in easier. Another tahoe travelers truck I did. Nnbs but same deal no probs going to tahoe. http://www.tahoeyukonforum.com/threads/come-along-with-norcal-ss-on-a-lowering-escapade-on-a-2011-tahoe.73989/

just like the other 07-14 with autoride if you go onto tahoeyukonforum people running my custom kits agree rides better then oem. I will keep everyone updated as I go on and do more trucks. POTHOLES like crazy in san francisco I have no issues driving mine on 26s. If you want a tire with more sidewall you can do a 24x10 with 30mm offset and a 305 35 24.

not true. Many of my 15 up customers go with my 2/3-4 drop kit and no issues going from northern california ie bay area to lake tahoe which is 220 miles. Snow up there has not been a issue also. I also am doing the road racing event for the good guys coming up in my escalade. Thing corners like on rails now. OH also the 26 inch rims/tires are lighter than stock 26s 88.6 pounds here is the oem 22s with tires 90.6 pounds 5 user(s) are reading this topic here is the 2/3-4 kit which has more than enough level for snow. best of all handles and rides better then stock. GM needs to address the height issue.. but by doing that lots of people will have trucks that will need to be at least 1.5 inches lower in front and 3 in rear

no they do not the vibration is almost gone. One even went to the dealer and they confirmed it with the tool they put inside the truck and stewart chevrolet sent this into gm since gm wanted to see readings. The rear of these trucks sit much higher then previous generations. Also gm lengthened the rear lower control arms so there are difference. I lowered a lot of these trucks current and previous generation. Some customers say they have no vibration while others notice it and after lowering they said the noise pressure is gone while the vibration is barly noticeable its actually pretty drastic. My truck is slammed to the fullest and I have NO vibration at all. The trucks where they siad its almost gone are only at the 4.5 option of my drop kit so me being 1.5 lower just tells me its a airflow turbulence issue. The truck handle SO MUCH better also when lowered its just a win situation. Mine is a 3/6 drop also on my truck i did front/rear swaybars along with shorter endlinks both front and rear MAJORRRR difference. Now we know gm wont lower these rigs but so far ALL THE THINGS THEY HAVE TRIED failed and I feel the design these trucks have is the killer. Well at least those customers that lower them will be happy stock front links vs the new ones i install in customers trucks. Swaybar angle fixed and better cornering since bar is no parallel with ground rear helper bags on these trucks!! tows much better heres one i did oh yah rear swaybar upgrade/endlinks and greaseable bushings stock bar left vs bigger bar right

lowered a few of these rigs so far including my 2016 escalade. my customers said it help a lot with vibration. I have a feeling the stock stance of these suvs causes air turbulance around vehicles at stock ride height which is amplified inside. my escalade WWW.ESKYOWNERS.COM
