Bilsteins (186735's) on the front of my 2009 SUT-replaced worn out OEM. As noted everywhere else--glad I did, big difference.

 

Picked her up from the hospital. She came home with a brand new engine and ported heads. My next task is to get rid of any and all chrome.

 

Had 4:88 gears and full length headers installed ��

 

Why the gears? Larger tires, towing, etc?

Same question on the gears. Did you have to reprogram?

I know for my 2008 I had to reprogram when I went to 4.56's. I was told by several installers that the car goes in limp mode if you don't reprogram. So I made sure I had the programmer in the car when I dropped it off for the install.

 

I have a 6" lift with 40" tires...it's was a dog ...couldn't get out of its own way...already blew one transmission didn't want to blow another one...yes I have a programmer that allows you to set gear ratios and tire sizes...with the gears and headers it has a lot more power again and the transmission isn't hunting for the sweet spot all the time...it's like a new truck!

 

Yes I have a programmer...it allows you to pick gear ratios and tire sizes...you can also select shift points/shift firmness etc...

 

Glad you pleased with the headers - breathes a lot easier on the highway right !

 

Hey #instagram buddy! Yes I love the headers...wish I did them a long time ago..truck sounds mean and definitely has more power...too bad I did gears at same time. Abuse I can't honestly say which mod was better...regardless love the difference!
