2014+ Suspension Lifts

any chance you could get an overall height measurement on your truck to the top of the onstar antenna?

Measured mine this morning and it is 81" to top of the OnStar antenna.

After adding air in tires to 42psi the fender height is 45" in front and 45.25" in the rear.

Damn, you gained some height from filling those tires! What were they at before?!

Robert.jean1 · August 9, 2015

Installers put them at 31-32 psi.

I can't believe that 10 pounds of air increased the height by that much. Have you seen any stabilitrac issues surface yet?

Robert.jean1 · August 9, 2015

Who knows, and nothing problematic so far. I'll keep my fingers crossed. Also it is completely possible that when I measured it the first time I read it wrong but I know I didn't read it wrong this morning cause ya'll made me feel crazy so I went and checked again

Your truck looks wicked. Is there anything you had to do in order to use stock wheels cause even on the BDS website it states you need aftermarket rims with 5.75" back spacing. I really want to use my stock rims aswell.

Thanks

I went with the 6" BDS lift and thank you.

No nothing at all. Before I bought my kit I contacted BDS and asked them crap loads of questions about using my stock wheels. They assured me the best fit was gonna be the OEM wheels. And they were correct. They did tell me if I wanted to ensure my rear wheels stuck out the same as the front then I needed 1.5" wheel spacers. My fronts and rear are sticking out pretty much exactly the same.

Excellent thanks for the info, exactly what I wanted to hear. Any idea what your OEM wheels offset and Backspacing are?

Would these fit my truck without rubbing?

20x9 Black Fuel Maverick 6x135 & 6x5.5 +20 Wheels Terra Grappler 285/50R20

I have RC 2.5 front and 1" block rear.

Robert.jean1 · August 10, 2015

I say yes but am wondering why you would choose a smaller tire than stock

Didn't know that size was smaller than stock. What is your recommendation?

Robert.jean1 · August 10, 2015

I would suggest looking through the leveling kit thread. There are SO many great examples of member's trucks. Also a way that helped me research what tires I wanted on mine was

http://tire-size-conversion.com/tire-size-calculator/

The sight helped me out immensely. Before I lifted my truck I had a RC 2.5" level and was thinking about a 285/60r20 as that is a 33.5" tire.

Thanks for measuring. I'm still nervous. That gives me 1/2" of clearance under my garge opening.... !

Robert.jean1 · August 10, 2015

Valid. Also you gotta remember that it also depends on your tire size and brand. For example my 35" MT are not really a 35" tire more like a 34.5" tire and it varies across manufacturers.

Make sure you check manufacture spec sizes. If you can't find it, you can always manually calculate about how big the tire will be by doing this, let's use stock size (275/55/20)

275 (width of tire in MM)

55 (ratio of how large 1 section of sidewall is compared to width of tire)

20 (rim size)

So 275 x .55 = 151.25 x 2 = 302.5 --MM to inches--> 11.9 + 20 = 31.9" tall. Stock size is actually 31.7 manufacture spec, but it gives you an idea of how large the tire is.
