Autoride Suspension Replacement with Bilstein 5100's

[JT 07LTZ]

I just want to make sure I have all the right parts I will need to do the install correctly, have a decent ride, and not have any dash lights.

I currently have a Rough Country 2" level up front and 1" coil spacers in the back with the stock autoride suspension that is shot.

These are the parts I have put together to order after a lot of research:

2x Bilstein 24-186940 - Bilstein B8 5100 Series Shocks (fronts)
2x Bilstein 24-187237 - Bilstein B8 5100 Series Shocks (rears)
2x Moog 81069 Coil Springs (rear springs to replace soft autoride springs)
4x Moog K160072 Coil Spring Insulator (top and bottom of rear shocks)
4x Uxcell 25W 3.9 Ohm 5% Wirewound Resistors


I have two other questions:
1. I have heard that the Moog coil springs raise the rear some. Should I install without the rear spacers so I am still leveled?

2. If I keep the rear spacers, can I set the front 5100's to the next notch up from stock height to lift the front of the truck more?
I have read conflicting opinions of going above 2.5" of lift in the front with 4wd and it causing issues.

Thanks guys!

Looks like you have all the right parts. I would go ahead and set the front shocks at 1/2" lift. Install everything together and measure fenders when done. Disconnect the ride height sensor too cause that changes voltage to the shock as suspension travels. Not 100% if any codes pop up from them being disconnected or not. If so measure voltage and resistance on one when in normal position. Then you can order resistors for them. Post pics and let us know the results!

Thanks man. I didn't realize that the 5100 struts had a 1/2" setting. I thought the first notch was 1" up from stock. I will look into disconnecting the ride height sensors and see if I will need resistors for those. Hopefully this will give me a little more lift and ride a lot better than it does now.
Are there any other parts I should replace while I'm down there?

That should be everything but down the road if you want better upper ball joint angles you can get lift arms. This helps to gain clearance between droop stops and arms.

OK I'll check them out. So just to be clear, should I keep the rear 1" spacers in if I set the front shocks to 1/2" lift on top of the 2" spacer I already have? I read that the new Moog rear Springs will give me some lift over the autoride Springs I'm replacing.

Yeah they will give you some lift but still think with 1" spacer you will need 2.5" up front. What's your current fender heights?

Sorry if I'm kind of jacking the thread, but figure it's better to ask here then make a separate thread for basically the same topic. Got my RC 3.5" lift on now, and I'm wanting to do something similar to this, and delete autoride, but I have a few questions.

1 - Should I go for the Moog Z71 springs for the rear, or lift springs, like 1-2" lift springs for rear?
2 - I'm either doing rancho or bilstein 5100's for shocks (bilsteins if I can spare the extra cash, and would much prefer them) but I'd like to know, for the front strut, can I buy 4 of the MOOG 81069 Z71 springs and use those for the strut and rear, or are the springs in the front and rear different?

Just get rear springs and swap them out for the rear springs. Front springs are the same for auto ride as far as I can tell with part numbers. Run bilstein 5100 front and rear.

Just got all the parts in! I'll do the install early next week. (excuse my daughter's mess)

I totally forgot to disconnect the ride height sensors. Is it really important to do? Im guessing the change in voltage can burn up the resistors.

Correct that's why they need to be disconnected because it will burn up resistors

 

[JT 07LTZ]

Ok thanks man. Hopefully it doesn't throw any codes.

I just unplugged all of the ride height sensors. I turned the truck on and didn't have any lights but I'll see what happens when I drive tomorrow.

Hope you got a chance to see the resistor install post I finally made today

Keep us posted on any issues that might pop up after driving around. And not yesterday but saw it this morning. Great work!

OK so after driving around some today after disconnecting the ride height sensors, I had the service suspension light come back on. I haven't pulled any fuses for the suspension yet.

Any ideas?

The computer uses the ride height sensors to control electronic dampening on the shocks along with rear air ride height. You should get some resistors for the sensors to disable them also to a standard position. I would use a multimeter to measure volts and resistance of switch then get compensating resistor to cancel out signal. Then you need to remove fuses for air compressor but not sure if that will cause lights in dash either.

That all makes sense. These trucks are really a pain in the ass. I'll get some readings and figure it out.

Part of me wants to just disconnect the height Rods from the hubs and glue them in place on the sensor so it will always be at the right "height"

That's the same thing as resistors. So you could secure the rods to the liner with some zip ties and it will stop the message. Still have to figure out how to keep the air compressor off with no codes. Only heard if you pull both fuses it's off. It might have a dash icon. They really made this truck so damn complicated for stupid air ride. I really wish my Denali didn't have it from the factory.

 

[JT 07LTZ]

I might try that if I can get it to match the right angle on the arm coming off the sensor. My compressor is burnt out anyway so it never runs. If I can get away without pulling the fuses I probably wont.

I wish I didn't have autoride either. It's been nothing but a pain.
