Much appreciated.

Since we are lowered, I think I'm gonna go with the atomic fab and performance coil over brackets and stock height viking coil overs. It says 08-14 but I'm almost positive it'll work for me. I'll be sure before ordering, lol

where you able to lower down the coilovers?

Nope, not yet. Still waiting on a new nut from Fox. Its been a clusterfawk to say the least, but all because of my own stupidity.

Plan is to get the new nut, go to a place that has an actual strut machine, fully unload the coil pressure (get it away from the nut), carefully cut the stripped nut off the shock body, put the new nut on in a lower position and be done with it.

****** part is, I have not been able to figure out exactly how much to lower the nut for a desired right height. Nobody can seem to give me a rough idea. So I guess it will be a trial and error thing... lower it a little, reinstall shock/tires and see what it looks like... then repeat if necessary till I find the desired ride height.

I think you're making a good decision going to the wall mounted coil compressor. When I spoke with Fox months ago they told me that's what needed to be done. That the threads could be ruined if trying to use a wrench or other methods.

If you are looking for the 1.5-2" Front ride height increase, I suggest starting at 1/4" or 0.25" decrease on the Fox threads. ALSO, mark the thread where you started (stock/out of the box) and then the thread where you end. If the Fox shocks act similar to mine, I think the 1/4" will get you to an actual decrease of around 1/2" or 0.5" decrease to stock, maybe more. Hopefully you'll end up somewhere around 1.5 - 1.75" ride height increase from original measurements.

There is also a "Ride Height Trim Procedure" that goes along with any GM Suspension work. As per my friends at Xineering.com (manufacturers of GM Shock Sims):

"It is a function used by the GM Dealerships scan tool to re-calibrate the suspension control module for any changes in ride height or ride height sensors to set the 'zero' ride height position of the vehicle.
It reads the ride height sensor voltages, stores them in memory, and sets them as the normal ride height position

The Suspension Control Module (SCM) is calibrated from the factory for its stock ride based on the ride height sensor voltages. This is the stock 'zero' suspension travel position for the magneride system.

As the vehicle drives (moves up/down, side to side) an algorithm determines how much electrical current (mA) to send to each magneride shock in order to maintain a smooth ride. The amount of current sent to a shock is proportional to how hard or soft the control module wants the shock to dampen.
If the ride height of the vehicle changes, due to a shock or spring replacement
OR If any ride height sensors have been replaced
A ride height trim calibration procedure is necessary, to re-zero the system."

Apologies for the slow response - family vacation, headaches and work catch up - Disney. Need I say more?

Thanks for the reply! Hope vacation was fun!!!

So your saying maybe drop the nut down a quarter inch, and start there?

 

[olyelr]

Im not so sure I need to mess with right height sensors at all. The front is deleted, and the rear I would prefer to leave at the stock height.

I just recently had my front Monroe Shocks (MRC deleted) pulled off and went with these Fox Coilovers and fox 2.0 in the back and got rid of the auto leveling factory shock.

To my shock, after install my front is lowered 2.5” and my rear dropped 1”. I have the 4” Fabtech kit AND a 1” spacer up front and my fender is measuring 39.5” vs 42” previously. My vehicle front was higher with just a maxtrac 3” leveling kit.

I had the work done in San Antonio and drove right back to Midland and the next day measured my fenders after it DEFINITELY seemed lower all the way around. The guys at Maximum Altitude said the rear dropped prob bc the auto level feature delete. But I’m at a total loss for why my front would’ve dropped 2.5”. They installed the fox coil overs straight out of the box.

Any ideas?

Top is Fabtech 4” Kit with 1” front spacer. Monroe Shocks upfront and factory rear auto level. 42” front fender 42” rear.

Bottom is same setup except now has Fox Coilovers up front with 1” spacer and fox 2.0 rear. 39.5” Front 41” rear
