Fox coilovers with xineering magnaride delete kit

[Fifty]

OK, so there is a wrench for adjusting that spring perch. You can do it with the shock on the truck. You jack the truck up so there is no weight on that wheel.
Google coil over wrench, or call fox and find the one thats specific to the 2.0 fox and their little teeth.

I have a collection of about 5 different types....

NO SPRING COMPRESSOR NEEDED

Yea, I had my wife order one several days ago on amazon that looks compatible to my shock. But I am kinda guessing at that though because there really isnt much info on it. And fox’s website didnt even have one. The one she ordered was like a measly $7. Why the hell a nearly $1000 set of shocks dont come with the wrench that is needed to adjust them completely blows my mind.

And from my understanding, the tension still needs to come off the springs before using it or it will damage the threads. Even when the wheel is off the ground there is an extremely large amount of force on that nut.

Those wont work. Completely different nut.

Heres what I had her order of amazon...

Thanks for the suggestions though, fifty! I need all the help I can get on this!

No worries! You will be able to spin the nut with the preload. Sometimes spraying a little wd40 or other type helps it spin. But yeah, it will spin with the preload!

When you say preload, you mean just using the wrench? Or taking some preload/tension off the spring before using the wrench?

Also, my main dilemma here at the moment is the cross threaded nut one shock has now. Not sure what to do. Maybe put it in a strut machine like Oh Kee Pah posted, and then carefully cut it off of there? Then spin a new nut back on. Im not worried about any damaged threads where the nut is currently at because I will not be running them up that high.

I bet the Suburban is riding a lot better with those Fox 2.0's up front!

I have just over 4,000 miles on my Xineering GM Shock Delete circuits, Fox 2.0 Coilovers up front, 1" spacer in the rear running on 275/60r20 NITTO Ridge Grapplers.

YES - the Fox 2.0 front coilover assembly comes SET OUT OF THE BOX @ +2".

When I first put my Fox shocks on the front of my Tahoe I saw a 3.25" ride height increase. You can believe my surprise as my goal was 1.75-2" of front ride height increase. I understand there is a little settling, but...
So I called Fox. Technically, the 2.0 is "designed" for the Silverado. So, differences in front-end weight on your vehicle vs. a stock Silverado could have some serious effect on the pre-loading of the Fox shock. Also, depending on the age and model of your OE front shocks, there could have been some sagging...

In the end, I decreased the pre-load setting to +1.75" and got the Tahoe leveled out around +2.25" from my original ride height measurements. The ride is hands down amazing compared to the OE magneride control I previously had running on the suspension.

Xineering's circuits make it possible to delete your magneride control and build the suspension of your choosing for the most part. My goal was a 2" level using coilovers vs. a kit. By going with the Fox coilovers I have increased my down travel, improved handling and general ride feeling, improved off road capabilities and increased ground clearance via larger tires via the 2" level up front and 1" rear spacer.

Happy trails!

Quick question... when you say you decreases the preload by +1.75”, what exactly does that mean? You lowered the nut that distance?

Im trying to get an idea how much I need to lower the nut so I only gain around 1.5-2” of lift over factory height. I dont want it any higher than that. And I would really rather not have to take these damn things in and out each time doing trial and error height settings. However, like fifty said maybe I can adjust them while installed with the wrench.

Thanks guys, I really appreciate it!

What's the part number for the fox shocks? Looks pretty good.

Oh yea, I dug a box out of the trash the other day and snagged a few pics of the part numbers for ya...

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?

 

[olyelr]

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.

 

[Nokturnal]

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?

 

[Nokturnal]

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
